Intrasellar tuberculoma, a rare condition, can mimic pituitary adenomas. Surgery revealed tuberculoma despite initial signs suggesting adenoma, highlighting diagnostic challenges in pituitary region lesions.

Area of Science:

  • Neuroendocrinology
  • Infectious Diseases
  • Pathology

Background:

  • Intrasellar tuberculoma is an uncommon manifestation of tuberculosis affecting the pituitary gland.
  • Pituitary adenomas are common sellar masses, often presenting with hormonal dysfunction or mass effect.

Observation:

  • A patient presented with clinical and radiological findings suggestive of a pituitary adenoma.
  • The sellar lesion exhibited features typically associated with secreting adenomas.

Findings:

  • Histopathological examination post-surgery definitively diagnosed the lesion as tuberculoma.
  • No specific clinico-radiological features were pathognomonic for intrasellar tuberculoma, complicating preoperative diagnosis.

Implications:

  • This case underscores the importance of considering infectious etiologies, like tuberculosis, in the differential diagnosis of sellar masses.
  • Accurate preoperative diagnosis of intrasellar tuberculoma remains challenging, necessitating a high index of suspicion.
