摘　　要：目的:探讨后颅窝血管母细胞瘤MR影像特点,提高其影像诊断率。材料与方法:对本院2011-2013年间经手术病理证实的7例后颅窝血管母细胞瘤的MR资料进行回顾分析。结果:7例患者中男2例、女5例,6例单发,1例多发(系术后2年复发);4例位于小脑半球,2例位于四脑室,1例位于四叠体池;6例均呈类圆形大囊小结节型,1例以实性为主。MRI平扫发现囊性区均呈类似于脑脊液样信号影,且无强化,边缘结节呈明显强化。实性为主者,强化较明显。结论:后颅窝血管母细胞瘤多数呈大囊小结节样改变,壁结节呈血管样明显强化对诊断有一定的特异性。Purpose： To evaluate the MR imaging findings of hemangioblastomas in posterior cranial fossa, and improve the correct dignositic rate. Materials and Methods： We collect the clinical and imaging characteristics of 7 hemangio- blastomas in our hospital, retrospectively, from 2011 to 2013, which were all proved by histological findings. Results： Two of the 7 patients were male, 5 were female. All of the hemangioblastomas were solitary, except for one multiple lesions, which were recurrence after surgery in 2 years ago. Six of the neoplasmas were exclusively present with solitary well enhanced nodule with peritumoral or intratumoral cyst without any enhancement, the solid one were well enhanced. Conclusion： Most of the hemangioblastomas in posterior cranial fossa present with solitary or multiple nodules with peritumoral or intratumoral cyst, and the well enhanced nodules which mimic vessels is valuable to make correct diagnosis.
