Meningeal hemangiopericytomas are rare but aggressive tumors. All eight patients in this series developed recurrences, three with distant metastases. In six patients a lytic destructive lesion of bone was evident. CT scans in three patients demonstrated diffusely enhancing lesions. No tumor calcification was present. In five of six patients angiography was characterized by multiple irregular tumor vessels, an intense prolonged blush, and the absence of early draining veins. Differentiation of these tumors from meningiomas is discussed.
脑膜血管外皮细胞瘤罕见但具有侵袭性。本系列中的8例患者均复发,3例出现远处转移。6例患者可见骨质溶解性破坏病变。3例患者的CT扫描显示病变弥漫性强化。无肿瘤钙化。6例患者中有5例血管造影表现为多发不规则肿瘤血管、强烈持久的造影剂外溢以及早期引流静脉缺如。文中讨论了这些肿瘤与脑膜瘤的鉴别。
