A case of spontaneously ruptured hepatic angiosarcoma resected after transcatheter arterial embolization

Abstract

Abstract Hepatic angiosarcoma is a very rare disease, but it has a poor prognosis. Here, we report the case of a 77-year-old man who was referred to our hospital for suspicion of hepatocellular carcinoma and cancerous peritonitis. Based on the imaging findings, a diagnosis of spontaneously ruptured hepatic hemangioma was made. Six days later, the patient was transported to the hospital in a state of shock and an emergency transarterial embolization was performed. He underwent lateral hepatic segmentectomy 7 days later. Histopathologically, he was diagnosed with hepatic angiosarcoma. Fever was observed 21 days after surgery, and computed tomography was performed. Multiple liver masses, which ware increasing rapidly, were found, and hepatic angiosarcoma recurrence was confirmed. He requested home medical care and died at home 36 days after surgery. When a tumor diagnosed as a hepatic hemangioma by imaging has ruptured, the possibility of hepatic angiosarcoma should be considered.
