目的：分析血管母细胞瘤的MR影像特点。材料与方法：9例（11个病灶）经病理证实的血管母细胞瘤，均行MR检查。结果：血管母细胞瘤的直接征象（如囊肿型的瘤结节，实质性、混合性肿瘤的实质部分明显强化；瘤内出现血管流空信号）及间接征象（肿瘤实质部分邻近软脑膜或与软脑膜有粘连）具有一定的特异性。结论：MR对诊断血管母细胞瘤具有较高的价值。
Objective: To analyze the characteristics of MR imaging of hemangioblastoma. Materials and Methods: Nine patients (11 lesions) with pathologically confirmed hemangioblastoma underwent MR examination. Results: The direct signs of hemangioblastoma, such as cystic tumor nodules, substantial enhancement of the substantial part of the mixed tumor, vasodilatory signs in the tumor, and indirect signs of tumor (the parenchyma of the tumor is adjacent to the pia mater or Pia mater adhesion) has a certain specificity. Conclusion: MR is of high value in the diagnosis of hemangioblastoma.
