    Area of Science:

    • Endocrinology
    • Neurosurgery
    • Infectious Diseases

    Background:

    • Pituitary abscesses are rare but serious infections affecting the pituitary gland.
    • Intrasellar masses can present with diverse neurological and endocrine symptoms.

    Observation:

    • A 16-year-old female presented with amenorrhea, polyuria, polydipsia, and severe headaches.
    • Pneumoencephalography revealed an intrasellar mass.
    • Surgical exploration via a transsphenoidal route identified purulent material within the sella turcica.

    Findings:

    • The intrasellar mass was diagnosed as an encapsulated pituitary abscess.
    • The patient experienced anterior and posterior pituitary hypofunction postoperatively.
    • Hormonal replacement therapy was initiated for pituitary insufficiency.

    Implications:

    • Early diagnosis and surgical intervention are crucial for managing pituitary abscesses.
    • Pituitary abscesses can lead to significant endocrine dysfunction requiring long-term management.
    • This case highlights the importance of considering infectious etiologies for intrasellar masses.
