Mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes in a 69-year-old woman

摘要

The mitochondrial myopathies are an uncommon inheritable condition, with a diverse range of clinical presentations. Prognosis is generally poor, with death usual before the fifth decade of life. We present a case of mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes (MELAS), the most common clinical mitochondrial myopathy syndrome, presenting with generalized seizure in a previously undiagnosed 69-year-old woman. The clinical, radiographic and pathological features of this condition are briefly reviewed.
