Résumé

We report imaging findings during, between, and after 2 stroke-like episodes in a 45-year-old woman with mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes (MELAS) syndrome with an A32243G mitochondrial mutation 6 years before. In November 2010, for a first episode, she showed mixed aphasia with logorrhea, disinhibition, agitation, euphoria, and a large left temporoparietal lesion. Symptomatology progressively regressed under L-arginine treatment. She was readmitted in June 2011 for a second episode with great anxiety, disorientation, impaired face recognition, worsening mixed aphasia, and a new right temporal lesion. After additional L-carnitine treatment, she remained without relapse for 14 months.
