Abstract: A chronic, occlusive cerebrovascular illness known as Moya Moya, sometimes known as “hazy puff of smoke,” involves bilateral stenosis or occlusion of the proximal sections of the anterior cerebral arteries and Middle Cerebral Arteries (MCAs) as well as the terminal portion of the Internal Carotid Arteries (ICAs). The internal carotid artery becomes progressively occluded and stenotic in Moya Moya, an idiopathic illness. A 34 year old woman with a known case of Moya Moya disease has been admitted to the hospital with the same complaints of weakness in the right and lower limbs. CT Angiography showed a significant narrowing of bilateral internal carotid favoring multivessel intracranial vascular disease and right hemiparesis. She had undergone STA MCA surgery previously in June 2021. Now as she admits with the similar complaints she was posted again for STA MCA surgery in May 2022 where she showed a positive outcome post surgery. Moya Moya disease management is still not well-defined and is based on unique methods. In this patient Moya Moya disease is recurring which may make the patient prone to strokes incase of severe narrowing of arteries which may be life threatening. In order to stop more stroke episodes from occurring and to enhance outcomes, adult patients with Moya Moya disease require careful, long-term neurologic and radiologic follow-up.
