Introduction: In the context of pituitary adenoma, bacterial meningitis is a possible complication of surgical or medical treatment. The occurrence of meningitis before any treatment is exceptional, explained by the existence of an osteomeningeal breach caused by the adenoma whose main symptom is rhinorrhea. Case Report: We report a case of bacterial meningitis complicating a prolactin pituitary macroadenoma. The patient had been referred for jet vomiting in a febrile context preceded by headaches and visual blurring. There was no rhinorrhea. The examination revealed a meningeal syndrome and the diagnosis of acute bacterial meningitis was made. The isolated germ was the pneumococcus. Faced with headaches and visual blurring, a cerebral scan revealed a pituitary macroadenoma and pituitary hormone dosage had shown hyperprolactinemia. The meningitis was sterilized and the prolactinoma was treated with dopaminergic agonists. This allowed the normalization of prolactinemia and the disappearance of symptoms. Conclusion: The pituitary adenoma was complicated by bacterial meningitis without treatment and the presence of a meningeal breach. Hormonal and bacterial treatments have been successful.
