“…In contrast to some previous studies that included patients with longer disease duration , we found no gadolinium contrast enhancement. This is in agreement with more recent reports that noted its limited sensitivity in CIDP . In contrast, albuminocytologic dissociation was a frequent finding and may be a more sensitive marker that indicates blood–nerve barrier dysfunction.…”

“…40,42 MRI is required to detect the enlargement in the lumbosacral plexus and very proximal sciatic nerve. [43][44][45][46] In addition to enlargement, nerves in CIDP can have increased vascularization, increased echogenicity, and fascicular enlargement or loss of the normal fascicular appearance. 10,34 In contrast, patients with axonal polyneuropathies usually show no or only minimal nerve enlargement outside of common sites of entrapment.…”

“…Ultrasound evaluation of the lower extremity is less informative than evaluation of the upper limb in CIDP . MRI is required to detect the enlargement in the lumbosacral plexus and very proximal sciatic nerve . In addition to enlargement, nerves in CIDP can have increased vascularization, increased echogenicity, and fascicular enlargement or loss of the normal fascicular appearance .…”

Ultrasound can be used to visualize pathology in the peripheral nerves of patients with polyneuropathy. Nerve enlargement is the most frequent pathology, but other abnormalities, including abnormal nerve echogenicity and vascularity, are also encountered. This monograph presents an overview of the role of nerve ultrasound in the evaluation and management of both inherited and acquired polyneuropathies. A description of the sonographic techniques and common abnormalities is provided, followed by a presentation of typical findings in different neuropathies. Scoring systems for characterizing the presence and pattern of nerve abnormalities as they relate to different polyneuropathies are presented. Muscle Nerve 57: 716-728, 2018.

“…These findings were improved by IVIG. In CIDP, including MADSAM, hyperintensity with or without hypertrophy of the cervical spinal roots and/or brachial plexus appears on the affected side . Details of MRI abnormalities in MMN, however, are currently insufficient for reliable MRI‐based diagnosis .…”

Herein we report the case of a 6-year-old girl with autism spectrum disorder (ASD) and weakness in the distal portion of the right upper limb. Although difficult to perform, nerve conduction studies indicated demyelinating neuropathy. Magnetic resonance imaging (MRI) showed swelling a nd high-intensity signals in the right brachial plexus and cervical spinal roots. The symptoms recovered after a single course of i.v. immunoglobulin. Electrophysiological indices and MRI findings also improved after treatment. This case demonstrates the utility of neuroimaging in addition to electrophysiological assessments for the diagnosis of demyelinating neuropathy, particularly in young patients with ASD.
