Diverticulum of the lateral ventricle causing cerebellar ataxia. Case report

A case of ventricular diverticulum causing cerebellar ataxia is presented. Computerized tomography clearly demonstrated the aperture of the diverticulum in the medial wall of the trigone and its extension into the posterior fossa. The diverticulum regressed and the cerebellar ataxia disappeared after placement of a ventriculoperitoneal shunt.
