Intrasellar schwannomas are rare tumors that can mimic pituitary adenomas. This case highlights the importance of considering schwannoma in the differential diagnosis for sellar masses.

Area of Science:

  • Neuro-oncology
  • Endocrinology
  • Neurosurgery

Background:

  • Intracranial schwannomas typically originate from the eighth cranial nerve.
  • Schwannomas in the sella extending to the suprasellar region are exceptionally rare, often misdiagnosed as pituitary adenomas.
  • Only 12 prior reports of this specific tumor location exist.

Observation:

  • A patient presented with a primary intrasellar schwannoma.
  • Clinically and radiologically, the tumor resembled a pituitary adenoma.
  • Intraoperative findings revealed a firmer tumor consistency compared to a typical pituitary adenoma.

Findings:

  • The intrasellar schwannoma was successfully excised via a transethmosphenoidal approach.
  • Post-operative improvement in visual acuity and visual fields was observed.

  • Literature review confirmed the rarity and described characteristics of these lesions.

    • Implications:

    • This case underscores the diagnostic challenge posed by intrasellar schwannomas.
    • Early and accurate diagnosis is crucial for appropriate surgical management.
    • Consideration of schwannoma in the differential diagnosis of sellar masses is warranted.
