Neuro-Behçet's Disease With Coma.

Behçet's disease (BD) is a multisystemic vasculitis condition with unknown pathophysiology. Its clinical manifestations include recurrent oral and genital ulcers, cutaneous lesions, and uveitis. The term neuro-Behçet's disease (NBD) refers to the predominant neurological involvement in BD. The management of NBD is based on the severity of symptoms and the existence of additional systemic signs. Glucocorticoids and disease-modifying drugs are used for the treatment of the disease. In this report, we present a case of neuro-Behçet's disease (NBD) that presented with coma and extensive neuroradiological abnormalities.

Moyamoya syndrome presenting in an adult with Down syndrome: A case report with a literature review.

Moyamoya disease is an unusual occlusive cerebrovascular condition commonly seen in children, marked by stenosis of the internal carotid artery and circle of Willis, causing, cerebral ischemia. Moyamoya syndrome is a Moyamoya-like arteriopathy with risk factors including autoimmune disorders, thyroid disease, sickle cell disease, or Down syndrome. Trisomy 21 is a genetic disorder consistent with specific physical and behavioral characteristics, with intellectual impairment. We describe a rare case of Moyamoya syndrome manifesting as ischemic stroke in an adult with Down syndrome.

Dyke-Davidoff-Masson syndrome: A case report with a literature review.

Dyke-Davidoff-Masson syndrome (DDMS) is an uncommon neurological disease defined as cerebral hemiatrophy with a contralateral motor deficit, facial asymmetry, and seizures. Classic imaging findings are cerebral hypoplasia, ventriculomegaly, paranasal sinus hyper-pneumatization, and compensatory osseous enlargement. The diagnosis of DDMS is based on the correlation between clinical and neuroimaging features. The management of DDMS is based on anticonvulsant medication with physiotherapy. We describe an unusual case of DDMS presented with frequent and persistent seizures.
