An unusual presentation of Dyke-Davidoff Masson syndrome.

Dyke Davidoff- Masson syndrome is a rare disorder of hemiatrophy of the cerebral hemisphere and clinically manifests as hemiparesis, seizures disorder, mental retardation and facial asymmetry and has various perinatal or post natal etiologies and has characteristic radiological appearance on brain imaging. It is important to recognize the clinical and radiological features of this condition for the neurologists as well as the radiologists. We are discussing our case as this patient presented very late although his symptoms seem to present since his birth which is very unusual with this disorder.
