Question

which patient presentation is most consistent with cauda equina syndrome (ces)?
unilateral leg pain, numbness in the l5 dermatome, and reduced ankle reflex
bilateral leg pain worse with walking, relieved by sitting, and neurogenic claudication
severe lower back pain, saddle anesthesia, and urinary retention
chronic low back pain with intermittent paresthesia in both legs

Explanation:

Cauda Equina Syndrome is a neurological emergency caused by compression of the cauda equina nerve roots. Key hallmark symptoms include severe lower back pain, saddle anesthesia (numbness in the groin/perineal area like a saddle), and bladder/bowel dysfunction such as urinary retention. The other options describe symptoms of radiculopathy, neurogenic claudication, or chronic low back pain which do not match the specific presentation of CES.

Answer:

Severe lower back pain, saddle anesthesia, and urinary retention
