title: An unusual extraspinal cause of bilateral leg pain.
abstract: Low back pain with pain radiating to the lower extremities is common in patients referred to a spine center. Lumbar spine pathology is commonly the etiology of such symptoms, but extraspinal causes of back and leg pain can manifest as a radicular disorder. Extraspinal etiologies must be considered in the workup of back and leg pain. This report describes an unusual case of spontaneously occurring bilateral femoral neck stress fractures presenting as low back pain with seemingly bilateral L4 radicular symptoms.
