In accessing the lower pole of the kidney, especially on the left side, the risk of colonic injury should be taken into consideration during percutaneous procedures, regardless of the patient's age and gender.

Background: Diffusion-weighted magnetic resonance imaging (DWI) is a widely-accepted diagnostic modality whose efficacy has been investigated by numerous past studies in the differentiation of malignant lesions from benign entities. Aims: The aim of this study was to evaluate the efficiency of diffusion-weighted magnetic resonance imaging in the characterization of renal lesions. Study Design: Diagnostic accuracy study. Methods: A total of 137 patients with renal lesions were included in this study. The median apparent diffusion coefficient (ADC) values as well as the b 800 and b 1600 signal intensities of normal kidneys, solid components of mixed renal masses, and total cystic lesions were evaluated. Results: There were significant differences between the ADC values of lesions and normal renal parenchyma, and between the ADC values of benign and malignant renal lesions on DWIs at b values of 800 and 1600 s/mm² (p<0.001 and p<0.001, respectively). There were significant differences between the ADC values of Bosniak Category 1 and 2 cysts and the ADC values of Bosniak Category 1 and 3 cysts on DWIs at b values of 800 s/mm² (p<0.001) and 1600 s/mm 2 (p<0.001). A cutoff value of 1.902 x 10 -3 mm²/s for the ADC with a b value of 800 s/mm² provided 88% sensitivity and 96% specificity for differentiation between benign and malignant renal lesions. A cutoff value of 1.623 x 10 -3 mm²/s for the ADC with a b value of 1600 s/mm² provided 79% sensitivity and 96% specificity (p<0.001) for the differentiation between benign and malignant renal lesions. Conclusion: Accurate assessment of renal masses is important for determining the necessity for surgical intervention. DWI provides additional value by differentiating benign from malignant renal tumors and can be added to routine kidney MRI protocols.

Cystic duct cysts are a rare congenital anomaly. While the other bile duct cysts (choledochus and the intrahepatic bile ducts) are classified according to the classification described by Tadoni, there is no classification method described by the cystic duct cysts, although it is claimed that the cystic duct cysts may constitute a new “Type 6” category. Only a limited number of patients with cystic duct cysts have been reported in the literature. The diagnosis is usually made in the neonatal period or during childhood. The clinical symptoms are nonspecific and usually include pain in the right upper quadrant and jaundice. The condition may also present with biliary colic, cholangitis, cholelithiasis, or pancreatitis. In our case, the abdominal ultrasonography (US) performed on a 6-year-old female patient who presented with pain in the right upper quadrant pointed out an anechoic cyst at the neck of the gall bladder. Based on the magnetic resonance cholangiopancreatography (MRCP) results, a cystic dilatation was diagnosed in the cystic duct. The aim of this case-report presentation was to discuss the US and MRCP findings of the cystic dilatation of cystic duct, which is an extremely rare condition, in the light of the literature information.

BackgroundFascioliasis is a disease caused by the trematode Fasciola hepatica. Cholangitis is a common clinical manifestation. Although fascioliasis may show various radiological and clinical features, cases without biliary dilatation are rare.Case reportWe present unique ultrasound (US) and magnetic resonance cholangiopancreatography (MRCP) findings of a biliary fascioliasis case which doesn’t have biliary obstruction or cholestasis. Radiologically, curvilinear parasites compatible with juvenile and mature Fasciola hepatica within the gallbladder and common bile duct were found. The parasites appear as bright echogenic structures with no acoustic shadow on US and hypo-intense curvilinear lesions on T2 weighted MRCP images.ConclusionsImaging studies may significantly contribute to the diagnosis of patients with subtle clinical and laboratory findings, particularly in endemic regions.

ÖzetKarın travmaları; baş, boyun ve toraks travmalarından sonra üçüncü en sık ölüm nedenidir. Travmalara bağlı ölümlerin yaklaşık % 10' u abdominal yaralanmalara bağlı gelişir. Künt solid organ yaralanmalarının nonoperatif tedavisinin önünü açan en büyük faktör Bilgisayarlı Tomografi(BT) olmuştur. BT, yaralanmaların anatomisini doğru bir şekilde ortaya koyar. İntraperito-neal sıvının miktarı, retroperitoneal yapılar ve gastrointestinal sistem hakkında çok önemli bil-giler verir. Günümüzde BT olmadan solid organ yaralanmalarının konservatif tedavisinin gerçekleştirilmesi çok güçtür. BT karaciğer, dalak, böbrek, pankreas ve sindirim borusunun trav-ma sonrası evrelemesi tedavi ve takibinde önemli katkılar sağlamaktadır. AbstractAbdominal trauma, the third most common cause of death after head, neck and chest in-juries. %10 of trauma related deaths develops due to abdominal injury. Computed Tomography (CT) has been paving the biggest factor in the way for nonoperative treatment of blunt solid organ injuries. CT exposes accurately to the anatomy of injuries. It is provide very important information about, the amount of intraperitoneal fluid, retroperitoneal structures, and the gastrointestinal system. Today, it is very difficult the realization of solid organ injury with conservative treatment without CT. CT provides a significant contribution staging of trauma liver, spleen, kidney, pancreas and digestive tract, treatment and follow-up. Keywords GirişKarın travmaları; baş, boyun ve toraks travmalarından sonra travmalara bağlı ölüm nedenleri içerisinde üçüncü sıklıktadır. Travmalara bağlı ölümlerin yaklaşık % 10' u abdominal yaralanmalara bağlı gelişir.1,2 Karın travmaları kafa ve göğüs travmalarından daha az ölümcül olmalarına rağmen, kendisine bağlı ölümlerin erken tanı ve tedavisi yapıldığında en yüksek oranda önlenebilir travma grubu olması nedeni ile önemini korumaktadır.3 Oluş mekanizması bakımından trafik kazaları, iş kazaları, yüksekten düşme ve darp gibi olaylar künt travma grubuna girerler. Künt solid organ yaralanmalarında, Avrupa ülkelerinde olduğu gibi, ülkemizde de trafik kazaları en ön sırayı almaktadır. 4Künt solid organ yaralanmalarının nonoperatif tedavisinin önünü açan en büyük faktör Bilgisayarlı Tomografi (BT) olmuştur.
