Abstract: The contribution of MR in 10 patients with surgically proven intracranial hemangioblastomas was retrospectively evaluated and correlated with the computed tomographic findings. Angiography was obtained in eight cases. Multiple lesions were shown in only two patients, but none proved to have von Hippel-Lindau disease. In six patients the tumor typically appeared as a cystic lesion with an intensely enhancing mural nodule at the pial surface of the cyst; three patients presented with a solid lesion with a central cyst and one with a solid lesion only. Thirteen tumors were located in the posterior fossa, with one in the brain stem extending towards the spinal cord. A supratentorial localization was found in two patients. Abnormal serpiginous vessels supplying or draining the mural nodule or solid lesion were not visualized on contrast-enhanced computed tomography, but were easily identified as flow voids on MR in five patients. Calcification or hemorrhage were not seen in the entire series. Because of the multiplanar imaging capability and the lack of streak artifacts from the petrous bone, MR provides better localization than CT. MR is more accurate in predicting the number, extension and vascularity of hemangioblastomas, and provides a sound basis for further diagnostic and therapeutic procedures.
