Incidental pituitary macroadenomas with suprasellar extension were found in five patients. Despite extension, none had visual field defects, leading to varied management strategies including surgery and conservative approaches.

Area of Science:

  • Neuroendocrinology
  • Neurosurgery
  • Radiology

Background:

  • Pituitary macroadenomas are tumors of the pituitary gland, often discovered incidentally.
  • Suprasellar extension is a common feature, potentially impacting surrounding structures.

Purpose of the Study:

  • To describe five cases of incidentally detected pituitary macroadenomas with suprasellar extension.
  • To discuss the management of these incidental findings.

Main Methods:

  • Case series of five patients with incidentally detected pituitary macroadenomas.
  • Computed tomography (CT) and X-ray imaging for detection.
  • Computed perimetry for visual field assessment.
  • Trans-sphenoidal surgery and conservative management.

Main Results:

  • All five patients had pituitary macroadenomas with suprasellar extension.
  • None of the patients exhibited visual field defects.
  • Management varied, with four undergoing surgery and one managed conservatively.
  • Conservative management included observation due to normal function and spontaneous tumor size decrease.

Conclusions:

  • Incidental pituitary macroadenomas with suprasellar extension may not always cause visual compromise.
  • Management should be individualized based on tumor characteristics, pituitary function, and visual status.
  • Conservative management can be a viable option in select cases.
