    A rare hepatic tumor; hepatic epithelioid hemangioendothelioma
    (Derman Medical Publ, 2013-08-01) Akyıldız, Elif Ülker; Adım, Şaduman Balaban; Saraydaroğlu, Özlem; Kaya, Ekrem; Savcı, Gürsel; AKYILDIZ, ELİF ÜLKER; BALABAN ADIM, ŞADUMAN; SARAYDAROĞLU, ÖZLEM; KAYA, EKREM; SAVCI, GÜRSEL; Uludağ Üniversitesi/Tıp Fakültesi/Patoloji Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Genel Cerrahi Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Radyoloji Anabilim Dalı.; AAH-5481-2021; AAG-7319-2021; CBA-9252-2022; EMN-0789-2022; DOQ-8725-2022
    Primary sarcomas of the liver account for about 1% of all liver tumors. Two basic histological forms of these sarcomas are hepatic epithelioid hemangioendothelioma and angiosarcoma. Epithelioid hemangioendothelioma is a tumor of vascular origin that involves soft tissues and organs. Primary epithelioid hemangioendothelioma of the liver was first described by Ishak in 1984 and has an incidence of 1/100,000. We present a 68-year-old female case referred to the pathology department with an initial diagnosis of cholangiocellular carcinoma and diagnosed with primary hepatic epithelioid hemangioendothelioma with review of the literature.

    Unusual causes of small bowel obstruction and contemporary diagnostic algorithm
    (Wiley, 2008-06-01) Gümüstaş, Oğuzhan Güven; Gümüstaş, A.; Yalçın, Ramazan; Soylu, Ruhi A.; Savcı, Gürsel; SAVCI, GÜRSEL; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Radyoloji Anabilim Dalı.; AAH-5481-2021
    Intestinal obstruction is a common clinical abnormality. In 60-80% of cases, the small bowel is affected. Although postoperative adhesions are responsible in 60% of cases, the other frequently observed causes are hernia, strangulation and tumours, such as carcinoid, lymphoma or adenocarcinoma. In this pictorial essay, we presented the radiological findings of uncommon causes of small bowel obstruction as well as the suggested diagnostic algorithm.

    Differentiation of hepatocellular carcinoma from non-hepatocellular malignant tumours of liver by chemical-shift mri at 3 t
    (W B Saunders Co Ltd, 2019-10-01) Savcı, Gürsel; SAVCI, GÜRSEL; Öztürk, Kerem; Özkaya, G.; ÖZKAYA, GÜVEN; Soylu, E.; Yazıcı, Zeynep; YAZICI, ZEYNEP; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Radyoloji Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Biyoistatistik Anabilim Dalı.; 0000-0001-9664-2347; 0000-0003-0297-846X; AAI-2303-2021; E-1228-2018; A-4421-2016; AAH-5481-2021
    AIM: To evaluate the diagnostic performance of chemical shift magnetic resonance imaging (MRI) in distinguishing hepatocellular carcinomas (HCCs) from non-hepatocellular malignant tumours (non-HCCs) of the liver.MATERIALS AND METHODS: Patients with a diagnosis of malignant liver tumours examined at 3 T MRI were included in this retrospective study. Forty-seven HCCs and 75 non-HCCs that were studied with chemical-shift MRI between January 2012 and October 2016 were retrieved from the radiology database. Two blinded observers measured the signal intensities of the tumours, adjacent normal-looking liver parenchyma, and spleen on chemical-shift MRI. The fat quantification for HCCs, non-HCCs, and adjacent normal-looking liver parenchyma were calculated by using the spleen as a reference standard. The subtraction scores were calculated by subtracting fat percentages in liver parenchyma from those in tumours. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the fat percentage subtraction scores in distinguishing HCCs from non-HCCs were calculated.RESULTS: According to the optimal cut-off value acquired from both readers, a subtraction score >-0.26 was considered to be a HCC. Fat signal percentage subtraction scores were >=-0.26 in 45 of 47 HCCs and were <-0.26 in 69 of 75 non-HCCs. The sensitivity, specificity, PPV, and NPV of fat signal percentage subtraction score to differentiate HCCs from non-HCCs were found to be 95.7%, 89.3%, 84.9%, and 97.1%, respectively.CONCLUSION: Intracytoplasmic lipid in HCCs demonstrated by quantitative chemical-shift MRI may be a potentially powerful imaging biomarker to distinguish HCCs from the other malignant liver tumours.
