ABSTRACT

A 30-year-old woman experienced nasal stuffiness followed by a progressive headache and reduced visual acuity for 3 weeks. She underwent an endoscopic endonasal transsphenoidal approach (EETA) for pituitary spindle cell oncocytoma 13 months before the present admission. Magnetic resonance imaging (MRI) revealed an intrasellar cystic lesion with a suprasellar extension. After EETA for tumor removal, the histological findings of inflammatory infiltration showed a pituitary abscess. Microscopy revealed mites and fungal hyphae. Cultures from the abscess showed Staphylococcus hyicus, Stenotrophomonas maltophilia, and Aspergillus sp. The patient received a 6-week antibiotic treatment, which completely resolved the clinical symptoms and cleared the MRI findings.
