Abstract

In the World Health Organization (WHO) 2021 classification system of neuroma, tumors of the cranial nerve and paravertebral nerve are mentioned, which are: (1) Schwannoma); (2) Neurofibroma; (3) Perineurioma; (4) Hybrid nerve sheath tumours; (5) malignant melanotic nerve sheath tumor; (6) Malignat peripheral nerve sheath tumor; (7) Cauda equina, (formerly paraganglioma). Schwannoma is a benign tumor arising from a schwann cell and mainly occurs in the nerve sheath in the intramedullary, epidural region. Tumor structures may be solid or cystic (less common). Because the tumor usually arises from the area within the spinal canal, the tumor often causes widening of the junctional cleft and compresses the nerve root. CT scan, magnetic resonance imaging and tumor biopsy under CT guidance help confirm the diagnosis. Total tumor resection remains the treatment of choice despite the high recurrence rate. We report a case of posterior mediastinal nerve sheath tumor diagnosed and surgically treated at the National Lung Hospital. The literature review and approach will be discussed in the discussion section.
