Metastatic epidural spinal cord compression (MESCC) occurs when cancer metastasises to the spine or epidural space and causes secondary compression of the spinal cord. MESCC is a common complication of malignancy that affects almost 5% of patients with cancer. The most common symptom is back pain. MESCC is a medical emergency that needs rapid diagnosis and treatment if permanent paralysis is to be prevented: the diagnosis of MESCC is best made with MRI; and corticosteroids, radiation therapy, and surgery are all established treatments. Future research will focus on prevention, improving detection, and the development of new treatments.
