Hemangioendothelioma is a rare vascular tumor characterized by endothelial tumor cells and variable malignant behavior, and it's not common for this lesion to involve the bone. Although there are a few reports of cranial involvement by hemangioendothelioma, only rare cases arising in temporal bone have been published. We present the radiologic findings of a 7-year-old boy who had a high grade hemangioendothelioma involving the temporal bone with intracranial extension. Evidence of flow voids on MR images suggested a tumor of vascular origin, and the ill-defined margins, cortical destruction and intracranial extension on the CT and MR images were correlated with the tumor's high histologic grade.
血管内皮瘤是一种罕见的血管肿瘤，其特征为内皮肿瘤细胞以及不同的恶性行为，该病变累及骨骼并不常见。虽然有一些关于血管内皮瘤累及颅骨的报道，但仅有罕见的颞骨病例被发表。我们报告一名7岁男孩的影像学表现，他患有高级别血管内皮瘤累及颞骨并向颅内扩展。磁共振图像上的流空信号提示肿瘤起源于血管，而CT和磁共振图像上边界不清、皮质破坏及颅内扩展与肿瘤的高组织学分级相关。
