Clinical question: Seizure, etiology seen? Signs and symptoms: Seizure. Pre and post enhanced brain MRI:Diffusion weighted images are negative.Examination demonstrates scattered tiny nonspecific foci of FLAIR hyperintensity only in the subcortical and periventricular white matter of the lateral cerebral hemispheres. Findings demonstrate no evidence of hemorrhagic changes or abnormal enhancement and considering patient's stated age of 61 could represent mild chronic nonhemorrhagic small vessel ischemic strokes.The anatomical morphology and the signal intensity of brain parenchyma otherwise remains within normal on all MRI sequences. Unremarkable cerebral cortex, cortical sulci, ventricular system, CSF spaces and myelination of the brain.There is no detectable abnormal parenchymal or meningeal enhancement.Unremarkable images through the orbits and calvarium without abnormal enhancement.All the paranasal sinuses and bilateral mastoid air cells and middle ear cavities demonstrate normal pneumatization signal pattern.
