目的　探讨颅后窝实体性血管网织细胞瘤临床和CT特点 ,分析CT误诊原因 ,以提高诊断率。方法　对手术及病理证实的 32例颅后窝实体性血管网织细胞瘤的临床及CT进行回顾性分析 ,并对其诊断及鉴别诊断进行讨论。结果　本组术前仅 3例诊为本病 ;本病典型表现为青壮年CT平扫为等密度 ,增强后明显强化的高密度不规则或分叶状团块占位影 ,CT值 77～ 1 54Hu ,8例显示肿瘤供应血管影 ,瘤周无或有轻度水肿。结论　颅后窝实体性血管网织细胞瘤的诊断必须注意CT影像与临床病史相结合 Objective To investigate the clinical features and CT features of posterior retrobulbar solid vascular hemangioblastoma and to analyze the causes of misdiagnosis of CT in order to improve the diagnostic rate. Methods The clinical and CT findings of 32 cases of posterior posterior vascular solid hemangiocytoma confirmed by surgery and pathology were retrospectively analyzed. The diagnosis and differential diagnosis of the latter were discussed. Results This group only 3 cases diagnosed as the disease before surgery; typical manifestation of this disease in young adults CT scan for the same density, enhanced significantly enhanced after the high-density irregular or lobulated mass shadow, CT value of 77 ~ 1 54Hu, 8 cases showed tumor supply of blood vessels, no or mild peritumoral edema. Conclusion The posterior fossa retrolental solid hemangiocytoma must be diagnosed by combining the CT image with clinical history
