Hepatic epithelioid hemangioendothelioma: review of 3 cases]

Hepatic epithelioid hemangioendothelioma (EHE) is a rare neoplasm of vascular origin. EHE is an intermediate-grade malignancy, between benign hemangioma and angiosarcoma, with variable aggressiveness. Involvement often is multinodular simulating metastases from a primatry extra-hepatic malignancy leading to delays in diagnosis. We report the imaging features in three cases of histologically proven hepatic EHE. The imaging features suggestive of EHE will be emphasized, especially for multinodular lesions suggesting liver metastases in patients with no known primary.
