Reversible MRI changes in prolonged status epilepticus: a case report.

MRI is an essential investigation in epilepsy and status epilepticus (SE) for determining the underlying cause. However, SE or prolonged seizures may themselves induce changes in the MRI resulting in difficulty in interpretation. This case report illustrates a patient who recovered completely from prolonged generalized idiopathic SE lasting more than 2 weeks and had transient bilateral external capsule, fronto-temporal, and insular cortical MRI changes. The mechanism of such MRI changes and their implications for survival even after prolonged SE are discussed.
