Summary
This study reports a rare case of primary mediastinal ependymoma in an adult female, successfully treated with thoracoscopic surgery. This finding contributes to the limited understanding of this uncommon spinal tumor.
Area of Science:
- Neurosurgery
- Thoracic Surgery
- Oncology
Background:
- Primary mediastinal ependymoma is an exceedingly rare tumor.
- Ependymomas typically arise within the central nervous system.
Observation:
- A 50-year-old female presented with back pain and a paravertebral posterior mediastinal mass.
- Computed tomography revealed a 3.4 x 1.0 cm spindle-shaped mass at the Th 3-4 level.
- Histological and immunohistochemical examination confirmed the diagnosis of ependymoma.
Findings:
- The tumor, a cystic mass with a solid component, was completely resected via thoracoscopic surgery.
- No invasion into surrounding tissues was observed.
- The patient remained alive 59 months post-resection, with no recurrence.
Implications:
- This case expands the known spectrum of ependymoma presentation.
- Highlights the importance of considering rare diagnoses in mediastinal masses.
- Suggests complete resection as an effective treatment strategy for primary mediastinal ependymoma.
