The ulnar, sciatic, median, and radial nerves, along with the
lumbosacral plexus were most commonly injured as a result of GSWs, the brachial plexus as a result of MVAs, and the facial and accessory nerves secondary to iatrogenic causes, specifically complications of tumor-excision surgery (Figure 4).
MRI of the lumbosacral plexus is not diagnostic but is essential to exclude other causes of neuropathy such as nerve compression or transection.
Interestingly nerves outside the brachial plexus are more frequently affected and in 32.6% of the attacks the lumbosacral plexus is involved [4].
Sciatic neuropathy can be the result of any focal lesion of the nerve in the hip or thigh, distal to the
lumbosacral plexus but proximal to the separation of the nerve into its distal branches.
The lumbosacral plexus is formed by the last lumbar spinal nerve and the first two sacral spinal nerves (Dyce et al, 2010).
In a study of the morphology of the lumbosacral plexus of the ocelot (Leopardus pardalis), Lopes et al.
One might expect at some stage to see injury to the laterally located
lumbosacral plexus and ureters, although these are at least 4 to 5 cm away from the anterior-most point of the fifth lumbar vertebral body.
