MELAS exhibiting multiple mass enhancement and dural enhancement: Case report

MELAS is maternally-inherited encephalomyopathy, characterized by seizures, migrainous headaches, lactic acidosis, vomiting, and recurrent stroke-like episodes. The strokes are affecting mainly the cerebral cortex and can be visualized by MRI. Most of the reported cases in the literature present with no enhancement or slight enhancement on MRI enhanced scan, but exhibiting multiple nodular enhancement and dural enhancement has never been reported. We here report a case of MELAS with multiple nodular enhancement and dural enhancement inside the brain on enhanced MRI.
