Abstract The biliary hamartoma (BH), so called von Meyenburg complex, is a rare congenital disease of bile duct malformation. In clinical practice, the majority discovered incidentally. It was believed that typical image finding from cross‐sectional images could help us make correct diagnosis without histology. Ultrasound shear wave elastography (SWE) had been validated as noninvasive method for estimating liver fibrosis in patients with diseases. aim present study to explore ability SWE differentiation BH cirrhosis. We reported case series 14 cases were diagnosed and followed up at clinic Chimei Medical Center January 2016 December 2017. These found incidentally on routine ultrasonography examination because extraordinary coarse parenchymal pattern, findings portal hypertension. performed same time suspected or gained retrospective after confirmed by magnetic resonance imaging (MRI)/magnetic cholangiopancreatography (MRCP). classifies entity no (F0), mild (F1), severe (F2), significant (F3), cirrhosis (F4).
