title: Reversible postictal MRI change mimicking structural lesion.
abstract: A reversible change on magnetic resonance imaging (MRI) following generalised seizure mimicking a tumour-like structural lesion is reported in a 15-year-old patient. MRI revealed a left fronto-parietal cortico-subcortical lesion on T2 weighted images. The control MRI after 5 weeks from the onset revealed no pathological finding. The reversible MRI changes may be the result of a local brain swelling, and a defect of cerebral autoregulation during seizure at the site of activity. The transient nature of such neuroradiological findings have to be taken into consideration in the differential diagnosis because of their similar appearance on imaging to intrinsic brain tumours.
