Radiculopathy due to neoplastic disease is caused by the growth of a tumor in or near the spine. The tumor can press on the nerve roots, resulting in inflammation, swelling and irritation of the nerves which can cause pain, numbness and muscle weakness.
Diagnosis of radiculopathy due to neoplastic disease is made based on patient history, physical examination, imaging studies (such as MRI or CT scan) and possibly a nerve conduction study.
Differential diagnosis of radiculopathy due to neoplastic disease includes herniated disc, nerve root entrapment, spinal stenosis, diabetes, multiple sclerosis, and other neuromuscular disorders.
Treatment of radiculopathy due to neoplastic disease includes surgery to remove the tumor and the surrounding tissue, radiation therapy to shrink the tumor, and medications to reduce inflammation and pain.
The prognosis of radiculopathy due to neoplastic disease is generally good when the tumor is successfully removed and the patient receives appropriate treatment. However, if the tumor is not removed or treated, the prognosis can be poor.
