Multifocal motor neuropathy (MMN) is the one of the most common acquired immune-mediated inflammatory disorders of the peripheral nervous system. The diagnosis is based on the distribution pattern of the neurological semiology and the pathological changes of nerve conduction studies (NCS) in classical cases. However, in cases with subtle clinical presentation, an extended diagnostic workup may be needed, such as cerebrospinal fluid examination, laboratory tests, and nerve biopsy. NCS remain nowadays fundamental not only for the diagnosis, but also for the follow-up and measurement of response to immune-treatment in MMN. New challenges arose though, on how best to acquire a static and dynamic imaging of the peripheral nerves, aiming to provide a holistic approach to the nerve impairment. According to the literature, neuromuscular ultrasound is able to detect in MMN patients thickened or swollen cervical roots, peripheral nerves or brachial plexus, findings that suggest ongoing inflammation. This review provides a timely update on the nerve ultrasound findings in MMN.。
