Pituitary abscess associated with prolactinoma.

We present a 37-year-old female, who was admitted with a long standing history of menstrual abnormalities and galactorrhoea followed by progressive visual loss. X-ray of the skull showed an enlarged sella with destruction of the floor. CT scan of the head revealed a giant pituitary adenoma with sellar and parasellar extension. At surgery, through a transsphenoidal approach, solid tissue and cystic areas containing pus from which Escherichia coli was cultured were encountered. She had an uneventful postoperative recovery. At 2 years follow up, she was doing well.
