Abstract:
A hepatic angiosarcoma is a rare primary malignant neoplasm, which accounts for only 2% of all primary hepatic tumors. The prognosis of a hepatic angiosarcoma is very poor, and most patients die within a year of the initial diagnosis. We report a case of a hepatic angiosarcoma in a 57-year-old man. Although a dynamic CT had suggested a carvenous hemangioma 12 months earlier, the tumor size increased and spontaneously ruptured, so surgical resection was mandatory. A pathological examination, including immunohistochemical studies, showed positive staining for CD34 and Factor VIII, which confirmed the diagnosis of an angiosarcoma. Although dynamic CT is an excellent modality for the diagnosis of a cavernous hemangioma of the liver, hepatic angiosarcomas should be ruled out in selected cases, because they may present with very similar CT findings to benign hemangioma.
