N/A Sixty-seven lesions of small hepatocellular carcinoma in 50 patients under 5cm in diameter detected by computed tomography (CT) were reviewed to characterize the CT feature. All 50 patients were studied with a CT-9800 scanner. CT scans were obtained both before and after administration of contrast medium given by bolus injection of 120 ml of meglumine iohatlamate. CT density of the tumor was classified as hypodense, isodense, and hyperdense on the basis of the difference in density between the lesion and the surrounding liver parenchyma. Detectability of small hepatocellular carcinoma on CT scans was divided into three categioies; Good: tumor is noted, and extent of tumor is clearly defined; Fair: tumor is noted, but extent of tumor is not defined; Poor: tumor is not noted. On nonenhanced CT scans, 40 cases (60%) showed hypodense masses and 27 cases (40%) showed isodense masses whereas all cases showed hypodense masses on contrast-enhanced CT scans. On nonenhanced CT scans, 27 cases (40%) were categorized as good, 13 cases (20%) as fair, and 27 cases (40%) as poor while 65 cases (97%) were categorized as good, and 2 cases (3%) as fair on contrast-enhanced CT scans. Additional CT characteristics of small hepatocellular carcinoma were well defined margin (99%), and peripheral hyperdense rim (44%). These results suggest that contrast-enhanced CT scans are better than nonenhanced CT scans in detecting and defining the tumor, and CT might be useful for characterization of small hepatocellular carcinoma.

Lack of validity and reliability in selection procedure for internship at teaching hospitals has become a nationwide serious issue, especially regarding its influence on undergraduate medical education. This article describes a case model of selection procedure for internship at Seoul National University Hospital aiming for appropriate measurement of clinical competency as well as a meaningful feedback to the undergraduate medical education. The modification of selection was based on two parts; a problem-based written examination and a clinical skill-attitude assessment. For the former, a total of 60 test items for 34 problem cases were developed, being provided with a variety of pictorials and figures to simulate a real clinical setting. The knowledge level of all test items were either interpretation or problem-solving, and multi-answer items were randomly included to minimize a risk of high chance scoring in multiple choice items. The clinical skill was assessed with 10 important skills with predesigned check list. We conclude that problem-oriented written examination together with clinical skill assessment is a way of improving the measurement of clinical competency and strengthens clinical clerkship effectively during the undergraduate clinincal studies.

N/A 22 patients with intrahepatic cholangiocarcinomas of the liver were examined with computed tomography (CT). Initial symptom was nonspecific such as upper abdominal discomfort or pain in majority. There was no patient with jaundice or liver cirrhosis. 13 patients (59%) showed positive skin or stool test for clonorchis sinensis. 17 patients had the peripheral type of cholangiocarcinoma and five patients had the main duct type. The tumors showed low-density rnasses in pre and postcontrast CT scan in all cases vith wide variation of homogeneity. The tumor margins were irregular in 18 patients (82%) and the degree of contrast enhancement of the tumor was minimal in 19 patients (86%). 13 patients, who had the clonorchiasis, showed mild, and diffuse dilatation r>f the intrahepatic bile duct in addition to the low-density mass. 12 patients (55%) showed extrahepatic metastasis. In peripheral type of the tumor, five patients showed fine, stippled or aggregated powderlike high-density areas in precontrast Cl scan that vere mucinous substances within the mass on pathologic section. Eleven patients showed markedly low-density masses even in postcontrast CT which corresponded to diffuse, microcystic change of the tumor on resected specimen. In main duct type, all patients showed focal ductal dilataion around the low-density mass. Intrahepatic cholangiocarcinoma should be the primary diagnostic consideration when characteristic CT findings are detected in noncirrhotic patient with clonorchiasis.
