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.
