RESUMO

Peribiliary cysts involve cystic dilatation and necroinflammatory change in the peribiliary glandular tissue of the larger biliary tree in association with portal hypertension or severe hepatobiliary disease. They are usually asymptomatic and found incidentally. However, rare cases causing symptoms or the mass effect of bile duct compression require differential diagnosis. They may be benign or malignant lesions resulting from narrowing of the bile duct and involving dilatation of the proximal intrahepatic bile duct. We recently encountered a case of peribiliary cysts associated with intrahepatic duct dilatation, and confirmed by surgery, and present the imaging and pathologic findings. Sonography and CT revealed the presence of multiple cystic lesions along the hepatic hilum, and the larger left portal tract and left intrahepatic ducts were dilated. Histopathologic examination indicated that the cysts were compressing the central bile duct.

RESUMO

PURPOSE: To review the type, incidence and radiologic findings and to evaluate the clinical significance of intrahepatic duct dilatation of choledochal cysts in children. MATERIALS AND METHODS: Ultrasonography and operative cholangiography of 49 consecutive children with surgically confirmed choledochal cyst were reviewed and classified according to the Todani's classification. Patients with intrahepatic duct dilatation in preoperative evaluation were routinely followed by ultrasonography after surgery of extrahepatic bile duct. The status of bileduct was evaluated by comparing with the preoperative ultrasonography. RESULTS: According to the preoperative evaluation, there were 19 cases(39%) of type Ia, three cases(6%) of type Ib, ten cases(20%) of type Ic, 15 cases(31%) of type IVa, two cases(4%) of type V, but no case of the type II, III, IVb in Todani's classification.In twelve of 13 patients (five cases of type I and eight cases of type IVa) who had been followed up after surgery of choledochal cyst, the previously noted intrahepatic ductal dilatation were no longer seen. CONCLUSION: The incidence of the types of choledochal cysts by Todani's classification shows no significant difference between our result and the other authors'. The intrahepatic ductal dilatation seems to be reversible and mainly secondary to extrahepatic obstruction by choledochal cyst. Thus, postoperative follow up examination is more important than preoperative classification of bile duct dilatation.
