In the current study, we investigated the utility of ultrasound pattern sub-score A (UPSA) and intra- and internerve cross-sectional area (CSA) variability in the diagnostic evaluation of demyelinating neuropathies. <i>Materials and Methods</i>: Nerve ultrasound was performed in patients with chronic inflammatory demyelinating polyneuropathy (CIDP) and acute inflammatory demyelinating polyneuropathy (AIDP) and compared to patients with axonal neuropathies. The UPSA, i.e., the sum of ultrasound scores at eight predefined measurement points in the median (forearm, elbow and mid-arm), ulnar (forearm and mid-arm), tibial (pMedicina (Kaunas, Lithuania)Nerve Ultrasound Score in Chronic Inflammatory Demyelinating Polyneuropathy.PMC10144993DOMRSF-2021-01Shahrizaila NTan CYGoh KJYahya MAfalseNerve Ultrasound Score in Chronic Inflammatory Demyelinating Polyneuropathy.<i>Background and Objectives</i>: Studies have suggested that, by applying certain nerve ultrasound scores, demyelinating and axonal polyneuropathies can be differentiated.
