Summary
This study reports a rare intrasellar arachnoid cyst case, highlighting its diagnosis and successful surgical treatment. The findings emphasize the cyst
Area of Science:
- Neurosurgery
- Neurology
- Radiology
Background:
- Intrasellar arachnoid cysts are exceedingly rare sellar region masses.
- Differentiating them from other sellar lesions like pituitary adenomas is crucial.
Observation:
- A 58-year-old male presented with visual disturbances, optic atrophy, and bitemporal hemianopsia.
- Radiological imaging (CT, angiography, pneumoencephalography) revealed a cystic lesion in the intrasellar and suprasellar regions.
- Surgical exploration via a transsphenoidal approach confirmed an arachnoid cyst.
Findings:
- Histological examination confirmed the cyst wall composed of arachnoid membrane.
- Surgical management led to improvement in visual symptoms.
- Cerebrospinal fluid rhinorrhea occurred postoperatively but resolved spontaneously.
Implications:
- Intrasellar arachnoid cysts present diagnostic challenges due to overlapping features with common sellar tumors.
- The transsphenoidal approach is a viable surgical option for managing these rare cysts.
- Early diagnosis and appropriate surgical intervention can lead to favorable patient outcomes.
