ABSTRACT
INTRODUCTION AND IMPORTANCE A pituitary abscess (PA) is an extremely rare disease. It is characterized by the presence of an infected purulent collection within the Sella turcica. PAs are categorized in two categories primary, when the pituitary is normal before the infection, or secondary, when there is a pre-existing sellar pathology (e.g., pituitary adenoma, Rathke's cleft cysts, or craniopharyngioma), meningitis, paranasal sinusitis, or head surgery, which may be indicative of the source of infection. CASE PRESENTATION We presented a case of a 52-year-old male with visual disturbances. Both a computerized tomography scan and magnetic resonance imaging revealed a sellar mass lesion, initially suspected to be a pituitary tumor. During transsphenoidal surgery for excision of the pituitary mass, an amount of pus was drained, indicating a pituitary abscess, which was confirmed by positive Staphylococcus aureus colonies in the culture. After surgery, the patient received antibiotic treatment for 12 weeks. After two years of follow-up, the patient remained free of complications and did not require hormone replacement therapy. CLINICAL DISCUSSION:
In previous research, there were a total of 488 patients, of those, 318 were primary pituitary abscess. Preoperative diagnosis is still difficult due to a combination of nonspecific symptoms and imaging findings. Endonasal trans-sphenoidal pus evacuation, culture, and individualized antibiotic therapy are available treatment options.CONCLUSION:
Pituitary abscess is a rare illness, but it should always be considered when evaluating a patient with a fast visual decline. Following the diagnosis, surgery and antibiotics should be started immediately. Proper therapy usually yields a positive effect.
