Bacterial Meningitis as the Initial Presentation of Pituitary Macroadenoma

펼치기

Bacterial meningitis is an uncommon complication of pituitary macroadenoma. Bacterial meningitis can occur in patients with pituitary macroadenoma who have received sphenoidal surgery or had cerebrospinal fluid (CSF) rhinorrhea. A 62-year-old male visited our hospital for headache and fever. Brain magnetic resonance imaging showed a pituitary macroadenoma. CSF study revealed acute bacterial meningitis. Intravenous antibiotics and hydrocortisone replacement therapy were started, and lead to good clinical outcome. Bacterial meningitis should be considered in patients with a pituitary macroadenoma who present with meningitis symptoms, even though in the absence of rhinorrhea or surgical history.
