To explore the causes of hepatic angiosarcoma misdiagnosed as hepatic adenoma and review the relevant literature.

Clinical data of 1 patient with hepatic angiosarcoma who was misdiagnosed as hepatic adenoma in the First Affiliated Hospital of Nanchang University in April 2017 were analyzed retrospectively. The female patient, 47 years old, was hospitalized for the reason of a right hepatic lesion found by physical examination for 1 week. The informed consent of the patient was obtained and the local ethical committee approval was received. Plain and enhanced CT and MRI examination of the upper abdomen indicated a hepatic adenoma with malignant potential, while inflammatory lesion such as hepatic abscess was not excluded. The patient was initially diagnosed with hepatic space-occupying lesion after admission, and possibly a hepatic adenoma. Diagnosis, treatment and the efficacy of the patient were analyzed.

The patient received right hemihepatectomy in July 2017. The postoperative pathological examination result indicated hepatic angiosarcoma. The patient recovered well after operation, and was discharged on the 8^th day after operation.

Hepatic angiosarcoma is a rare malignant tumor derived from mesenchymal tissue. Its clinical manifestations and laboratory findings are non-typical. It is difficult to differentially diagnose hepatic angiosarcoma from hepatic adenoma, hepatic abscess with imaging findings, and pathological examination is needed for confirmation.
