Abstract

Pituitary abscess is a rare condition. It can present with hormonal deficiencies and may affect reproductive health. We present a case of a 43-year-old female presenting with bitemporal hemianopsia and amenorrhea. Imaging of the pituitary showed a sellar-suprasellar mass 2.6 x 2.4 x 1.8 cm with an enhancing nodular component. Pre-operative diagnosis was pituitary adenoma with panhypopituitarism and compression of the optic chiasm. The patient underwent transsphenoidal excision of the tumor. Intraoperative findings revealed purulent fluid consistent with pituitary abscess. There was immediate improvement of vision post operatively. She did not develop diabetes insipidus. Gram stain showed polymorphonuclear (PMN) cells 0-1 per oil immersion field (OIF) and Gram-positive cocci 0-1 per OFI, however there was no growth on culture. The abscess was also negative for acid-fast bacilli and was negative on polymerase chain reaction. Histopathologic evaluation showed benign cyst contents. The patient was treated with ceftriaxone 2 grams every 12 hours for 14 days and was eventually discharged with prednisone and levothyroxine. Pituitary abscess is an important differential diagnosis for sellar and suprasellar masses. There are no specific clinical and radiologic features that will enable a
