[MRI aspects of cerebellar hemangioblastomas. Apropos of 9 cases].

Nine patients with haemangioblastoma of the posterior cerebral fossa were explored by computerized tomography (CT), then by magnetic resonance imaging (MRI) with enhancement by gadolinium in 4 cases. Following a review of clinical and laboratory data, the radiological images are detailed and distributed into three forms: cystic with mural nodule, solid, and annular. The usefulness of the different imaging techniques is specified, and the stress it put on the need to look for multiple sites in the entire central nervous system.
