Cauda Equina Syndrome

Cauda equina syndrome is presented as a rare but time-critical spinal emergency that can be difficult to recognise because early symptoms often resemble ordinary musculoskeletal back pain. The teaching explains why clinicians must keep serious pathology in mind, even when symptoms appear to improve, and why repeated reassessment over time is essential. Key areas include the anatomy of the cauda equina, common causes such as large central disc prolapse and spinal stenosis, and the main symptom groups: back or leg pain, saddle sensory change, bladder and bowel dysfunction, and sexual dysfunction. Particular emphasis is placed on the fact that classic textbook presentations are uncommon, so incomplete or evolving cases can be easily missed. The lecture also covers practical questioning, especially how to explore bladder, bowel, saddle, and sexual symptoms clearly and without jargon. It highlights diagnostic uncertainty, the limited reliability of clinical examination alone, and the importance of a low threshold for urgent MRI when suspicion is present. Learners can also expect discussion of bilateral sciatica, safety-netting, documentation, referral pathways, and the wider clinical responsibility to identify non-benign causes of pain early.
