【摘要】：目的:提高对颅内血管外皮细胞瘤(HPC)影像认识及诊断水平。方法:回顾性分析12例经手术病理证实的颅内HPC的CT、MRI及病理资料。结果:12例颅内HPC均为单发病变。11例位于颅内脑实质外,7例位于天幕上(2例跨大脑镰成长,3例位于大脑镰旁,2例位于外侧裂区),2例跨小脑天幕成长,1例位于鞍内并伸向鞍上,1例位于后颅窝小脑外。1例HPC位于中央旁小叶。12例的边缘均呈深分叶状改变。8例病变周边及内部有多发囊变,9例内部可见流空血管影。11例与硬膜囊相邻,9例以窄基底与硬脑膜相邻,2例以宽基底与硬脑膜相邻。肿瘤质地柔软,为红色或灰红色,血供丰富,部分肿瘤有包膜;肿瘤内多有薄壁血管,VIM染色阳性,VEM阴性。结论:对于与硬脑膜相邻的颅内脑外肿瘤,当肿瘤以窄基底与硬脑膜相邻,边缘呈深分叶状,肿瘤内部有多条流空血管,有囊变等征象时,要考虑到颅内HPC的可能。
[Abstract]:Objective: to improve the recognition and diagnosis of intracranial hemangiopericytoma (HPC). Methods: Ct MRI and pathological data of 12 cases of intracranial HPC proved by operation and pathology were retrospectively analyzed. Results all 12 cases of intracranial HPC were single lesions. 11 cases were located in the cerebral parenchyma. 7 cases were located on the supratentorial part (2 cases were located in the lateral fissure region, 2 cases were located in the lateral fissure area) and 2 cases were located in the lateral fissure region. 1 case was located in the saddle of the cerebellum. Extending into the suprasellar fossa 1 case is located outside the cerebellar fossa of posterior cranial fossa. 1 case HPC is located in the paracentral lobule. 12 cases have deep lobular change. 8 cases have multiple cystic changes around the lesion and 9 cases have multiple cystic degeneration. 11 cases are adjacent to dural sac. 11 cases are adjacent to dural sac. 9 cases were adjacent to dura mater with narrow base and 2 cases were adjacent to dura mater with wide base. The tumor was soft, red or gray-red, abundant in blood supply, some of the tumors had capsule, and most of the tumors had thin vessel vim positive staining and VEM negative. Conclusion: for intracranial and extracranial tumors adjacent to dura mater, the possibility of intracranial HPC should be taken into account when the tumor is adjacent to the dura with a narrow base and a deep lobular margin.
