Introduction
Spinal synovial sarcoma (SS) is an extremely rare malignant tumor in children.
Case report
We report an unusual pediatric synovial sarcoma located in the thoracic spine at T9–T10 levels. A 10-year-old boy was admitted with a 1-month history of progressive back pain and low fever for 7 days as well as sudden onset of paraplegia for 1 day. The primary diagnosis was considered for spinal inflammatory abscess; subsequently, the patient underwent total resection with a good recovery and confirmed SS by SYT-SSX gene translocation.
Conclusion
The possibility of sudden paraplegia caused by unusual SS involved in the spine should be highlighted.
