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.
肝上皮样血管内皮瘤(EHE)是一种罕见的血管源性肿瘤。EHE是一种介于良性血管瘤和血管肉瘤之间的中度恶性肿瘤,侵袭性各异。其受累情况常为多结节性,类似原发性肝外恶性肿瘤的转移灶,导致诊断延误。我们报告3例经组织学证实的肝EHE的影像学特征。将重点强调提示EHE的影像学特征,尤其是对于无已知原发灶、提示肝转移的多结节性病变。
