Presentation of Dyke-Davidoff-Masson Syndrome in adult male.

Dyk-Davidoff-Masson Syndrome (DDMS) is one of the rare neurological conditions attributed to the development of drug-resistant epilepsy (DRE). The DDMS condition is characterized by cerebral hemisphere asymmetry, where atrophy occurs on one side of the brain and clinically manifests as hemiparesis, seizure disorder, mental retardation, and facial asymmetry. In addition, the condition has various perinatal or postnatal etiologies. Herein, we report the case of a 29-year-old right-handed male with Dyke-Davidoff Masson syndrome and mild right-side weakness. The patient experiences attacks of seizures with stiffness in his right arm and right leg, sometimes experiencing agitation and abnormal movement of the body parts. The MRI of the brain showed asymmetry with atrophic changes involving the left hippocampus, consisting of mesial temporal sclerosis. Additionally, the results showed the presence of gyral hyperintensities over the left parietal region. Therefore, the patient's case is reported with a literature review to support it.
