Moyamoya disease (MMD) is a rare, chronic cerebrovascular disease affecting the cerebral arteries, leading to the development of unique collateral vessels. Few cases were reported from Saudi Arabia; however, the incidence rate is not well-defined. Hence, we present a case of a 13-month-old child who presented to the emergency room with first onset focal seizures with relatively unremarkable past medical and family history. Investigations were ordered accordingly including head computed tomography (CT) scan, brain magnetic resonance imaging (MRI), and cerebral angiogram, and he was diagnosed with MMD and considering a broader variety of differential diagnoses for seizures in children is highlighted in our case. Furthermore, considering their predominance in east Asian countries, it highlights a rare presentation in the middle eastern race.
