%X Mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes (MELAS) is caused by mutations in mitochondrial DNA and is one of the most common syndromes among the mitochondrial diseases. Clinical manifestations typically occur before the age of 40 years. The present study reports a case of MELAS with a mutation in the adenine to guanine conversion at mitochondrial genome 3243 in a 48-year-old woman who was suspected of suffering from recurrent strokes. Finally, the genomic analysis confirmed the diagnosis of MELAS. This case highlights the importance of considering MELAS as a potential cause of recurrent stroke-like events if imaging findings are atypical for cerebral infarction, even among middle-aged patients with vascular risk factors.
