This evidenced a significant lumbar vertebral mass that showed tight canal stenosis and compression of the cauda equina. The patient was sent to the emergency department for management by orthopaedic surgeons. He was mobilising independently, pain free on arrival and without neurological deficit on assessment. Clinically, this patient presented with no red flag symptoms of cauda equina syndrome or reason to suspect malignancy. In these circumstances, National Institute for Health and Care Excellence guidelines do not support radiological investigation of the spine outside of specialist services. However, in this case, investigation helped deliver urgent care for cancer that otherwise may have been delayed. This leads to the question, do the current guidelines meet clinical requirements?
