[Recurrent episodes of fever of unknown origin as temporal lobe epilepsy].

A 67-year-old woman was admitted to our department for the recurrent fever of unknown origin that occurred once approximately every 1 month for the last 3 years. No clinical and laboratory abnormality were found, except an interictal EEG showing fronto-temporal spike discharges. During hospitalization a characteristic febrile episode was accompanied by automatism, thereby, it became clear that the undetermined periodic febrile episodes were due to temporal lobe epilepsy. In this case, the thermoregulatory center of the hypothalamus might be symptomatic zone of temporal lobe epilepsy.
