[Cerebral gliomatosis. A report of three cases and review of the literature].

Introduction: Cerebral gliomatosis is an infiltrating, non destructive process of glial type, with a diffuse growth pattern and great clinical variation in the initial symptoms. Confirmation of the diagnosis requires histological study of the lesion showing infiltration by well differentiated mature astrocytes (atypical forms are rare). We report three cases diagnosed by our department over the past five years.
