Prolonged absence status epilepticus associated with carbamazepine therapy, increased intracranial pressure, and transient MRI abnormalities.

We describe an adolescent epileptic patient who presented in nonconvulsive status epilepticus that appeared to be related to treatment with carbamazepine. The absence status, which was resistant to multiple anticonvulsants, produced increased intracranial pressure and transient abnormalities observed on MRI.
