The radiologic findings of prolapsed gastric mucosa through gastrojejunostomy stoma after gastrectomy is very characteristic, but recurrent gastric cancer, retrograde jejunogastric intussusception, and Hofmeister defect should be differentiated from it because of their simillar postoperative upper gastrointestinal series findings.The author reports 3 cases of prolapsed gastric mucosa through gastrojejunostomy stoma after Hofmeister's gastrectomy with brief review of the literature.

A Intraluminal Duodenal Diverticulum(IDD) is a rare congenital anomaly in adult, which presents as a mucosalpouch witinin the second portion of the duodenum and causes varying degrees of obstructive symptoms. The truepathogenesis of the lesion is still unknown, but it provably results from ballooning of acongenital duodenaldiaphragm with prolonged peristalsis. A pear-shaped intraluminal pouch resembling a barium-filled “wind sock” surrounded by a radiolucent halo, partially obstructing the duodenal lumen is the classic and diagnosticradiologic appearance. Proper identification of the papilla of Vater is important since this structure is oftenadjacnet ot the diverticulum. A case of IDD which occured in a 15-year-old boy with intermittent upper abdominalpain, nausea, and vomiting for 2 years is reported with review of the literatures.

Primary hepatic tuberculosis is extremely rare, but liver and spleen involvement secondary to tuberculosis isfrequentand of clinical importance, because of its demonstrability by biopsy. Complete absence of Tc-99m-SulfurColloid uptake of spleen due to splenic tubeculosis has not been reported. We experienced one case of liver andspleen tuberculosis which revealed complete absence of Tc-99m

Calcification is exceedingly rare in schwannomas. In the literatures, we found only three reports of schwannomas with calcification. We report two cases of intracranial calcified schwannomas, one in the anterior cranial fossa and the other in the middle cranial fossa.

A case of lymphatic cyst of the adrenal gland in a 55-year-old woman is described. The patient presented with vague abdominal pain, and abdominal CT and ultrasonography suggested a pancreatic cyst. The cyst, 10x8x6 cm in size, was found in the left adrenal gland; it was multilocular and septated with thin walls that were lined by a single layer of attenuated cells. The lining cells gave a weak positive immunoreactivity against factor VIII-related antigen and Ulex eurapaeus, and ultrastructural study revealed the lining cells to be of endothelial origin. Together with small tiny proliferative cystic spaces were intermixture of the normal adrenal cortical cells in the transition zone between large cysts and adrenal cortex. No histologic distinction between cystic lymphangioma and lymphangiectatic cyst was obtained; instead, a term of lymphatic cyst seems preferred unless otherwise confirmed. With its classification, the pathogenesis of adrenal lymphatic cysts is reviewed.

PURPOSE: To describe the characteristic CT findings of ameloblastomas in the mandibleand maxilla. MATERIALS AND METHODS: CT findings of 11 patients with ameloblastoma (9 cases in the mandible and 2 cases in the maxilla) proved by excisional biopsy were evaluated retrospectively with regard to the location, size, multilocularity, solid and cystic component, cortical destruction, soft tissue invasion, and contrast enhancement RESULTS: These were 8 multilculer expansile and I unicystic (developed in a dentigerous cyst) mandibler ameloblasftomas, and 2 unilocular maxillary ameloblasftomas. All cases showed inhomogenously enhancing solid component, nine of which were larger than cystic component. Nine cases, larger than 5 cm in diameter, revealed either a focal or extensive cortical destruction with various degree of invasion into the adjacent structures. One maxillary ameloblastoma contained a thick calcification along the margin of the lesion. CONCLUSION: Maxillomandibular ameloblastomas appeared as expansile lesion containing enhancing solid component relatively larger than cystic portion and having cortical destruction in large lesions(5cm>). Maxillary ameloblastomas were unilocular in appearance in spite of multilocularity in mandibular counterparts.

PURPOSE: To evaluate whether there are any differences in MR findings between the childhood and the adult moyamoya disease. MATERIALS AND METHODS: We compared the brain MR findings in 22 children (13 boys and 9 girls, 2-18 years of age) who had moyamoya disease with 15 adult patients (7 men and 8 women, 19-55 years of age). The MR findings were classified as parenchymal-(infarctions and intracranial hemorrhages) and vascular abnormalities (intracranial vascular patency and moyamoya vessels). The difference in each of these MR findings was analyzed using Chi-squaretest and Fisher's exact test (two-tailed). Out of 22 children, two children with normal MR finding were excluded from the statistical analysis. Moyamoya diseases were diagnosed angiographically in all adult patients. In children, they were diagnosed by MR imaging, MR angiography(6), and/or conventional cerebral angiography(18). RESULTS: In children, cerebral infarctions were observed in 20 of 22 patients (91%) (cortex 86%, periventricular white matter/centrum semiovale 32%, basal ganglia 10%). In two patients, there was no parenchymal abnormality. Intra-cranial hemorrhages were not demonstrated in any patients. In adults, intra-cranial hemorrhages(intracerebral hematoma, intraventricular hemorrhage, alone or combined) were demonstrated in 10 of 15 patients(67%). Cerebral infarctions with or without intracranial hemorrhage were detected in 10 of 15 patients(67%)(cortex 40%, periventricular white matter/centrum semiovale 53%, basal ganglia 20%). The difference in parenchymal abnormalities between the childhood and the adult moyamoya disease was statistically significant (p=0. 000164). There was no significant difference between the two groups with regard to the occlusive changes of the internal carotid and middle cerebral arteries or to moyamoya vessels(p> 0.01 ). CONCLUSION: This study could prove the fact that the principal clinical symptoms in the childhood moyamoya disease were due to cerebral infarction and those in the adult cases were due to infarction and intracranial hemorrhage. In addition, cortical infarction was more prevalent in children and infarction in periventricular white matter/centrum semivoale and basal ganglia was more frequentin adults. There was no significant difference in vascular abnormalities between the two groups.
