摘　　要：目的分析多发性血管母细胞瘤的MRI表现。方法回顾性分析经病理证实的9例多发性血管母细胞瘤的MRI表现,总结其影像学特征。结果 9例血管母细胞瘤患者中,共发现63个病灶,其中后颅窝病灶51个(80.9%),椎管内病灶11个(17.5%),幕上病灶1个(1.6%)。根据影像学分型,大囊小结节型病灶15个(23.8%),实质型病灶43个(68.3%),单纯囊型病灶1个(1.6%),以上所有病灶增强扫描实性成分均呈明显强化。结论多发性血管母细胞瘤多发于后颅窝,影像学类型多为实质型,增强扫描呈显著强化,因此,多发性血管母细胞瘤MRI表现具有明显特征性,MRI对其诊断具有较大的临床价值。Objective To analyze the MRI features of multiple angioblastoma. Methods Analyzing MRI features of 9 patients’ multiple angioblastoma that confirmed by pathology retrospectively, and summarizeing their imaging features. Results Among the 9 patients with angioblastoma, 63 lesions were found totally, including 51 lesions(80.9%)in the posterior fossa, 11 lesions(17.5%) in the spinal canal, and 1 lesion(1.6%) in the supratentorial area. According to the imaging classification, 15 lesions(23.8%) were cysts with a mural nodule, 43 lesions(68.3%) were solid tumors, and 1 lesion(1.6%) was pure cyst, all the lesions were significantly enhanced by enhanced scanning. Conclusion Multiple angioblastoma occured mostly in the posterior fossa, most lesions were solid tumors, which is significantly enhanced by enhanced scanning. So it is typical for the MRI findings, herein MRI is of great clinical value in the diagnosis of multiple angioblastoma.
