Abstract：Objective To explore the diagnostic criteria, misdiagnosis causes and preventive measures of mitochon-drial myopathy, encephalopathy, lactic acidosis and stroke-like episodes ( MELAS) . Methods Clinical data of the MELAS patient misdiagnosed as cerebral infarct was retrospectively analyzed. Results The patient with double eyes vision loss for a day was hospitalized, and diagnosed as cerebral infarction after the body and head MRI examinations, vision of double eyes were mildly better after treatment. By DSA, MRS examinations and genetic testing, the patient was eventually confirmed as MELAS syndrome in stead of cerebral infarction. After 3-month treatment such as improving the metabolism and blood supply of the brain, the patient got better obviously, and MRI showed that the focus of head disappeared. Conclusion Clinical mani-festations being similar to acute cerebral infarction, head MRI showing cerebral infarction and knowledge of doctors being nar-row were the main causes of misdiagnosis. Strengthening learning to understand and mastering relevant knowledge of mitochon-dria encephalo-myopathy can prevent or reduce the misdiagnosis.
