Summary

Intrasellar arachnoid cysts, rare benign brain malformations, can extend upwards. Endoscopic surgery offers a good prognosis for these cysts, though recurrences are possible.

Area of Science:

  • Neurosurgery
  • Neurology
  • Radiology

Background:

  • Intrasellar arachnoid cysts are rare, benign malformations of the sellar region.
  • Their exact pathophysiology remains poorly understood.
  • These cysts account for approximately 3% of sellar region masses.

Observation:

  • A rare case of intrasellar arachnoid cyst with suprasellar extension is presented.
  • The cyst's features were analyzed epidemiologically, clinically, pathophysiologically, radiologically, and therapeutically.
  • Neuroendoscopic techniques are increasingly utilized in surgical interventions.

Findings:

  • Endoscopic transsphenoidal fenestration was the chosen treatment modality.
  • The surgical approach demonstrated a good prognosis for the patient.
  • Recurrences of the cyst were noted to be frequent, even years post-treatment.

Implications:

  • This case highlights endoscopic transsphenoidal fenestration as an effective treatment for intrasellar arachnoid cysts with suprasellar extension.
  • Understanding the long-term behavior, including recurrence patterns, is crucial for patient management.
  • Further research into the pathophysiology may lead to improved treatment strategies.
