目的:探讨颅内实质性血管母细胞瘤的CT、MRI特征,提高对颅内实质性血管母细胞瘤的诊断水平。方法:回顾性分析11例经手术和病理证实的颅内实质性血管母细胞瘤的CT、MRI表现及相关临床资料,全部病例均行CT、MRI平扫及增强。结果:11例患者肿瘤大小不等,呈实质性圆形或类圆形肿块。肿瘤位于大脑半球者5例(额叶3例,顶叶1例,颞叶1例),位于后颅窝者6例(小脑半球3例,小脑蚓部1例,延髓背侧1例,桥小脑角区1例)。CT平扫肿瘤呈稍低或等密度;MRI T1WI呈稍低或等信号,T2WI呈高或稍高信号,9例瘤内或瘤周可见多发血管流空信号影;增强扫描肿瘤呈均匀明显强化,增强扫描有助于病灶检出和定性诊断。结论:颅内实质性血管母细胞瘤的CT、MRI表现具有特征性,CT、MRI检查对颅内血管母细胞瘤的诊断具有重要价值。
Objective: To explore the CT and MRI features of intracranial hemangioblastoma and to improve the diagnosis of intracranial hemangioblastoma. Methods: The CT and MRI findings and related clinical data of 11 cases of intracranial hemangioblastoma confirmed by operation and pathology were retrospectively analyzed. All the cases underwent CT and MRI plain scan and enhancement. Results: The size of the tumors in 11 patients was of a substantially round or oval shape. The tumors were located in the hemisphere in 5 cases (3 cases of frontal lobe, 1 case of parietal lobe, 1 case of temporal lobe), and 6 cases of posterior fossa (3 cases of cerebellar hemisphere, 1 case of cerebellar vermis, 1 case of dorsal medulla oblongata, 1 case of cerebellar angle). CT scan was slightly lower or equal density of the tumor; MRI T1WI was slightly lower or equal signal, T2WI was high or slightly higher signal, 9 cases of tumor or peritoneal visible multi-vascular flow signal; enhanced scan was uniform and significantly enhanced , Enhanced scan helps to detect lesions and qualitative diagnosis. Conclusion: CT and MRI features of intracranial hemangioblastoma are characteristic. CT and MRI are of great value in the diagnosis of intracranial hemangioblastoma.
