Summary
This case study details an uncommon infrasellar craniopharyngioma in a woman experiencing headache and double vision. Surgical removal via a transsphenoidal approach was successful, highlighting rare tumor presentation.
Area of Science:
- Neuro-oncology
- Endocrinology
- Otorhinolaryngology
Background:
- Craniopharyngiomas are rare tumors arising from remnants of Rathke's pouch.
- Infrasellar craniopharyngiomas, located below the sella turcica, represent a particularly uncommon subtype.
- These tumors can present with diverse and sometimes subtle clinical manifestations.
Observation:
- A 34-year-old woman presented with progressive headache and diplopia.
- Imaging revealed a heterogeneous tumor in the infrasellar region, extending into the sphenoid bone, ethmoid sinus, and sella turcica.
- The tumor's infrasellar origin and extensive local invasion were notable features.
Findings:
- A sublabial rhinoseptal transsphenoidal surgery was performed for tumor resection.
- Histopathological confirmation of craniopharyngioma was established.
- The case contributes to the limited literature on infrasellar craniopharyngiomas, with only 35 reported instances.
Implications:
- This case underscores the importance of considering rare tumor locations in the differential diagnosis of sellar and parasellar masses.
- Understanding the embryological basis and distinct radiological features of infrasellar craniopharyngiomas is crucial for timely diagnosis and appropriate surgical planning.
- Further research into the specific characteristics and management of this rare entity is warranted.
