A 17-year old girl presented with recurrent seizures, strokes, fatigue, vomiting, cerebellar ataxia, dementia and hypertrichosis. Further examinations showed jerking left-sided arm reflexes, partial internal deafness and myopathy. CT and MR of the skull revealed radiolucencies within the cerebral matter of the cortex and the medulla. Laboratory tests showed increased levels of lactate and pyruvate in serum and cerebro-spinal fluid. Microscopic examination of muscular tissue showed "ragged red fibers". Electron microscopy yielded crystal inclusions in mitochondria. The symptoms represented the complete picture of the so-called MELAS/MERRF-complex, which can be easily misdiagnosed as strokes and seizures of unknown cause.
