title: Invasive pituitary adenoma with abscess formation: case report.
abstract: A case is presented and 10 cases are reviewed in which abscess formation developed in an intrasellar tumor. The diagnosis was made preoperatively or before autopsy in only 1 patient. The mortality rate was greater than 50%. The most common presentation was headache, fever, and visual disturbances with an abnormal sella and sterile cerebrospinal fluid (CSF). Nonconstant findings included meningeal signs and leukocytosis of the CSF. Trans-sphenoidal removal of the tumor and drainage of the abscess with appropriate antibiotic therapy is recommended. (Neurosurgery, 5: 718--722, 1979).
