Dyke–Davidoff–Masson syndrome with crossed cerebellar atrophy

Dyke–Davidoff–Masson syndrome is a rare condition with classical, clinical and radiological changes – mental retardation, hemiparesis, facial asymmetry, seizures and cerebral hemiatrophy with calvarial changes. Contralateral cerebellar atrophy is rare and occurs if insult occurs after 1 month of age. We report a case of a 6-year-old female child presenting with right-sided hemiparesis, convulsions and left cerebral hemiatrophy with an old infarct in left middle cerebral artery (MCA) territory, ipsilateral calvarial thickening and right (crossed) cerebellar atrophy
