GARCIA, Laura; GUGLIELMO, Romina  e  ILLA, Lisandro. MELAS syndrome: CT and MRI as a noninvasive diagnostic tool. Rev. argent. radiol. [online]. 2010, vol.74, n.4, pp.379-383. ISSN 1852-9992.

We report on a 16-year-old male with bilateral hypoacusia, myopathy and focal neurological disorder. Since 9-year-old, he showed muscle development deficiency with repeated episode of exercise in tolerance and viral myocarditis. After ruling out an infectious etiology, CT and MRI were performed and yielded positive data about basal ganglia and brain parenchyma. The patient's radiological and clinical findings suggested mitochondrial encephalopathy. Genetic testing confirmed the diagnosis of MELAS syndrome (lactic acidosis with mitochondrial encephalomyopathy and stroke-like events).
