摘要
目的 :探讨颅内血管外皮细胞瘤的CT诊断 ,提高对其认识和诊断水平。材料和方法 :分析颅内血管外皮细胞瘤患者 13例 ,经手术及病理证实 ,男 9例 ,女 4例 ,年龄 32～ 71岁。均行增强前、后的CT扫描。结果 :9例CT平扫为均匀高密度 ,增强扫描病变明显增强 ;4例CT平扫为不均匀混杂密度 ,增强扫描病变实性部分明显增强 ,囊变坏死部分无增强。病变大小为 3～ 15cm。结论 :颅内血管外皮细胞瘤与脑膜瘤的CT表现相似 ,但前者常无钙化、邻近骨质多为溶骨性破坏及增强表现有助于诊断。
Purpose: To investigate the CT features of intracranial hemangiopericytoma and improve its diagnostic accuracy. Materials and Methods: CT findings of 13 patients (9 males and 4 females, aged 32～71) of intracranial hemangiopericytoma proved by pathology were analysed. Unenhanced and contrast-enhanced CT scan were performed in all cases. Results: The lesions appeared homogeneous high density in 9 of 13 cases on plain CT scans and appeared obverious enhancement on enhanced CT scans. 4 of 13 cases appeared inhomogeneous density on plain CT scans and showed marked enhancement in solid parts of the lesions after enhancement but the necrotic parts showed no enhancement.The areas of lesions were about 3～15cm. Conclusion: The CT appearances of intracranial hemangiopericytomas are similar to meningiomas, except no calcification. The adjacent ossature transformed dissolved, and more obvious enhancement in intracranial hemangiopericytomas on CT that provide evidences to diagnosis of this tumor.
