Mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes (MELAS) uncommonly develops after the age of 40. We describe a patient with MELAS whose first strokelike episode presented at age 65, followed by two more episodes. The brain MR imaging for each stroke-like episode demonstrated hyperintense lesion in diffusion weighted image (DWI),and variable signal intensities in apparent diffusion coefficient (ADC) maps in temporo-parietal and occipital regions. We diagnosed the patient as MELAS with 3243A>G point mutation. | |||||
