Abstract
- The preoptic area and anterior hypothalamus plays a pivotal role in body temperature regulation, and damage in this region causes hyperthermia. This hyperthermia is particularly troublesome because of the possibility that it may reflect an occult infectious process. We report a case of fever of unknown origin in a patient after removal of neoplasm involving the hypothalamus. A 29-year old man underwent craniotomy and removal of hypothalamic choroid meningioma. Seventy days after the removal of his tumor, his body temperature began to rise. But, there was no evidence of infection, inflammatory disease, metabolic disease, drug fever and recurred tumor. Repeated administration of antipyretic agent did not reduce body temperature. So, we considered that the elevated temperature had a central basis. The patient was treated with chlorpromazine in an attempt to lower his temperature. This drug reduced successfully his body temperature.
