A Rare Case of Dyke-Davidoff-Masson Syndrome in an Adolescent Female.

The Dyke-Davidoff-Masson syndrome (DDMS) is an uncommon neurological disorder whose prevalence is not yet known. There have only been 21 adult manifestations of this rare brain disorder, out of around 100 cases previously documented. Diagnosis is challenging because of the complexity of radiological findings and clinical symptoms, which include ventricle dilation, hypertrophy of the cranial bones, increased pneumatization of the sinuses, and cerebral hemisphere atrophy. It can be inherited or acquired from infections, brain hemorrhage, and hypoxia during pregnancy. Usually, neuroimaging is used to diagnose it. This case study reports the case of a 17-year-old girl who had complex partial seizures at the age of 17 and right-side paralysis since she was three years old.
