title: [A case of liver abscess with subcapsular hematoma mimicking ruptured hepatic cholangiocarcinoma].
abstract: Subcapsular hematoma is a very rare complication of liver abscess. We report a case of liver abscess with subcapsular hematoma mimicking ruptured hepatic cholangiocarcinoma. A 59-year-old man presented with right upper quadrant pain and febrile sense. Computed tomography showed a low attenuated mass with extensive subcapsular hematoma on the right hepatic lobe. The initial impression was a hematoma caused by the rupture of cholangiocarcinoma. Hepatic arteriography was performed, but no active bleeding focus was found. After drainage of the subcapsular hematoma, a hematoma wall biopsy through the drainage catheter and a liver biopsy of the low attenuated mass were performed. The biopsies showed many neutrophils, macrophages, and granulation tissues consistent with an abscess, but no malignant cells were detected. After antibiotics therapy for 6 weeks, computed tomography was performed 4 months later, and revealed complete resolution of the hematoma and the low attenuated hepatic lesion.
