Abstract:
Multifocal motor neuropathy with conduction block (MMN) is characterized by a slowly progressive, asymmetrical weakness of the limbs without sensory loss. A differential diagnosis from other motor neuropathies has become increasingly important as MMN has proven to be a treatable disorder. We present a 45-year-old man with longstanding weakness and atrophy of the hand muscles. Electrophysiological studies revealed a typical conduction block in the bilateral median and ulnar nerves. A cycle of intravenous immunoglobulin treatment apparently did not affect the symptoms.
