CLINICAL CASE OF MOYAMOYA DISEASE IN A CHILD

The critical nature of Moyamoya disease poses a high risk of disability and potentially fatal outcomes in children, as it can result in ischemic or hemorrhagic strokes and may lead to recurrent strokes. The lack of effective conservative treatment necessitates early surgical correction of hereditary cerebral arteriopathy in children. Aim. To describe a clinical case of Moyamoya disease in a child presenting with ischemic stroke. Materials and Methods. Clinical, neurological, biochemical, and neuroimaging examination of the child. The results. A child with ischemic stroke was admitted for rehabilitation 5 months after the event. Multidetector computed tomography of the brain showed areas of malacia in the left parietal region resulting from arterial infarcts. Non-contrast magnetic resonance imaging of the brain showed significant narrowing of the left middle cerebral artery, with a reduction in its distal segments compared to the contralateral side. This led to the diagnosis of Moyamoya disease. Surgery was performed to create an extra-intracranial anastomosis using the external temporal artery. Six months after surgery, the child's motor function was fully recovered. Conclusions. Cerebral vascular disease in children requires careful differential diagnosis, including MMD. Early diagnosis and surgical treatment of Moyamoya disease can prevent adverse outcomes, disability, and even death in children.
