Abstract

The presence seizure-induced signal changes on brain magnetic resonance imaging (MRI) have been increasingly recognized in the literature. The reversible MRI changes in epileptic patients may be the result of a local brain swelling, a defect of cerebral autoregulation and a blood-brain barrier disruption during sustained epileptogenic activity. We report a 62 years old man diagnosed with a subacute right parietal syndrome. MRI shows a tumefactive lesion in right temporo-occipital lobes mimicking a structural lesion. Electroencephalogram (EEG) exhibits continuous ictal activity in the same region. Antiepileptic drugs were started achieving progressive electro-clinical improvement. Subsequent MRI showed remission of signal changes.
