Embryonal Rhabdomyosarcoma of the Biliary Tree: A Case Report
Abstract
- Rhabdomyosarcoma are reportedly the most common soft tissue sarcoma occuring in childhood, but the
biliary tree is a rare site of origin for this tumor. Recently we experienced a case of embryonal rhabdomyosarcoma
of the biliary tree in a 30-month-old child. UItrasonography showed hypoechoic mass filling the dilated left. intrahepatic & extrahepatic bile ducts, and CT showed hypodense mass with heterogeneous enhancement after contrast infusion. Intraoperative cholangiography showed filling defects within the dilated left. intrahepatic & extrahepatic bile ducts. Postoperative MRI showed residual mass within the left. intrahepatic duct which was hypointense on T1WI and hyperintense on T2WI.
