Moyamoya disease is a cerebrovasculopathy of unknown etiology during the course of which the main and terminal veins of the internal carotid artery undergo progressive vein occlusion. Leigh syndrome is a mitochondrial encephalomyopathy that occurs due to "cytochrome c oxidase deficiency" characterized by psychomotor retardation, difficulty in eating, seizures, hypotonia, respiratory disorders and high lactate levels. Many diseases and syndromes have been defined that are associated with Moyamoya disease. To the best of our knowledge, the association of moyamoya disease with Leigh syndrome has not been defined as yet. In this study, the clinical and imaging results of a 3-year-old male child displaying the association of Moyamoya disease and Leigh syndrome are presented.

Brush sign (BS) was first reported as prominent hypointensity of deep medullary veins and subependymal veins on T2*-weighted images at 3 T MRI in patients with acute stroke in the territory of the middle cerebral artery. Subsequently, BS in central nervous system (CNS) diseases such as moyamoya disease, cerebral venous thrombosis, and Sturge-Weber syndrome was also described on susceptibility-weighted imaging (SWI), and the clinical implications of BS were discussed. The purpose of this review is to demonstrate BS on SWI in various CNS diseases and its mechanisms in the above-mentioned diseases.

Objective: Periventricular anastomosis (PA), a recently recognized cause of hemorrhage in moyamoya disease, is reducible after bypass surgery. The timing of the reduction, however, remains poorly understood. The objectives of the present study were to demonstrate radiological reduction of PA occurring within 48 hours after surgery and to identify factors associated with reduction.

Purpose: Moyamoya disease (MMD) is a rare cerebrovascular disorder characterized by the narrowing of arteries at the brain's base. While cerebral angiography is the gold standard for diagnosis, high-resolution vessel wall magnetic resonance imaging (VW-MRI) has recently emerged as a non-invasive diagnostic tool. This systematic review aims to provide insights into the role of VW-MRI in enhancing the diagnosis and management of MMD.
