Complex Partial Seizure-Induced Transient MR Enhancement J Comput Assist Tomogr 16:814-816, Horowitz,S.W.,et al, 1992 See this aricle in Pubmed Article Abstract A 58-year-old man with complex partial seizures had transient symmetrical MR enhancement in the anterior mesiotemporal cortex bilaterally,correlated with the sites of seizure focus on electroencephalography.Preinfused T1- weighted and T2-weighted sequences showed no abnormality.After adequate control of seizures with medication,repeat MR was normal and the prior enhancement was no longer seen.This transient seizure-induced MR enhancement was consistent with ictal or postictal hyperemia and breakdown of the blood-brain barrier and should not be erroneously attributed to mesial temporal sclerosis,encephalitis,tumor,or infarction.
