Transsphenoidal surgery effectively treats symptomatic colloid cysts in the pituitary region. This safe procedure restores endocrine function and alleviates symptoms like menstrual irregularities and headaches in most patients.

Area of Science:

  • Neurosurgery
  • Endocrinology
  • Neuroradiology

Background:

  • Intra- and suprasellar non-neoplastic cysts, particularly colloid cysts, can cause significant endocrine and neurological symptoms.
  • Surgical intervention is often considered for symptomatic cases, but its efficacy and safety require evaluation.

Purpose of the Study:

  • To evaluate the outcomes of transsphenoidal surgery for symptomatic intra- and suprasellar colloid cysts.
  • To assess the impact of surgery on endocrine function and presenting symptoms.

Main Methods:

  • A retrospective review of 69 patients who underwent transsphenoidal surgery for symptomatic intra- and suprasellar non-neoplastic cysts over 11 years.
  • Detailed analysis of presenting symptoms, endocrine assessments, surgical findings, and postoperative outcomes.

Main Results:

  • Transsphenoidal surgery was performed on 18 patients with colloid cysts, frequently presenting with menstrual irregularities, galactorrhea, and headaches.
  • Postoperatively, significant improvements were observed in menstrual cycles (82%), headaches (80%), prolactin levels (92%), and galactorrhea (89%).
  • The procedure was generally safe, with only one case of diabetes insipidus and one of SIADH reported.

Conclusions:

  • Transsphenoidal surgery is a safe and effective treatment for symptomatic intra- and suprasellar colloid cysts.
  • The surgery is particularly beneficial for women of childbearing age, restoring fertility and preventing pituitary dysfunction.
  • Preoperative MRI findings, such as a non-enhancing mass between pituitary lobes, can suggest colloid cyst presence.
