We report on a case of a 80-year-old man who developed progressive drowsiness with headache, fever and signs of meningeal irritation 2 days after a head trauma. Suspecting an infective meningoencephalitis, the patient was treated with wide spectrum antibiotic and antiviral therapy. Brain CT scan revealed a previously unknown pituitary expansive lesion. A brain MRI study confirmed the presence of an intrasellar lesion, which presented remarkable contrast ring enhancement, and showed non-specific inflammatory tissue on the clivus, possibly responsible of the clinical features of sterile meningitis. A biopsy proven diagnosis of pituitary apoplexy was made. This case highlights MRI as an important investigation for earlier recognition of pituitary apoplexy that can present with a clinical picture resembling an infective meningoencephalitis.
