title: Complex partial seizure-induced transient MR enhancement.
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.
