A pituitary abscess caused secondary amenorrhea, polyuria, and polydipsia in a patient. Surgical drainage and antibiotics successfully treated the abscess, resolving symptoms and preventing recurrence.

Area of Science:

  • Endocrinology
  • Neurosurgery
  • Infectious Diseases

Background:

  • A 28-year-old woman presented with a year of amenorrhea, polyuria, polydipsia, fatigue, and weight loss.
  • Initial investigations revealed panhypopituitarism, diabetes insipidus, an intrasellar mass, and papilledema, suspected to be intracranial hypertension.

Purpose of the Study:

  • To report a case of pituitary abscess presenting with panhypopituitarism and diabetes insipidus.
  • To describe the diagnostic and management approach for this rare condition.

Main Methods:

  • Conservative management was initially attempted for the intrasellar mass.
  • Magnetic resonance imaging (MRI) revealed pituitary mass enlargement and optic nerve compression.
  • The pituitary abscess was surgically drained via a transsphenoidal approach, followed by antibiotic therapy.

Main Results:

  • The patient experienced resolution of symptoms following surgical drainage and antibiotic treatment.
  • Postoperative follow-up showed no recurrence of the pituitary abscess.
  • The transsphenoidal approach was effective in managing the pituitary abscess.

Conclusions:

  • Pituitary abscess is a rare but treatable cause of hypopituitarism and diabetes insipidus.
  • Early diagnosis and surgical intervention are crucial for favorable outcomes.
  • Antibiotic therapy is essential in preventing recurrence.
