Summary
This study reports a rare ectopic clival craniopharyngioma, a tumor separate from the sella turcica. An endonasal endoscopic approach successfully removed the lesion with minimal invasiveness.
Area of Science:
- Neurosurgery
- Endocrinology
- Pathology
Background:
- Craniopharyngiomas are typically located in the sellar region, arising from remnants of Rathke's pouch.
- Ectopic craniopharyngiomas, particularly those in the clival region and separate from the sella turcica, are exceptionally rare.
Observation:
- A 44-year-old woman presented with abducens palsy, indicating neurological compromise.
- Imaging (MRI and CT) revealed a cystic clival lesion distinct from the sella turcica.
Findings:
- Surgical resection was successfully achieved using a flexible endoscope-assisted endonasal transsphenoidal approach.
- Radiological, intra-operative, and clinical assessments confirmed no involvement of the sellar region.
- A literature review identified no similar reported cases of ectopic clival craniopharyngioma.
Implications:
- This case highlights the possibility of ectopic craniopharyngiomas arising from aberrant Rathke's pouch remnants.
- The endonasal transsphenoidal endoscopic approach offers a minimally invasive and effective surgical option for select clival lesions.
- Further research into the embryological origins and optimal surgical management of ectopic craniopharyngiomas is warranted.
