RT Journal Article SR Electronic T1 Case of an atypical pituitary abscess JF BMJ Case Reports JO BMJ Case Reports FD BMJ Publishing Group Ltd SP e246776 DO 10.1136/bcr-2021-246776 VO 14 IS 11 A1 Zachary W Bloomer A1 Treyce S Knee A1 Zachary S Rubin A1 Thanh Duc Hoang YR 2021 UL http://casereports.bmj.com/content/14/11/e246776.abstract AB A pituitary abscess is a rare intrasellar infection. Correct identification can be challenging preoperatively given its non-specific symptoms and imaging findings. We report a case of a young woman presenting with secondary amenorrhea, visual field deficits and a 2.6 cm pituitary lesion diagnosed to be a craniopharyngioma. A concomitant unexpected pituitary abscess was diagnosed intraoperatively without associated meningeal symptoms.
