We present a magnetic resonance imaging of a 38 old woman, admitted with clinical symptoms of expansive cerebellar lesion. No mural nodule and no enhancement after gadolinium injection were noted. She was operated upon and an anatomico-pathological diagnosis of a simple cyst was made. Cysts of the posterior fossa are common in the literature, but the simple cyst is rare. Considered in the differential diagnosis of these cysts: (hemangioblastoma, astrocytoma cystic, hydatid cyst ...). The postoperative course was uneventful after surgery.
