Gliomatosis cerebri with formation of a glioblastoma multiform. Study and follow-up by magnetic resonance and computed tomography.

A case of gliomatosis cerebri studied by computed tomography (CT) and magnetic resonance imaging (MRI) is reported. Follow-up by serial CT revealed a right parieto-occipital glioblastoma. Gliomatosis cerebri and multiform glioblastoma were demonstrated by histologic study. Anatomic and CT data were correlated. The role of CT and MRI in the diagnosis of this disease was evaluated and case studies of CT published in the literature were reviewed.
