The spectrum of peri-ictal MRI changes; four illustrative cases


Kramer et al first described transient MRI abnormalities in a patient with focal status epilepticus in 1987 [1]. Since then, increased use and availability of MRI has revealed a wide spectrum of neuroimaging abnormalities in the acuteictal period. The appearance of these abnormalities can sometimes pose diagnostic dilemmas for clinicians who may encounter them in a variety of clinical scenarios and are unsure about their significance. Abnormalities may be focal and concordant with the site of seizure focus or remote from the ictal onset zone [2].
