Intradural, extramedullary tumors are for the most part either meningioma, schwannomas, and possibly ependymomas. While most intradural extramedullary tumors are benign, these tumors cause neurological damage by compressing on the spinal cord and nerve roots. Patients usually will need surgery and/or radiation.
Pain is an early symptom of intradural extramedullary tumors, however when these grow they result in compression the spinal cord and nerves. This causes:
- Localized spine pain
- Limb dysfunctions
- Loss of motor skills and sensations
- Bowel and bladder dysfunction
- Pain in back at night
- If compression is chronic, muscle wasting can occur along the affected nerve roots.
Diagnosis and Treatment
Patients with spinal intradural and extramedullary tumors require emergency diagnosis and treatment to reduce the pressure and preserve function as soon as possible. For the most part these tumors are aggressive and metastatic arising from lung, colon, breast, and prostate tumors.
