Axonotmesis of the femoral and sciatic nerves mimicking lumbar radiculopathy

We report a case describing an extraspinal cause of lumbosacral radiculopathy. The goal of this case report is to highlight the contributing role of magnetic resonance imaging (MRI) of peripheral nerves in radicular pain. Axonotmesis of the sciatic nerve could be considered as a post-traumatic piriformis syndrome.
