Headache associated with focal brain edema in non-convulsive status epilepticus

摘要

We report a 27-year-old man who presented with a continuous headache, nausea, and lack of awareness after convulsive attacks. Electroencephalography showed rhythmic theta activity or generalized sharp-and-slow wave complexes that met EEG criteria for NCSE. A Magnetic resonance imaging study showed focal cortical edema in the mesial temporal lobes, anterior cingulate gyri, and frontal bases on both sides. Single photon emission tomography showed focal hyperperfusion of the left frontal and temporal lobes. Continuous electrical activity in those areas may underlie the patient's symptoms including headache and neuroimaging abnormalities.
