Abbreviations
- Brachial plexus (BP) schwannoma
Synonyms
- Peripheral nerve sheath tumor
- Neurilemmoma, neurinoma, or neuroma
Definitions
- Benign Schwann cell neoplasm that arises from BP in perivertebral space (PVS)
- PVS is cylindrical space surrounding vertebral column bound by deep layer of deep cervical fascia (DL-DCF)
- Subdivided at level of transverse processes into anterior prevertebral and posterior paraspinal components
