A 39-year-old man with cerebello-tonsillar haemangioblastoma is presented,with emphasis on its morphological and imaging features. Although both computed tomography and cerebral angiography are very useful imaging modalities in helping to establish a radiological diagnosis, magnetic resonance (MR) imaging is more accurate and sensitive in depicting the lesion nature and extent. MR imaging is especially reliable in detecting multiple and other associated lesions within the central nervous system, such that a conclusive diagnosis of the von Hippel-Lindau syndrome can be made in selected cases. It is important to identify isolated haemangioblastomas as they constitute a relatively high percentage of benign resectable tumours within the posterior fossa.The differential diagnosis and imaging features of other posterior fossa tumours are also discussed.
本文报道了一名39岁患有小脑扁桃体血管母细胞瘤的男性患者，重点介绍了其形态学和影像学特征。虽然计算机断层扫描和脑血管造影在帮助建立放射学诊断方面都是非常有用的成像方式，但磁共振（MR）成像在描述病变性质和范围方面更准确、更敏感。MR成像在检测中枢神经系统内的多个及其他相关病变方面尤其可靠，以至于在某些病例中可以做出明确的冯·希佩尔-林道综合征诊断。识别孤立性血管母细胞瘤很重要，因为它们在小脑后窝内的良性可切除肿瘤中占比较高。本文还讨论了其他小脑后窝肿瘤的鉴别诊断和影像学特征。
