Epithelioidhemangioendothelioma is a rare vascular tumor of bone, and rarely these lesions can present as unique and extremely aggressive tumor. We report a case of highly aggressive epithelioidhemangioendothelioma and discuss the imaging findings. CT brain plain study revealed a poorly-defined, mixed density expansile and lytic lesion involving the occipital bone with extension to the left side with poorly defined trabecula formation. There was significant but irregular enhancement after intravenous administration of contrast material and also marked bone destruction. Microscopic examination of the fine needle aspiration cytology showed a tumor composed of vascular channels lined by plump endothelial cells, which had enlarged hyperchromatic nuclei. In view of the extensive infiltration the patient was submitted for the radiotherapy.
上皮样血管内皮细胞瘤是一种罕见的骨血管肿瘤，这些病变很少表现为独特且极具侵袭性的肿瘤。我们报告一例高度侵袭性上皮样血管内皮细胞瘤，并讨论其影像学表现。CT 脑平扫显示枕骨内边界不清的混合密度膨胀性及溶骨性病变，向左侧延伸，小梁形成不清晰。静脉注射造影剂后有明显但不均匀的强化，也有明显的骨质破坏。细针抽吸细胞学检查显示肿瘤由血管腔组成，由饱满的内皮细胞衬里，细胞核增大、深染。鉴于广泛浸润，患者接受了放疗。
