Radiating leg pain usually originates from the spine; thus, the evaluation of the spine is usually recommended as the first diagnostic method when patients with such symptom visit the clinic. Sometimes, the patients continue to complain of radiating leg pain despite undergoing a spine operation, and it was found that the pain did not originate from the spine. The Spine center referred a male patient with radiating leg pain for a transformational epidural block. His spine MRI revealed a moderate spinal stenosis at the L3/4, L4/5 space. Although the block was tried once, it failed to relieve the symptoms, which raised doubts regarding the focus of pain. Using other radiologic evaluation, a suspicious cancerous mass was found on the left femur. Histological examination revealed that the mass depicted renal cell carcinoma. Despite receiving treatment, including chemotherapy, the patient subsequently died. Thus, based on these findings, it was concluded that radiating leg pain can be caused by both spinal and extraspinal lesions.
