目的:探讨血管母细胞瘤的影像诊断。材料与方法:回顾性分析 35例经手术病理证实的血管母细胞瘤的 CT和 MRI表现,分析肿瘤的影像特点。结果:多数肿瘤(80%),为囊性,表现为脑脊液样密度或信号,囊壁上附有小结节,增强扫描呈明显均一强化。 MR较 CT更易发现小结节。少数(20%)表现为实质性肿块,部分合并囊变。结论: CT和 MRI是诊断血管母细胞瘤的有效方法,对囊性肿瘤可作定性诊断。
Objective: To investigate the imaging diagnosis of hemangioblastoma. Materials and Methods: A retrospective analysis of 35 cases of pathologically confirmed hemangioblastoma CT and MRI manifestations, the imaging features of the tumor. Results: Most of the tumors (80%) were cystic. They showed cerebrospinal fluid density or signal. Small nodules were attached to the wall of the cysts. The contrast enhancement was obviously enhanced. MR is easier to detect than nodules. A minority (20%) showed substantial mass, partial consolidation of cystic degeneration. Conclusion: CT and MRI are effective methods for the diagnosis of hemangioblastoma, which can be used as a qualitative diagnosis of cystic tumors.
