We describe a 58‐year‐old male with a few years history of multifocal weakness in the upper limbs with minimal to absent sensory complaints. He was diagnosed as having multiple compressive neuropathies, which required repeated decompressive surgeries. Electrodiagnostic studies prior to diagnosis were limited to a few nerves, evaluating only distal segments. Because of delay in making the diagnosis, his condition progressed, and possibly because of the unnecessary surgeries, he developed atrophy in some muscles, which resulted in significant motor disability. He was later diagnosed as having multifocal motor neuropathy with conduction block and has partially responded to intravenous immunoglobulin therapy. © 1998 John Wiley & Sons, Inc.
