| 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77～154Hu ,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 study the clinical and CT characteristics of solid hemangioblastoma in the posterior fossa and
improve the diagnostic rate. Methods A retrospective analysis of the clinical and CT manifestations in 32 patients with sol-
id hemangioblastoma in the posterior fossa was conducted. The diagnosis and differential diagnosis were discussed. Results
Diagnosis rate by radiologists preoperatively was 3/ 32. The CT tipical feature is a isodensity occupation with nonenhance-
ment and a marked hyperdensity occupation with contrast enhancement in the posterior fossa in the adults. CT value was 77
～154Hu. The vessels supplied to tumor were revealed in 8 patients. There was non or slight edema in the peritumor zone.
Conclusion The diagnosis of solid hemangioblastoma of the posterior fossa by CT scan must refer to the clinical manifesta-
tion of the patient . |
