Öğe Agenesis of the right lung presenting as a pulmonary infection(W B Saunders Co Ltd, 2002) Nazaroglu, H; Mete, A; Bükte, Y; Simsek, M[Abstract Not Available]Öğe Cerebral hydatid disease(E M H Swiss Medical Publishers Ltd, 2004) Biikte, Y; Kemanoglu, S; Nazaroglu, H; Özkan, Ü; Ceviz, A; Simsek, MObjective: Cerebral hydatid disease is very rare, representing only 2% of all cerebral space occupying lesions even in the countries where the disease is endemic. The aim of this paper is to describe the characteristic features of cerebral hydatid disease in computed tomography (CT) and magnetic resonance imaging (MRI). Methods: We retrospectively reviewed the CT and MR imaging findings of 18 patients with pathologically confirmed cerebral hydatid disease over a period of 13 years (1990-2002). Results: The study group consisted of 17 cases of Echinococcus granulosus and 1 case of Echinococcus multilocularis (alveolaris). They were 12 male (66.7%), and 6 female patients (33.3%), ages ranging from 7 to 50 years with an average age of 20.3 years. Headache, vomiting and seizures were the predominant symptoms. Papilloedema was present in 14 patients (77.7%). Common CT and MR imaging findings of E. granulosus lesions were well-defined, smooth thin-walled, spherical, homogeneous cystic lesions with no contrast enhancement, no calcification, and no surrounding oedema. The lesion seen with E. multilocularis was a well-defined multiseptated mass consisting of solid and cystic components with calcification in the solid portion. Cystic lesions with surrounding hyperintensity of perifocal oedema with complete or incomplete rim enhancement were seen in two patients, and were labeled as complicated and infected cysts. Conclusion: Although cystic cerebral hydatid disease is well demonstrated by CT and MR examinations, CT is superior in detecting calcification in the cyst, when present, MR is better in demonstrating cyst capsule, detecting multiplicity and defining the anatomic relationship of the lesion with the adjacent structures, and it is more helpful in surgical planning.Öğe Giant intrathoracic extrapulmonary hydatid cyst manifested as unilateral pectus carinatum(Southern Medical Assn, 2002) Nazaroglu, H; Balci, A; Bükte, Y; Simsek, MLiver and lung are the most common sites of hydatid disease, but it can also be seen elsewhere in the body. Extrapulmonary intrathoracic location of the disease is rare. This case of giant intrathoracic extrapulmonary hydatid cyst manifested as unilateral pectus carinatum serves to illustrate that hydatid disease can produce various symptoms and that it may also exist in locations apart from lung and liver.Öğe High-resolution computed tomography in cases with environmental exposure to asbestos in turkey(Karger, 2000) Topçu, F; Bayram, H; Simsek, M; Kaya, K; Özcan, C; Isik, R; Senyigit, ABackground and Objectives: Although all parts of the lung can be affected as a consequence of asbestos exposure, most CT protocols tend to scan only the middle and lower parts of the thorax. The aim of this study was to investigate parenchymal and pleural lesions of persons exposed to environmental asbestos, using a high-resolution computed tomography (HRCT) protocol scanning the whole thorax. Methods: We analyzed the chest radiographs and HRCT scans of 26 patients who presented bilaterally with multiple pleural plaques related to environmental asbestos exposure. Results: Twenty-four cases (92%) had an abnormal HRCT suggestive of asbestosis. Apart from common HRCT changes related to asbestosis, we detected apical pleural thickening (APT) in 9 cases as well as a coarse honeycomb pattern adjacent to APT in 7 of these cases. Cavitary lesions due to pulmonary tuberculosis were observed on HRCT scans from 4 patients in total. Neither apical pulmonary fibrosis nor cavitary lesions were visible on chest radiographs. Conclusions: We suggest that the HRCT protocol for examining asbestos-exposed individuals with pleural plaques on chest X-rays should include the whole thorax, since the asbestos-related pathologies may involve all parts of the lung.

Basel.Öğe Laryngopyocele(Elsevier Sci Ireland Ltd, 2000) Nazaroglu, H; Özates, M; Uyar, A; Deger, E; Simsek, MA laryngocele is an air-filled dilation of the saccule of the larynx. An infected laryngocele is called a laryngopyocele. Our experience with a case of laryngopyocele with signs on computed tomography before and after antibiotic therapy is presented since laryngopyocele is more unusual.

Methods: We analyzed six patients with brucellar abscesses. who had symptoms mimicking lumbar disc herniation. The study group consisted of three women. and three men who were 15 - 67 (mean = 37) years old. Patients were imaged in the axial and sagittal planes with a I.0-T MR scanner using a spine coil. Results: The level of abscesses were accurate in 100% (six of six)of patients with MR imaging. MRI examinations revealed an extradural soft tissue mass which were iso- to hypointense compared to spinal cord on T1WI and hyperintense on T2-weighted images. By contrast study, diffuse homogeneous or slightly heterogeneous enhancements were seen. Conclusion: Lumbar extradural brucellar abscess can have lumbar disc disease symptoms. MRI may non-invasively and rapidly reveal the presence of spinal abscess and degree of extension to the spinal canal. Extradural brucellar abscess should be included in the differential diagnosis of radicular symptoms caused by disc herniation.Öğe Multilocular cerebral hydatid disease with extracalvarial extension(Amer Roentgen Ray Soc, 1999) Nazaroglu, H; Özates, M; Bilici, A; Simsek, M[Abstract Not Available]
