However, it mimics conus medullaris syndrome, causing leg paresis and sensory loss involving the affected nerve roots (often in the saddle area), as well as bladder, bowel, and pudendal dysfunction. Similar deficits, especially if . . There are six basic types of ISCS based on clinical findings: (a) central cord syndrome (CCS), (b) Brown-Squard syndrome, (c) ventral (anterior) cord syndrome (VCS), (d) dorsal (posterior) cord syndrome (DCS), (e) cauda equina syndrome (CES), and (f) conus medullaris syndrome (CMS) ( 1, 3 ). iatrogenic. The conus medullaris is the terminal end of the spinal cord, which typically occurs at the L1 vertebral level in the average adult.

L2-sacrum. The anatomical variation in conus medullaris termination and the theoretical possibility of occult tethered cord syndrome make it difficult to consider an abnormal caudal position of the conus medullaris as a reliable diagnostic criterion in dogs .
