    Accessory liver within the thoracic cavity
    (Springer France, 2018) Adin, Mehmet Emin; Cetincakmak, Mehmet Guli; Deniz, Muhammed Akif; Goya, Cemil
    Ectopic intrathoracic liver tissue is extremely rare. Studies are mainly limited to case reports. In the vast majority of reported cases, a diagnosis of intrathoracic liver tissue was made either after a thoracic surgery or during a postmortem examination. However, once included in differential diagnosis, surgical intervention or biopsy procedures may be avoided with optimal diagnostic approach. In the present study, we conducted a literature review and proposed a new classification method for accessory liver within the thoracic cavity. This approach may provide a better understanding of underlying pathophysiology and aid in determination of optimal diagnostic modality and clinical management of such cases. According to our literature review, type II ectopic liver is the most common subtype followed by types I and III. All types can be definitively diagnosed with imaging modalities. On the other hand, it is important to prevent patients, particularly children, from unnecessary radiation exposure during performance of sophisticated diagnostic imaging modalities. Ultrasound is a safe, low-cost and accessible imaging modality that has not been previously reported in diagnosis of this entity. With addition of Color Doppler Imaging, ultrasound may allow for diagnosis with high precision in types I and II, as demonstrated in the present study. Based on long-term follow-up of a case reported here, this study also illustrates the natural course of this entity via non-operative management. This approach may prevent an unnecessary surgical intervention.

    Bilateral cleft foot: Radiographic and prenatal ultrasound features of two siblings with a review of literature
    (Elsevier Urban & Partner Sp Z O O, 2016) Durmaz, Mehmet Sedat; Demirtas, Hakan; Hattapoglu, Salih; Kara, Taylan; Goya, Cemil; Adin, Mehmet Emin
    Cleft foot deformity, also known as ectrodactyly, is a rare congenital developmental defect of extremities caused by malformation in continuity of apical ectoderm. The syndrome typically involves malformation or absence of the central rays of the feet and is characterized by deformities like median deep clefts of distal extremities. Routine examination of feet during second-trimester ultrasound (US) may increase the detection rates of foot malformations. Many malformations can be diagnosed with 2-dimensional (2D) US, but 3-dimensional (3D) US also helps better understanding of the foot malformations. In the present study, we report the case of two brothers (a fetus and a 5-year-old) with cleft foot deformity. 2D and 3D second trimester US findings of one case and the foot radiography findings of the other are presented here.

    Detection of-incidental pulmonary embolism with multi-slice computed tomography in cancer patients
    (Elsevier Science Inc, 2017) Deniz, Muhammed Akif; Deniz, Zelal Tas; Adin, Mehmet Emin; Akil, Ferit; Turmak, Mehmet; Urakci, Zuhat; Cetincakmak, Mehmet Guli
    The aim of this study is to show the frequency of incidentally found (pulmonary thromboembolism) PTE in oncological patients and evaluate dispersion of incidents in terms of underlying primary tumor and seek risk factors associated with incidental PTE. Among one thousand oncology patients, 46 (4.6%) individuals found to have incidental PTE. Of positive patients, the highest proportion (24%) was belong to breast cancer group (n = 11). The most common location for pulmonary emboli was the lower lobe branch of right pulmonary artery (n = 33, 71.7%). Evident PTE had not been reported in final radiology reports of 21 cases.

    Echogenic splenic lesions in a child with type B Niemann-Pick disease
    (Wiley-Blackwell, 2013) Adin, Mehmet Emin; Önder, Hakan; Alabalık, Ulaş; 0000-0003-4551-8439
    We report the case of a 15-year-old boy with Niemann-Pick disease type B with characteristic sonographic findings of splenic involvement. There were multiple well-defined echogenic nodular lesions within the spleen parenchyma, and these lesions were surrounded by ring-like blood flow on color Doppler imaging. Most of the patients with Niemann-Pick disease type B are children and they undergo repeated imaging studies. Therefore, familiarity with sonographic findings of the disease is required.

    Kafa tabanı havalanması: vidian kanal ve eşlik eden anatomik yapıların yüksek çözünürlüklü çok kesitli bilgisayarlı tomografi ile değerlendirilmesi
    (2015) Adin, Mehmet Emin; Akgül Özmen, Cihan
    AMAÇ:Kafa tabanındaki çeşitliyapıların birbirleriyle olan ilişkisini detaylı incelemekve bazı özel durumların sıklığını araştırarak endoskopik kafa tabanı cerrahisinin planlanmasına katkıda bulunmaktır.GEREÇ VE YÖNTEMLER:Şubat-Temmuz 2014 tarihleri arasında Dicle Üniversitesi Radyoloji Anabilim dalına başvuran ardışık 640 olgunun yüksek rezolüsyonlu Çok Kesitli kafa tabanı Bilgisayarlı Tomografi (ÇKBT) görüntüleri incelendi. Kafa tabanında ve paranazal sinüslerde belirgin bir patoloji veya yer kaplayan kitlesel lezyon bulunan, artifisiyel görüntüler nedeniyle tanısal kalitede olmayan ve 18 yaşından küçük olan olgular çalışmaya dahil edilmedi. Geriye kalan normal veya normale yakın sınırlarda 171 olgu çalışmaya dahil edildi.BULGULAR:Sfenoid sinüsün havalanma paterni en sık sellar tipteydi.Sfenoid sinüslerin yaklaşık yarısında tek orta hat septumu mevcut olup olguların yaklaşık yarısında lateral sfenoid reses havalanması mevcuttu. Vidiankanalın ortalama uzunluğu kadın ve erkeklerde 16 mm olarak bulundu.Kanalın rostral-kaudal seyri en sık medialden laterale doğru olup ikinci sıklıkla düz kanal seyri gözlendi.Vidiankanalın en sık rastlanan havalanma paterni Tip 0 olup daha sonra azalan sıklıkla tip III, II ve I izlendi.Petröz ICA olguların büyük bir kısmında Vidiankanalın superiorunda yerleşmiş olup iki yapı aynı aksiyal kesitte izlenebilmekteydi.Onodi hücresi olguların yaklaşık dörtte birinde görüldü.ACP havalanması olguların yaklaşık dörtte birinde gözlenirken PCP havalanması %5 gözlenmekteydi.Çalışmaya dahil edilen olguların yaklaşık beşte birinde ICA protrüzyonu ve yaklaşık %3’ünde ise ICA dehisensisi mevcuttu.Olguların %11’inde OS protrüzyonu, %5’inde OS dehisensisi mevcut olup %4 OS’de ise hem protrüzyon hem de dehisensi mevcuttu.SONUÇ:Mevcut retrospektif gözlemsel çalışmada literatürde bulunan bazı tiplendirme ve yaklaşım modellerini revize ederek kritik role sahip olan yapıların detaylı anatomisini ortaya koyduk. Anahtar kelimeler:Çok kesitli bilgisayarlı tomografi,kafa tabanı havalanması, sfenoid sinüs, Vidiankanal.

    Utility of the Vidian Canal in Endoscopic Skull Base Surgery: Detailed Anatomy and Relationship to the Internal Carotid Artery
    (Elsevier Science Inc, 2019) Adin, Mehmet Emin; Ozmen, Cihan Akgul; Aygun, Nafi
    OBJECTIVE: To investigate key anatomic features of the vidian canal that have a critical role in planning and performing endoscopic skull base surgeries. METHODS: We reviewed skull base computed tomographic images of 640 consecutive subjects. Studies were analyzed in axial, coronal and sagittal planes. RESULTS: The mean (+/- SD) length of the vidian canal was 15.4 +/- 2.0 mm in female subjects and 16.6 +/- 1.7 mm in male subjects, and the difference between genders was statistically significant (P<0.001). The most common rostral-caudal course of the vidian canal was medial to lateral and was followed by the straight course, tortuous course, and lateral-to-medial course. The frequency of pneumatization pattern from most common to least common was types 0, III, II and I. Of 342 evaluated sides, the vidian canal was located below the level of the anterior genu of petrous ICA in 303 (89%) sides, at same level with the anterior genu of petrous ICA in twenty-five(7%) sides, and above the level of the anterior genu of petrous ICA in fourteen(4.1%) sides. CONCLUSIONS: A variety of previously undefined features of the vidian canal that can alter the course of surgical procedure were defined. The position of the vidian canal with respect to the petrous internal carotid artery (ICA) was extensively described. From a surgical standpoint, a working room inferior and medial to the vidian canal might not always be a safe approach, because the vidian canal could be located superior to the level of the anterior genu of petrous ICA according to our findings in the present study.
