Rare Predisposition For Acute Sports-related Nerve Injury In A Pediatric Patient - Page #3

Lab Studies: N/A Other Studies: To diagnose the location of the injury, a nerve conduction study and an electromyography study were ordered. Notably, initial limb temperatures were measured and within normal limits. Her motor nerve conduction study revealed prolonged distal latencies in the left ulnar nerve. Her sensory nerve conduction study revealed evidence of predominately demyelinating sensory physiology demonstrated by prolonged peak latencies in multiple nerves (left median, left ulnar, right median, and right dorsal cutaneous nerves) Case Photo #4 Case Photo #5 . Her electromyography study demonstrated evidence of muscle function abnormalities predominately in the left serratus anterior muscle, including increased insertional activity with positive sharp waves, increased fasciculations, and polyphasic and prolonged motor unit action potentials Case Photo #6 . In summary, her nerve conduction study revealed evidence of acute long thoracic nerve injury. In addition, it revealed evidence of previously unfound predominately sensory demyelinating physiology demonstrated by prolonged peak latencies in her left median, left ulnar, right median, and right dorsal cutaneous nerves suggestive of an underlying autoimmune or hereditary physiology.
