Abstract: | Pituitary abscess is a rare disease, but one with potentially high mortality and morbidity. We present a 46-year-old man with progressive visual disturbance and general malaise for 1 year. Endocrine studies revealed hypopituitarism, and magnetic resonance imaging revealed a pituitary lesion with suprasellar extension. We attempted to excise the lesion using a transsphenoidal approach, but pus in the pituitary fossa was found at operation, and no tumour was identified. The culture yielded coagulase-negative Staphylococcus. Antibiotics were administered for 3 weeks, and the patient made a good postoperative recovery. He required life-long hormone replacement therapy. After one and a half years of follow-up, he was well and had no evidence of focal or systemic infection. We review the literature regarding pituitary abscess and discuss the appropriate treatment and possible pathological mechanism. |
