title: Headache as a sole manifestation in nonconvulsive status epilepticus.
abstract: Nonconvulsive status epilepticus can present with several manifestations, many of which might not be obvious. The most important for the diagnosis of nonconvulsive status epilepticus is the electroencephalogram (EEG) pattern. This is a case report of a 9-year-old boy with severe and continuous headache. He received chemotherapy for histiocytosis and was diagnosed at 3.5 years. He had no evidence of central nervous system histiocytosis involvement or drug toxicity. He was diagnosed with nonconvulsive status epilepticus. Headache and EEG anomaly disappeared completely when anticonvulsant therapy was begun. Headache and seizure disorder can coexist, but this might be the first report of nonconvulsive status epilepticus with headache as a sole manifestation.
