The diagnosis of central nervous system hemangioblastoma as well as the surgical treatment requires the accurate radiologic visualization of both the cystic and solid components of the tumor. We report two cases of posterior fossa hemangioblastoma examined with gadolinium-diethylenetriaminepentaacetic acid-enhanced magnetic resonance imaging, which clearly defined the tumor nodule that was not visualized on noncontrast magnetic resonance imaging, contrast-enhanced computed tomography scans, or angiography. In both cases the operative findings precisely correlated with the gadolinium-enhanced magnetic resonance image. Gadolinium-enhanced magnetic resonance imaging is the examination of choice for preoperative evaluation of posterior fossa hemangioblastoma. In cases of von Hippel-Lindau syndrome, magnetic resonance imaging is a useful tool for clinical screening as well as follow-up.
中枢神经系统血管母细胞瘤的诊断以及手术治疗需要对肿瘤的囊性和实性成分进行准确的放射学显影。我们报告两例后颅窝血管母细胞瘤病例，采用钆-二乙烯三胺五乙酸增强磁共振成像进行检查，该检查清晰地显示出在非增强磁共振成像、增强计算机断层扫描或血管造影中未显影的肿瘤结节。在这两例病例中，手术所见与钆增强磁共振图像精确相符。钆增强磁共振成像对于后颅窝血管母细胞瘤的术前评估而言是首选检查方法。对于冯·希佩尔-林道综合征病例，磁共振成像对于临床筛查以及随访都是一种有用的工具。
