Abstract

Multifocal enlargements with the alteration of a normal fascicular pattern are considered to be sonographic peripheral nerve features in multifocal acquired demyelinating sensory and motor neuropathy (MADSAM), a subtype of chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). We herein present the case of an 18-year-old patient with MADSAM in whom intensive sonological assessments revealed multifocal nerve enlargement within clinically affected cranial nerves. Our case demonstrated that, if systematically investigated with ultrasound, morphological changes similar to those in the peripheral nerves may be detected in a large proportion of clinically affected cranial nerves in MADSAM, boosting the future applications of cranial nerve ultrasound in CIDP.
