Symptoms of conus medullaris lesions
What are the clinical signs of conus medullaris lesions?
Lesions at the base of the spinal cord result in an autonomous neurogenic bladder and paralysis of the muscles of the pelvic floor.
There is loss of voluntary control of the bladder because there is no awareness of fullness.
This results in urinary retention and secondary overflow incontinence.
Constipation, erectile dysfunction, and symmetric saddle anesthesia may also be present.
Pain is not a typical part of this condition (which differentiates it from the cauda equina syndrome) but may occur late in the course.
