Öğe A Case of Radial Scar: Findings of Mammography and MRI(Ortadogu Ad Pres & Publ Co, 2011) Ozmen, Cihan Akgul; Demirkazik, Figen Basaran; Akpinar, Meltem Gulsun; Akay, Hatice Ozturkmen; Ariyurek, MacitRadial scar is an idiopathic entity that represents a diagnostic challenge due to its similarity with breast cancer radiologically. The screening mammography of a 65-year-old female patient revealed asymmetrical parenchymal distortion. Breast ultrasound showed minor cysts and magnetic resonance imaging detected adjacent nodules with no contrast enhancement. Then, the lesion was excised with the help of mammography-guided needle localization method. Pathologic diagnosis was moderate ductal epithelial hyperplasia and radial scar. Although radial scar is a benign breast lesion, it mimics breast cancer mammographically and sonographically.Öğe A Case of Sheehan's Syndrome Admitting With Severe Hyponatremia(Turk Nefroloji Diyaliz Transplantasyon Dergisi, 2005) Danis, Ramazan; Ozmen, Sehmus; Parmaksiz, Ergun; Ozmen, Cihan Akgul; Yazanel, OrhanPostpartum necrosis of pituitary gland is one of the most common reasons of hypopituitarism. It is most commonly due to massive bleeding before or during delivery. Nonspecific symptoms like fatigue and weakness may confuse and delay the diagnosis. Patients with Sheehan's syndrome may rarely present with hyponatremia signs. A 55-year-old woman admitted to our nephrology department with stupor, severe hyponatremia (100 mEq/L), and hypoglycemia (56 mg/L). The diagnosis of Sheehan's syndrome was based on medical history, laboratory and radiological imaging findings. The patient's clinical picture improved dramatically after hormone and sodium replacement therapy. Sheehan's syndrome must be in differential diagnosis of old women with hyponatremia and it must be known that hyponatremia in those patients may be severe.Öğe Comparison of Chest Computed Tomography Findings in Patients with H1N1 and Coronavirus Disease-2019 Pneumonia(Galenos Publ House, 2024) Simsek, Sadullah; Ozmen, Cihan AkgulObjective: In this study, we compared the differences between highresolution computed tomography (CT) features of two types of viral pneumonia associated with H1N1 virus and coronavirus disease -2019 (COVID-19). Methods : A total of 25 patients with H1N1 pneumonia were compared with 150 patients with COVID-19 pneumonia. The findings were analyzed by IBM SPSS Statistics for Windows, version 22 (IBM Corp., Armonk, N.Y., USA). CT findings were compared between groups by chi-square test, and scale variables were compared using the t -test. Finally, significant findings for the H1N1 or COVID-19 groups were evaluated by logistic regression analysis. Results: The median age of COVID-19 pneumonia patients was 54.6 +/- 15.9 years, and the median age of H1N1 pneumonia patients was 46.2 +/- 12.4 years (p<0.01). H1N1 pneumonia patients were younger than COVID-19 pneumonia patients. Based on the distribution pattern, diffuse pattern, peripheral pattern, and bronchopulmonary infiltration were observed more frequently in COVID-19 pneumonia (46.0%, 80.7%, 49.3%, respectively, p<0.05). Mediastinal lymphadenopathy and pleural effusion were observed more frequently in patients with H1N1 pneumonia (24% and 36%, respectively, p<0.05). Logistic regression analysis demonstrated that advanced age and a diffuseperipheral pattern indicated COVID-19 (p=0.031, p=0.029). Conclusion: Most of the lesions caused by COVID-19 pneumonia are located in the peripheral region and near the pleura, whereas those caused by influenza virus pneumonia are far from the peripheral region.Öğe Diameters of normal thoracic vascular structures in pediatric patients(Springer France, 2009) Akay, Hatice Ozturkmen; Ozmen, Cihan Akgul; Bayrak, Aylin Hasanefendioglu; Senturk, Senem; Katar, Selahattin; Nazaroglu, Hasan; Taskesen, MustafaPurpose To determine the normal range of aortic and pulmonary artery diameters on chest CT, and to search a constant ratio when the diameters of thoracic vascular structures are compared with an internal reference. Methods Contrast-enhanced chest CT scans of 133 pediatric patients were retrospectively evaluated. Diameters of ascending and descending aorta, main pulmonary artery, right and left pulmonary arteries and a constant thoracic vertebra were measured. The mean ratios of thoracic vascular diameters to the diameter of the thoracic vertebra were calculated. Results There was a positive correlation between the age of the patients and vascular diameters. The mean ratios of vascular diameters to the diameter of thoracic vertebra, ranged from 1.1 for the ascending aorta to 0.70 for the right and left pulmonary arteries, were consistent. Conclusions Diameters of thoracic vascular structures increase with age. The consistent vertebral to vessel ratios can be useful in evaluation of chest CT of pediatric patients.Öğe An Evaluation of Preoperative Computed Tomography on Patients with Chronic Otitis Media(Springer, 2012) Yildirim-Baylan, Muzeyyen; Ozmen, Cihan Akgul; Gun, Ramazan; Yorgancilar, Ediz; Akkus, Zeki; Topcu, IsmailThis study aimed to compare the veracity of computed tomography findings on patients undergoing surgery for chronic otitis media (COM) with the surgical findings, and to determine to what extent the preoperative computerized tomography (CT) findings are useful to the surgeon. A series of 56 patients with COM undergoing preoperative CT scanning followed by surgical exploration of the middle ear and mastoid. Operative notes were recorded and data collected on the nature of soft tissue masses, the status of the ossicles, presence or absence of facial canal dehiscence and semicircular canal (SCC) dehiscence and the presence or absence of dural plate erosion, and sigmoid sinus thrombosis. Fifty-six patients were recruited in the study, 30 males and 26 females. The age range was from 16 to 67 years with a mean of 26.51 +/- A 1.4 years. The preoperative CT scan imaging in cases of cholesteatoma, ossicular chain erosion and SCC dehiscence have good correlation with the intraoperative findings. The specificity of preoperative CT scan in detecting facial canal dehiscence, dural plate erosion and sigmoid sinus thrombosis in patient of COM were weak. Preoperative computed tomography evaluation is fairly useful especially in cases of cholesteatoma. According to the results of this study, CT is of value particularly in the definition of cholesteatoma, and in determining ossicular chain erosion and semicircular canal fistula.Öğe Evaluation of the multi-slice computed tomography outcomes in diaphragmatic injuries related to penetrating and blunt trauma(Elsevier Science Inc, 2018) Turmak, Mehmet; Deniz, Muhammed Akif; Ozmen, Cihan Akgul; Aslan, AydinPurpose: Traumatic diaphragmatic rupture is a diagnostic challenge for both surgeons and radiologists and generally occurs secondary to blunt and penetrating trauma of thoracoabdominal region. Material and methods: 56 patients who underwent surgical. procedure due to blunt or penetrating trauma were included to the study. Results: There were 37 diaphragmatic ruptures in the left side and 19 patients in the right side. The most common radiological finding was the direct monitoring of defect (54,3%). Conclusion: Findings suggestive of diaphragmatic rupture must be carefully evaluated in patients with blunt or penetrating thoracoabdominal trauma.Öğe The frequency of intracranial arterial fenestrations: A study with 64-detector CT-angiography(Elsevier Ireland Ltd, 2011) Bayrak, Aylin Hasanefendioglu; Senturk, Senem; Akay, Hatice Ozturkmen; Ozmen, Cihan Akgul; Bukte, Yasar; Nazaroglu, HasanFenestration is a vascular variation that begins with a common origin, then splits into two parallel luminal channels and rejoins distally. Potential association between anomalies of cerebral circulation and increased occurrence of aneurysm makes intracranial arterial fenestrations important. The planning of intracranial arterial interventions may be complicated if a fenestration occurs proximal to the site of intended treatment. This study is planned to determine the frequency of fenestrations on CT angiography and to search whether there is relationship between aneurysms and fenestrations. CT angiographies of 395 consecutive patients, performed by 64-detector CT, were retrospectively reviewed for aneurysms and fenestrations. Overall fenestration frequency, fenestration frequency in patients with and without aneurysm, and aneurysm frequency in patients with and without fenestration were searched. Demographic characteristics of patients were also compared. Overall fenestration frequency was 12.9%. Vertebrobasilar system (5.56%) and anterior communicating region (5.32%) were the two most frequent sites of fenestration. The rate of fenestrations was not significantly different between patients who had and did not have aneurysms. Mean age was significantly higher, and females were predominant in patients with aneurysms. However our results did not show significant difference in age and sex of patients with fenestrations. The frequency of fenestrations in this study is higher than in previously published radiological studies, suggesting that fenestrations are relatively common. There is no significant relationship between the frequency of aneurysms and fenestrations. (C) 2009 Elsevier Ireland Ltd.

These rare complex anomalies were diagnosed in a 5-year-old boy by 64-slice multidetector CT (MDCT). This technique provides high-quality visualization of vascular, bronchial and parenchymal structures in a single session, such that no further invasive techniques are required. One obvious disadvantage of MDCT is the radiation exposure, especially in paediatric patients. The use of a single phase of contrast material administration reduces radiation exposure. The workstation platforms of MDCT systems allow multiplanar 2-D and 3-D postprocessing. As a result, various complex pathologies, such as that discussed here, can be diagnosed following a single imaging session with a certain precision.Öğe Incidence and management of isolated subsegmental pulmonary embolism(European Respiratory Soc Journals Ltd, 2013) Ates, Gungor; Ozmen, Cihan Akgul; Bogatekin, Gulhan; Nazaroglu, Hasan; Yildiz, Tekin; Topcu, A. Fusun; Bayhan, Seher[Abstract Not Available]Öğe MDCT Findings of Denim-Sandblasting-Induced Silicosis: a cross-sectional study(Bmc, 2010) Ozmen, Cihan Akgul; Nazaroglu, Hasan; Yildiz, Tekin; Bayrak, Aylin Hasanefendioglu; Senturk, Senem; Ates, Gungor; Akyildiz, LeventBackground: Denim sandblasting is as a novel cause of silicosis in Turkey, with reports of a recent increase in cases and fatal outcomes. We aimed to describe the radiological features of patients exposed to silica during denim sandblasting and define factors related to the development of silicosis. Methods: Sixty consecutive men with a history of exposure to silica during denim sandblasting were recruited. All CT examinations were performed using a 64-row multi-detector CT (MDCT). The nodules were qualitatively and semi-quantitatively analyzed by grading nodular profusion (NP) on CT images. Results: Silicosis was diagnosed radiologically in 73.3% of patients (44 of 60). The latency period (the time between initial exposure and radiological imaging) and duration of silica exposure was longer in patients diagnosed with silicosis than in those without silicosis (p < 0.05). Nodules were present in all cases with centrilobular type as the commonest (63.6%). All cases of silicosis were clinically classified as accelerated and 11.4% had progressive massive fibrosis (PMF). Mild NP lesions were the most prevalent in all six zones of the lung. The NP score was significantly correlated with the duration of silica exposure, the latency period, presence of PMF, and pleural thickening. Enlarged lymphadenopathy was present in 45.5% of patients. Conclusions: The duration of exposure and the latency period are important for development of silicosis in denim sandblasters. MDCT is a useful tool in detecting findings of silicosis in workers who has silica exposure.Öğe Migration of ventriculoperitoneal shunt into the lung by passing through the liver and the diaphragm(Aves, 2009) Nazaroglu, Hasan; Ozkan, Umit; Ozmen, Cihan Akgul; Akay, Hatice Ozturkmen; Senyigit, AbdurrahmanThoracic complications are rare after shunt placement for drainage of cerebrospinal fluid to treat hydrocephalus. We report a case of a ventriculoperitoneal shunt catheter that migrated into the lung by passing through the liver and the diaphragm. To our knowledge, there is no previously published report of a ventriculoperitoneal shunt that has migrated into the lung by a transdiaphragmatic and transhepatic route.Öğe Multiple Metastatic Tuberculosis Abscesses and Pott's Disease in an Immunocompetent Patient: Case Report(Ortadogu Ad Pres & Publ Co, 2011) Ates, Gungor; Ozmen, Cihan Akgul; Yildiz, Tekin; Kisin, Bulent; Akyildiz, LeventMetastatic tuberculous abscess (tuberculous gumma) is a rare form of cutaneous tuberculosis. A 16 years old female presented with painless cutaneous swelling at her neck and right thigh. She also suffered from back pain. She was diagnosed as soft tissue abscess according to ultrasound findings. These abscesses were painless and fluctuant. Chest computed tomography revealed an abscess involving the chest wall and the paravertebral area. Smear and sputum culture were negative for M. tuberculosis. In addition, smears and cultures of the abscess were negative for bacteria and fungi. There was no history of tuberculosis and no contact with patients with contagious tuberculosis. M. tuberculosis grew in the abscess culture. She was diagnosed as tuberculous gumma and Pott's disease. The patient recovered after antituberculous treatment. Subcutaneous abscess should be considered as tuberculosis abscess based on the negative smear and nonspecific culture results of pus.Öğe Quality of life, depression and anxiety in young male patients with silicosis due to denim sandblasting(Turkish Assoc Tuberculosis & Thorax, 2011) Yildiz, Tekin; Essizoglu, Altan; Onal, Suna; Ates, Gungor; Akyildiz, Levent; Yasan, Aziz; Ozmen, Cihan AkgulThe aim of this study was to estimate the quality of life, depression and anxiety in patients with silicosis due to denim sandblasting. This study was conducted on 50 young male patients with silicosis and 30 controls. A socio-demographic data form, Short Form-36 (SF-36), the Beck depression inventory (BDI) and the Beck anxiety inventory (BAI) were used to determine quality of life, depression and anxiety. The mean scores of SF-36, BDI and BAI were higher in the patients than in the controls. Correlation analysis revealed a strong negative correlation between all scales of SF-36 and BDI scores. Additionally, there was strong negative correlation between five scales of SF-36 and BAI scores. We suggest that silicosis might be detrimental to the quality of life and increase depression and anxiety in patients with silicosis due to denim sandblasting.Öğe A Rare Cause of Dysphonia: Laryngeal Lipoma: Differential Diagnosis(Ortadogu Ad Pres & Publ Co, 2009) Ozmen, Cihan Akgul; Nazaroglu, Hasan; Yildirim, Muezeyyen; Akay, Hatice Ozturkmen; Bayrak, Aylin H.Although lipomas are the most common benign tumors of mesenchymal origin, laringeal lipomas are rare. We report a case of laryngeal lipoma with computed tomography (CT) and magnetic resonance imaging (MRI) findings. A mass filling the left pyriform sinus was detected on the examination of a 52-year-old man admitted with dysphonia. The mass was originated from lateral side of left aryepiglottic fold, extending to subglottic area on the neck CT and MRI scans. The radiologic findings were compatible with laryngeal lipoma. Laryngeal lipoma, although rare, should be kept in mind for the differential diagnosis of patients admitted with dysphonia.Öğe Resection of Intercostal Hemangioma with Involved Chest Wall and Ribs in an 11-Year-Old Girl(Texas Heart Inst, 2010) Ulku, Refik; Onat, Serdar; Avci, Alper; Ozmen, Cihan AkgulWe report a case of an 11-year-old girl who presented with a slowly enlarging mass in the right posterolateral chest wall. Computed tomography showed a soft-tissue mass 8.5 x 7.5 x 5.5 cm in size, arising from the right posterolateral 9th, 10th, and 11th intercostal spaces. Magnetic resonance imaging confirmed a vascular mass. The patient underwent complete resection of the tumor, together with the right 8th, 9th, 10th, 11th, and 12th ribs and their intercostal muscles. Reconstruction of the chest wall was performed with methyl methacrylate and Mar lex mesh. Histopathologic examination of the tumor confirmed an intercostal cavernous hemangioma. At last examination, 6 months after the operation, the child was doing well, with no evidence of recurrence.

Methods: A 43-year-old woman was admitted to the hospital with left flank pain. Abdominal computed tomography showed bilateral hydroureteronephrosis and a malignant mass. The fine-needle aspiration biopsy was reported as retroperitoneal fibrosis. Stents were placed in both ureters. Two (2) months later, laparotomy revealed a mass located just below the origin of the inferior mesenteric artery. Bilateral ureterolysis and sigmoid colon resection was performed. Results: The pathology report was fibrosis and actinomycosis. She was given parenteral crystallized penicillin 4 x 5 million units/day for 21 days, followed by oral cotrimoxazole (960 mg) for 6 months. Conclusions: Because actinomycosis was not diagnosed either radiologically or pathologically, the patient underwent immunosuppressive therapy for 2 months preoperatively.Öğe The role of mediastinoscopy in the diagnosis of non-lung cancer diseases(Dove Medical Press Ltd, 2017) Onat, Serdar; Ates, Gungor; Avci, Alper; Yildiz, Tekin; Birak, Ali; Ozmen, Cihan Akgul; Ulku, RefikBackground: Mediastinoscopy is a good method to evaluate mediastinal lesions. We sought to determine the current role of mediastinoscopy in the investigation of non-lung cancer patients with mediastinal lymphadenopathy. Materials and methods: We retrospectively reviewed clinical parameters (age, gender, histological diagnosis, morbidity, mortality) of all patients without lung cancer who consecutively underwent mediastinoscopy in Hospital of Faculty of Medicine of Dicle University between June 2003 and December 2016. Results: Two-hundred twenty nine patients without lung cancer who underwent mediastinoscopy for the pathological evaluation of mediastinum during the study period were included. There were 156 female (68%) and 73 male (32%) patients. Mean age was 52.6 years (range, 16 to 85 years). Mean operative time was 41 minutes (range, 25 to 90 minutes). Mean number of biopsies was 9.3 (range, 5 to 24). Totally, 45 patients (19.6%) had previously undergone a nondiagnostic bronchoscopic biopsy such as transbronchial needle aspiration or endobronchial ultrasound-guided transbronchial needle aspiration. Mediastinoscopy was diagnostic for all patients. Diagnosis included sarcoidosis (n=100), tuberculous lymphadenitis (n=66), anthracosis lymphadenitis (n=44), lymphoma (n=11) metastatic carcinoma (n=5), and Castleman's disease (n=1); there was a diagnosis of silicosis in one patient and tymoma in one patient. Neither operative mortality nor major complication developed. The only minor complication was wound infection which was detected in three patients. Conclusion: Although newer diagnostic modalities are being increasingly used to diagnose mediastinal diseases, mediastinoscopy continues to be a reliable method for the investigation of mediastinal lesions.Öğe Sheehan's syndrome and its impact on bone mineral density(Informa Healthcare, 2009) Gokalp, Deniz; Tuzcu, Alpaslan; Bahceci, Mithat; Arikan, Senay; Ozmen, Cihan Akgul; Cil, TimucinIntroduction. Although there have been few studies investigating osteoporosis in isolated hormone deficiencies or other causes of hypopituitarism, the relationship between Sheehan's syndrome (SS) and osteoporosis has not been investigated. In the present study, we aimed to evaluate bone mineral density (BMD) in patients with SS in comparison with healthy women. Methods. Sixty-one patients with SS and 62 matched healthy controls were included. Biochemical, hormonal assessments and BMD evaluations were carried out in patients and controls, and a subgroup analysis according to menopausal status was done (premenopausal < 50 years; postmenopausal > 50 years). Results. The mean levels of serum anterior pituitary hormones were significantly lower in pre- and postmenopausal patients with SS compared with respective control groups (p < 0.0001). For both pre- and postmenopausal subjects, compared with respective controls, serum calcium and ALP levels, femur-T score, femur-Z score, spine (L1-L5)-T score, spine (L1-L5)-Z score and BMD values were lower, and phosphorus and parathyroid hormone (PTH) levels were higher in patients with SS. Conclusions. Patients with SS had low BMD. The possible mechanism responsible for osteoporosis may be hypogonadism, growth hormone deficiency and disorders of parathyroid hormone and calcium metabolism. But the contribution of each anterior pituitary hormone deficiency on bone loss should be clarified in further prospective studies.Öğe An unusual cause of ileal perforation: Report of a case and literature review(W J G Press, 2009) Akbulut, Sami; Cakabay, Bahri; Ozmen, Cihan Akgul; Sezgin, Arsenal; Sevinc, Mahsuni MertAn ileal perforation resulting from a migrated biliary stent is a rare complication of endoscopic stent placement for benign or malignant biliary tract disease. We describe the case of a 59-year-old woman with a history of abdominal surgery in which a migrated biliary stent resulted in an ileal perforation. Patients with comorbid abdominal pathologies, including colonic diverticuli, parastomal hernia, or abdominal hernia, may be at increased risk of perforation from migrated stems.
