Summary
Intrasellar arachnoid cysts can recur after surgery. Long-term follow-up is crucial following surgical excision of these sellar lesions to monitor for recurrence and vision changes.
Area of Science:
- Neurosurgery
- Ophthalmology
- Endocrinology
Background:
- Intrasellar arachnoid cysts are rare cystic lesions in the pituitary region.
- Surgical management is typically indicated for symptomatic lesions causing visual disturbances or hormonal dysfunction.
Observation:
- A 48-year-old male presented with decreased visual acuity and superior bitemporal visual field defects.
- Initial imaging revealed an intrasellar cystic lesion, diagnosed as an arachnoid cyst.
- The cyst was excised via a transsphenoidal approach, with initial visual improvement.
Findings:
- The patient experienced recurrence of the intrasellar arachnoid cyst four years post-operatively, presenting with similar visual field defects.
- A second excision via craniotomy led to gradual improvement in visual acuity and visual fields.
- Histopathological analysis confirmed the diagnosis of intrasellar arachnoid cyst.
Implications:
- This case highlights the potential for recurrence of intrasellar arachnoid cysts even after surgical intervention.
- Long-term, vigilant follow-up is essential for patients undergoing excision of intrasellar arachnoid cysts to detect and manage recurrence promptly.
- Craniotomy may be a viable surgical option for recurrent intrasellar arachnoid cysts when transsphenoidal approaches are less suitable.
