Eight patients with congenital cystic dilatation of the common bile duct (choledochal cyst) had been diagnosed by the ultrasonographical examination as a screening test for diseases of the hepato-biliary system at Tenri Hospital from 1970 to 1978. Final diagnoses of these patients were confirmed at operation. Only one of these involved male and the others females. The youngest was 2 month-old boy and the oldest 57 year-old female with arising of papillary adenocarcinoma in the cyst.On the ultrasonographical findings of these patients simple cystic pattern was revealed in 5 cases and mixed pattern in 3 cases. Differential diagnosis from the other cystic lesions in the right upper abdominal cavity and retroperitoneal space is a difficult problem on the ultrasonographical examination for this disease.Ultrasonographical examination, we think, is now more effective for this disease than other radiological diagnostic methods.
