Background:
The presentation of a thoracic spinal tumor due to high-impact trauma is quite rare and we found no other case reported.
Case Description:
This is a case report and literature review. A patient presented with severe paraparesis on day 4 after trauma. Thoracic MRI showed an oval image centered to T4-T5 suggestive of hemorrhage. The patient underwent a bilateral T4 and T5 laminectomy and microsurgically assisted intradural exploration. After laminectomy, we found no extradural lesions, so we proceeded to dural opening, after which we found a large extramedullary lesion which was completely removed. Pathology revealed a schwannoma. The patient had a very good recovery after surgery and motor rehabilitation. At 6 months after surgery, inferior limbs muscle strength was completely normal. We found no other case reported.
Conclusion:
Thoracic spine schwannomas are difficult to early diagnose unless there is a clinical suspicion. Initial presentation as bleeding after trauma was not described before. This presentation should be kept in the differential diagnosis of any patient with an acute neurological deficit without trauma signs on admission imaging.
