Lennox-Gastaut syndrome and computerized axial tomography findings.

Computerized axial tomography (CAT) in 38 patients with Lennox-Gastaut syndrome showed normal findings in 20 patients and abnormalities in 18; diffuse cerebral atrophy (8) was the most common abnormality. These findings are not basically different from those recently reported by Gastaut and Gastaut (1976). Emphasis is laid upon age and possible increase of diffuse abnormalities with advancing age. The observation of 2 cases with cerebellar atrophy is also discussed.
