Dyke-Davidoff-Masson syndrome.

Abstract

A 21-year-old man presented with seizures, behavioral changes and\nleft-sided hemiparesis. There was history of encephalitis at one year\nof age. Physical examination showed hemiatrophy of the left side of the\nbody with spastic hemiparesis. There were incomplete achievement of\nmental milestones. Computed Tomographic (CT) scan of brain revealed\natrophy of the right cerebral hemisphere with sparing of the basal\nganglia.Midline structures were shifted by the intact cerebral\nhemisphere and skull vault thickening and prominent frontal sinus were\nnoted (Figure 1a, 1b). Magnetic Resonance (MR) imaging demonstrated the\ngray-white matter loss with hyperintensities on T2 weighted images and\nasymmetry of the basal ganglia (Figure 2).
