Dyke-Davidoff-Masson syndrome in an 8-year-old child: Report of a case

Dyke-Davidoff-Masson syndrome (DDMS) is a rare entity. Few cases have been described in the literature. It can be symptomatic or asymptomatic. The clinical signs are very varied. Imaging is the key to diagnosis. Calvarial thickening, enlargement sinus, and cerebral hemiatrophy are suggestive signs. It is a cause of cerebral hemiatrophy and epilepsy. We report the clinical and radiological signs of this syndrome through a case of an 8-year-old male child treated for epilepsy. The importance of our article is to report a case diagnosed at an early age (8 years). Most studies report cases diagnosed in adults. MRI revealed pathognomonic signs of Dyke-Davidoff-Masson syndrome.
