Abstract

Mitochondrial encephalomyopathy with lactic acid and stroke-like episodes (MELAS) is a multisystem mitochondrial disorder that is rarely observed in adulthood. We report a case of MELAS syndrome diagnosed in a 22-year-old man presented with status epilepticus (SE) without a preceding stroke-like episode. Genetic testing revealed a mutation of heteroplasmic m.3243A>G. MELAS should be suspected in patients with recurrent, uncontrolled SE with unexplained severe lactic acidosis.
