A hepatic cyst complicated by hemorrhage with secondary revascularization mimicking mucin-producing cystic neoplasm: Radiologic-pathologic correlations

Cystic hepatic lesions are commonly encountered in clinical practice. Most of them are simple hepatic cysts such as biliary cysts. However, complicated biliary cysts with hemorrhage, necrosis, and organization pose diagnostic challenges since imaging findings overlap with those of neoplastic cystic lesions. Here, we report a case of biliary cyst complicated by hemorrhage with secondary revascularization with ultrasound, computed tomography, and gadoxetic acid-enhanced magnetic resonance imaging findings mimicking mucin-producing cystic neoplasm.
