Complex partial status epilepticus of extratemporal origin in a patient with systemic lupus erythematosus.

The purpose of this case report is to describe the clinical, electroencephalographic and neuroimaging findings from a woman with systemic lupus erythematosus presenting with complex partial status epilepticus (CPSE) of neocortical temporo-parieto-occipital origin. The patient experienced complex visual hallucinations that initially were attributed to treatment with corticosteroids; however, an electroencephalogram (EEG) demonstrated the epileptic aetiology of her symptoms. CPSE should be considered as a possible cause of altered mental status in lupus. An urgent EEG is essential to make an accurate diagnosis.
