A 54 year old man visits his physician for evaluation of low back pain. He has a history of lung cancer and he receives a combination of radiation and chemotherapy. His back pain started 3 months ago and now he complains of numbness and tingling in his lower limbs.
What is the most likely cause of this patient’s back pain?
A- Paraneoplastic disease
B- Metastases to the vertebral column
C- Muscular spasm of paravertebral muscles
