Summary
This study reports an extremely rare spinal tanycytic ependymoma in a 58-year-old man, presenting with hand sensory disturbance and arm weakness. Surgical removal and aspiration of associated hematomyelia were performed.
Area of Science:
- Neuro-oncology
- Spinal Cord Pathology
Background:
- Ependymomas are glial tumors that arise from ependymal cells, commonly found in the brain and spinal cord.
- Spinal tanycytic ependymomas are a rare subtype, often presenting with distinct clinical and radiological features.
Observation:
- A 58-year-old male presented with bilateral hand sensory disturbance and right arm weakness.
- MRI revealed a C2-C4 spinal cord tumor with associated hematomyelia.
- The tumor was soft, gelatinous, and subtotally resected; chronic liquid hematoma was aspirated.
Findings:
- Immunohistochemical and ultrastructural analyses confirmed the diagnosis of pure type spinal tanycytic ependymoma.
- The tumor's location and association with hematomyelia are key diagnostic indicators.
Implications:
- This case highlights the importance of considering rare spinal tumors in the differential diagnosis of myelopathy.
- Understanding the characteristics of tanycytic ependymomas aids in surgical planning and patient management.
- Further research into the pathogenesis and optimal treatment of these rare tumors is warranted.
