Abstract
An epithelioid hemangioendothelioma is an intermediate grade tumor between hemangioma and angiosarcoma that frequently shows marked enhancement because it is a vascular tumor. Herein, we describe a rare case of a malignant epithelioid hemangioendothelioma of the femur that was mistaken as a benign lesion such as a simple bone cyst or fibrous dysplasia because the tumor had a benign cystic appearance on MRI and its imaging findings showed a histopathologic correlation.
