目的探讨颅内血管外皮细胞瘤(HPC)的影像表现,提高影像学认知水平。方法回顾性分析7例HPC的影像学特点,并结合文献进行复习。结果 HPC好发于硬脑膜附近,广基底与其相连。类圆形、分叶形或不规则形脑外占位性病变,界清,等T1、等T2信号或混杂信号,可伴有囊变、坏死,周围有流空血管影及水肿,增强扫描明显强化。结论 HPC的MRI表现具有一定特异性,结合多种检查方法有助于提高其诊断水平。
Objective To investigate the imaging manifestations of intracranial hemangiopericytoma (HPC) and to improve the imaging knowledge. Methods The imaging characteristics of 7 cases of HPC were retrospectively analyzed and reviewed with the literature. Results HPC occurs in the vicinity of the dura, broad base connected to it. Class round, lobulated or irregular shape of extraparenchymal lesions, such as clear, such as T1, T2 signal or mixed signals, may be associated with cystic degeneration, necrosis, around the empty blood vessels and edema, enhanced scan Significantly strengthened. Conclusion The MRI findings of HPC have a certain specificity. Combined with a variety of examination methods can help to improve the diagnosis of HPC.
