In a jaundiced patient, it is important to ascertain as early as possible whether the bile duct is dilated. Ultrasonography, computed tomography & conventional cholangiography are widely accepted methods of determining the size of the extrahepatic bile ducts. But there is a considerable discrepancy among the size of the bile duct as measured from them. So the author analyzed and compared the respective diameters of the bile ducts in Korean normal adults as measured from cadaver, IV cholangiography, ultrasoud and computed tomography. The materials were 45 cases of cadaver, 38 cases of IV cholangiography, 100 cases of ultrasonography & 55 cases of computed tomography. The results were as follows ; 1. The diameters of the bile ducts were 7.58±2.26mm at CHD & 8.04±2.42mm at CBD from cadaver ; 5.38±1.90mm at CHD & 6.58±2.37mm at CBD from IV cholanglography ; 3.24±1.13mm at CHD & 4.71±1.48mm at CBD from ultrasonography ; and 4.56±1.51mm at CHD & 5.87±1.68mm at CBD from computed tomography. 2. The diameter of the bile duct was greatest in cadaver, and then reduced in IV cholangiography, computed tomography and ultrasonography in this orde.r 3. There were no size discrepancy between the diameter of the common hepatic duct and that of the common bile duct. 4. There were no discrepanry of the diameter of the bile duct by sex.

PURPOSE: It may be difficult to differentiate renal cell carcinoma involving collecting system from renal urothelial tumor invading into renal parenchyma. The purpose of this study was to assess the differences of CT findings between two conditions. MATERIALS AND METHODS: CT findings of 5 cases of renal cell carcinoma involving the renal collecting systems and 10 cases of renal urothelial tumors invading the renal parenchyma were compared, and analyzed about the presence or absence of hydronephrosis, normal or abnormal CT nephrogram, renal contour changes due to mass and tentative diagnosis. The diagnoses were confirmed at surgery. RESULTS: Renal cell carcinoma showed hydronephrosis in only 20% and normal CT nephrogram and outward contour bulging in all cases. In contrast, renal urothelial tumor showed hydronephrosis(70%), abnormal CT nephrogram(60%), and preservation of reniform shape(100%). CONCLUSION: Renal contour changes and CT nephrogram may be useful in distinguishing both disease entities.

Somatostatinoma is rare endocrine tumor that was first described in 1977 by Ganda et al. and Larsson et al. simultaneously. It seems nonfunctioning at clinical level. But it may present with diabetes, diarrhea, cholelithiasis, steatorrhea, indigestion, hypochlorhydria, and anemia. In contrast with pancreatic somatostatinoma, duodenal somatostatinoma, in general, is clinically silent. Duodenal endocrine tumors show similar histologic pattern. Therefore, the definite diagnosis is performed by immunohistochemistry and electron microscopic examination. We have experienced a case of somatostatinoma of duodenum in a 62-year-old male. He has complained generalized pruritus for one year and jaundice for 2 weeks. Grossly, the mass was a intraluminary protruding, polypoid lesion with focal mucosal erosion at immediately distal to Ampulla of Vater. Histologically, it showed tall, cylindrical cells with distinct cell membranes, having granular cytoplasm and small innocent looking nuclei. No mitosis was seen. The tumor cells were arraged in small solid groups and trabeculae, separated by fibrovascular stroma. Immunohistochemically, the tumor cells were strongly positive with somatostatin and negative with several other hormonal and neuroendocrine markers. Ultrastructurally, the cytoplasm contains numerous, homogeneous low electron dense secretory granules, which are essentially similar to those seen in normal delta cells.
