Summary
A rare solitary plasmacytoma in the sphenoid bone mimicked a pituitary adenoma. Surgical removal and radiotherapy were successful, with no signs of recurrence or multiple myeloma two years later.
Area of Science:
- Neuro-oncology
- Endocrinology
- Pathology
Background:
- Solitary plasmacytoma is a rare plasma cell neoplasm.
- Sphenoid bone involvement is uncommon.
- Differential diagnosis with pituitary adenoma is crucial for appropriate management.
Observation:
- A case presented with symptoms suggestive of a pituitary adenoma.
- Imaging revealed a lesion in the sphenoid sinus.
- The patient did not exhibit signs of systemic multiple myeloma.
Findings:
- Histopathological examination confirmed solitary plasmacytoma of the sphenoid.
- The tumor was completely resected via a trans-sphenoidal approach.
- Post-operative radiotherapy was administered.
Implications:
- This case highlights the importance of considering rare tumors in the differential diagnosis of sellar/parasellar masses.
- Successful management of sphenoid solitary plasmacytoma is achievable with combined surgical and radiation therapy.
- Long-term surveillance is necessary to rule out progression to multiple myeloma.
