| Differential: | cauda equina syndrome |
Saddle anesthesia is a loss of sensation (anesthesia) restricted to the area of the buttocks, perineum and inner surfaces of the thighs.
Asymmetric saddle anesthesia is frequently associated with the spine-related injury cauda equina syndrome.[1] It is also seen symmetrically with conus medullaris and may occur as a temporary side effect of a sacral extradural injection.[2]
