The most common causes of conjugated hyperbilirubinemia after the first or second week of life are neonatal hepatitis and biliary atresia. Since these entities represent variable expressions of same pathologic process and have similar clinical, biochemical, and histologic features, differential diagnosis is extremely difficult. We prospectively studied 28 jaundiced infants by sonography and hepatobiliary scintigraphy. Final diagnoses included 12 biliary atresia and 16 neonatal hepatitis. Visualization of a normal-sized common bile duct or gallbladder was compatible with the diagnosis of neonatal hepatitis. Non-visualized or atrophic gallbladder no sonography coupled with non-visualization of bowel activity on scintigraphy was highly suggestive of biliary atresia. We believe that sonography plays valuable role in the initial evaluation of the infants with persistent neonatal jaundice. The combined use of sonography and hepatobiliary scintigraphy provides the most valuable in formation in suspected biliary atresia for prompt surgical treatment.

A case of 26 years old male having horseshoe kidney associated with giant hydronephrosis due to aberrant vessel was presented with a brief review of the literatures. The patient was managed by division of isthmus and nephrectomy with good result.

The advent of computerized cranial tomography made a greater advance in the diagnosis of very wide variety of intracranial lesions. Authors analyzed 58 pathologically proven sellar and parasellar tumors examined at Kyung Hee Un-iversity Hospital from Oct. 1977 to Jun. 1981 and the results were as follows; 1. The distribution of the tumors is 28 pituitary adenomas, 18 craniopharyngiomas, 5 meningiomas, 4 germinomas, 2 astrocytomas, and 1 sphenoid mucocele. 2. In pituitary adenoma, the precontrast CT scan of tumors appeared as isodensity in 11 cases, mixed density in 8 cases, high density in 6 cases, and low density in 3 cases, and associated with destruction of sellar turcica in 15 cases, calcification in 3 cases, and hydrocephalus in 2 cases. The postcontrast CT scan study revealed 24 cases of contrast enhancement, including 17 cases of homogenous and 7 cases of ring or rim enhancement. 3. In craniopharyngioma, the precontrast CT scan of tumors appeared as low density in 12 cases, isodensity in 4 cases and high density in 2 cases and associated with calcification in 16 cases, hydrocephalus in 15 cases and destruction of sellar turcica in 2 cases. The postcontrast CT scan study revealed no enhancement in 10 cases and contrast enhancement in 8 cases including 6 of ring enhancement and 2 heterogenous enhancement.

Xanthogranulomatous cholecystitis is a rare form of inflammatory disease of the gall bladder and was first described in 1970 by Christensen and Ishak as fibroxanthogranulomatous inflammation of the gall bladder. Recently authors experienced three cases of xanthogranulomatous cholecystitis, two of which were erroneously diagnosed as malignant tumor in preoperative clinical and radiological examinations. Grossly, the gallbladders were enlarged and the walls were thickened with yellowish granular necrotic areas ranging from a few millimeters to 1.0 cm in diameter. Microscopically, all of three cases showed diffuse infiltration of the foamy histiocytes containing bile pigments and mononuclear leukocytes associated with fibroblastic proliferation and foreign body reactions. The pathogenesis of the xanthogranulomatous cholecystitis is uncertain, but opinion favours an inflammatory response to extravasated bile probably, from ruptured Rokitanky-Aschoff sinuses. Three cases of xanthogranulomatous cholecystitis with brief review of literature are presented.

PURPOSE: In patient with blunt trauma of chest, supine AP x-ray cannot differenciate the lung contusion, laceration, atelectasis, and hemothorax definitely. Therefore, computed tomographic evaluation is needed for accurate evaluation of the injuries. In our knowledge, there are few reports about CT findings of blunt chest trauma, in our country, therefore we tried to fiud the characteristic CT findings in patients with blunt trauma. MATERIALS AND METHODS: We analyzed the plain x-ray and CT image of 4 patient with blunt chest trauma. Location and morphology of lung parenchymal contusion and laceration, hemopneumothorax, chest wall injuries and location of chest tube. RESULTS: Lung parenchymal contusion was noted in 53 segments. of 16 patiants'infiltration(n=27 segment), and multiple nodular pattern was noted in 15 segment, pattern of consolidation along the lung periphery was seen in 11 segment. Laceration was noted in 18 lesion and most commonly located in paravertebral area(b=8). CONCLUSION: CT scan of chest in patient with blunt chest trauma, provides accurate informations of the pattern of injuries, and localization, therefore, should be performed as po9ssible.
