title: Pain due to epidural tumor in cancer patients. Report of two cases and differential diagnosis.
abstract: The cases of two patients with inguinal pain as the only symptom of a T12 metastatic lesion is reported. The patterns of pain referrals from tumor lesions to the spine, epidural space, and spinal cord are reviewed. Focal back pain and pain reported in a distal distribution can both be associated with epidural or cord disease. The differential diagnosis of back pain in patients with cancer can be difficult but may be crucial in differentiating important neurological complications of systemic neoplasms.
