Seven patients with histologically confirmed cerebellar hemangioblastomas are reviewed in order to establish computed tomographic (CT), angiographic and clinical characteristics and correlations. Noncontrast CT scans demonstrated most cystic lesions but did not always depict nodules on the cyst wall and small solid tumors. Contrast-enhanced CT scans demonstrated the solid and cystic types of tumors but in some cases angiography better delineated them and the presence of nodules. The CT appearance reflected the pathologic characteristics, which included vascular channels, cyst formation and nodules. Solid tumors enhanced homogeneously and could not be definitively distinguished from other cerebellar neoplasms by CT alone. One atypical undifferentiated tumor appeared as a solid mass with a necrotic center. The CT appearance of associated retinal angiomatosis is also described. Hydrocephalus, gait or appendicular ataxia was the initial clinical presentation in these patients.
回顾了7例经组织学确诊的小脑成血管细胞瘤患者，以确定计算机断层扫描（CT）、血管造影及临床特征和相关性。平扫CT扫描显示了大多数囊性病变，但并不总能显示囊肿壁上的结节和小实性肿瘤。增强CT扫描显示了实性和囊性肿瘤类型，但在某些情况下，血管造影能更好地显示它们以及结节的存在。CT表现反映了病理特征，包括血管通道、囊肿形成和结节。实性肿瘤呈均匀强化，仅靠CT不能明确与其他小脑肿瘤区分开来。1例非典型未分化肿瘤表现为有坏死中心的实性肿块。还描述了相关视网膜血管瘤病的CT表现。脑积水、步态或肢体共济失调是这些患者的初始临床表现。
