Multiple Microhamartomas of the Biliary Tract System (Von Meyenburg Complexes) with Multiple Liver Cysts — Diagnostic Imaging and Laparoscopic Findings —

摘要: : We present two patients with multiple microhamartomas of the biliary tract (von Meyenburg complexes) liver cysts special reference to their diagnostic imaging and laparoscopic findings. Case 1 was a 76-year-old male case 2 51-year-old male, who later found have adenocarcinoma common bile duct as complication. The characteristic findings ultrasonography (US) were markedly heterogeneous there severe hyperechoic pattern in small cystic lesions. Computed tomography (CT) demonstrated low attenuation focal defects scattered throughout both lobes which showed no enhancement following application intravenous contrast medium. Laparoscopically, whitish nodular or stellate-shaped lesions, slightly depressed, dark greenish lesions various sizes on smooth surface lobes. Some adjoining. A histological study revealed collection proliferated irregularly dilated ducts ductules dense fibrous stroma. These are compatible microhamartomas. These features this disease, support close association between microhamartomas. Our hypothesis is that polycystic may result from dilatation
