Moyamoya disease-the culprit in a young adult presenting with seizures: a case report

Moyamoya disease (MMD) is a rare, progressive cerebrovascular disorder characterised by narrowing the internal carotid artery (ICA) branches and forming fragile, abnormal collateral vessels. Patients with this condition often present with symptoms of cerebral ischemia or haemorrhage, and the disease typically follows a progressive course. Moyamoya derives its roots from Japanese literature meaning cloud or haze. Here we discuss a 23-year-old male who presented to the emergency with the chief complaint of a new-onset single episode of generalized tonic-clonic seizure. On further evaluation found to have MMD and cerebral revascularisation led to a favourable outcome.
