P.058 Length dependent sensorimotor peripheral neuropathy often results in ventral abdominal sensory loss

Abstract

Background: Length-Dependent Sensorimotor Peripheral Neuropathy (LDSMPN) affects the longest nerve fi bers in the body. Less well-appreciated, and absent from the current literature, is that LDSMPN affecting thoracic segments gives rise to ventral abdominal sensory loss on clinical exam. Methods: Consecutive patients seen for LDSMPN (n=30) were evaluated prospectively for the presence or absence of ventral abdominal sensory loss. Demographic variables, symptoms, quantitative neurologic fi ndings (Neuropathy Impairment Score [NIS]) and fi nal diagnosis were examined using descriptive statistics. Background: Mononeuritis multiplex is a painful, asymmetrical peripheral neuropathy involving motor and sensory nerves. This neurological condition is classically associated with systemic diseases such as connective tissue disorders, vasculitis, hematologic diseases including cryoglobulinaemia and amyloidosis. It has also been reported infrequently as a paraneoplastic or post infectious disorder. Methods: Case report Results: We are reporting a case of a 35-yearold man who presented with mononeuritis multiplex following an infectious mononucleosis associated with a mixed cryoglobulinemia. He was treated with IVIG, IV pulse steroid and a prednisone taper over 7 months. Later on, he had a nerve transfer from FCR (fl exor carpi radialis) to ECRB (extensor carpi radialis brevis) and PIN (posterior interosseous nerve) due to complete denervation of the PIN without evidence of spontaneous recovery. Conclusions: Acute EBV infection should be suspected in the setting of mononeuritis multiplex. This is the fi rst reported case of nerve transfer for this type of nerve injury.
