Rathke’s cleft cyst abscess from Klebsiella

Abstract

Pituitary abscesses are uncommon lesions accounting for <1% of all pituitary diseases. We report a case of a female microbiology technician with a rare congenital heart disease who developed an Rathke’s Cleft Cyst abscess from Klebsiella. A 26-year-old female biotechnician with a history of congenital heart disease and subclinical immunosuppression presented with a 10-month history of weight loss, amenorrhea, and visual deterioration. There was a history of previous unsuccessful transsphenoidal surgery. Radiology revealed a cystic lesion in the sellar region. The patient underwent an endoscopic endonasal intervention and the cystic cavity was washed with gentamicin, and the patient received meropenem postoperatively. The patient was followed up and had gradual improvement in her overall health, complete normality of her menstrual cycle, her visual field recovering to near normal and improving, no recurrence, and a stable cyst on magnetic resonance imaging.
