Which sign is most indicative of cauda equina syndrome requiring urgent referral?

• A. Saddle anesthesia and urinary retention or incontinence
• B. Headache
• C. Dizziness
• D. Chest pain

Answer: (A)

Recognizing red flags of cauda equina syndrome is essential because it’s a neurosurgical emergency. Saddle anesthesia, which is numbness in the buttocks, perineum, and inner thighs, shows involvement of the sacral nerve roots that supply the bladder and bowel. When you add urinary retention or incontinence, it signals autonomic dysfunction from compression of the cauda equina. This combination points to true cauda equina syndrome and warrants urgent referral for rapid imaging and possible decompression to prevent permanent deficits. Other signs like headache, dizziness, or chest pain do not reflect cauda equina involvement and aren’t the red flags seen with this condition.
