Cystic Presentation of Primary Hepatic Angiosarcoma

Primary hepatic angiosarcoma is a rare malignancy arising from the endothelial cells. They account for 1% of all primary liver tumors. They are aggressive tumors and patients usually present with distant metastasis. Surgical resection is the mainstay of treatment, however recurrences are common. The overall survival of patient with hepatic angiosarcoma is only five months without any treatment. Addition of adjuvant chemotherapy with surgery seems to prolong the overall and disease-free survival. Their diagnostic dilemma is due to the fact of non-specific imaging findings mimicking other hypervascular liver tumors. Angiosarcomas are solid tumors arising from the endothelial cells. Cystic type of angiosarcomas are rare and those arising from the liver have not been reported. We are presenting a case report on a cystic primary hepatic angiosarcoma.
