This study explored nerve echotexture using ultrahigh-frequency ultrasound (UH-FUS) in 13 MMN patients (mean age 61.9 years, disease duration 147\u2009\u00b1\u2009105 months). NE was detected in 77%, preferentially involving median nerve, yet conduction blocks corresponded to NE in only 15%. Notably, 92% showed mixed\/hyperechoic echotexture, including three patients with normal CSA, suggesting microstructural remodeling beyond swelling. No hypoechoic nerves were observed, consistent with limited acute inflammation. Combining echogenicity with NE assessment may improve n-US sensitivity, especially in atypical MMN.<\/jats:p>","DOI":"10.1177\/22143602261426071","type":"journal-article","created":{"date-parts":[[2026,3,11]],"date-time":"2026-03-11T18:36:14Z","timestamp":1773254174000},"page":"1134-1139","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Not only cross-sectional area: Echogenicity matters in nerve ultrasound studies of patients with motor multifocal neuropathy"],"prefix":"10.1177","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3068-0356","authenticated-orcid":false,"given":"Simona","family":"Maccora","sequence":"first","affiliation":[{"name":"University of Palermo"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sabrina","family":"Sacconi","sequence":"additional","affiliation":[{"name":"University Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicolas","family":"Azulay","sequence":"additional","affiliation":[{"name":"C\u00f4te d'Azur University, Nice University Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mihai Bogdan","family":"Ioncea","sequence":"additional","affiliation":[{"name":"University Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andra","family":"Ezaru","sequence":"additional","affiliation":[{"name":"University Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michele","family":"Cavalli","sequence":"additional","affiliation":[{"name":"University Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luisa","family":"Villa","sequence":"additional","affiliation":[{"name":"University Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giulia","family":"Tammam","sequence":"additional","affiliation":[{"name":"University Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Charles","family":"Raffaelli","sequence":"additional","affiliation":[{"name":"C\u00f4te d'Azur University, Nice University Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Angela","family":"Puma","sequence":"additional","affiliation":[{"name":"University Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,3,4]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0165-5728(01)00266-1"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp-2019-321532"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-4598(200006)23:6<900::AID-MUS9>3.0.CO;2-Y"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.0b013e3181f0738e"},{"key":"e_1_3_3_6_2","first-page":"295","article-title":"European federation of neurological societies\/peripheral nerve society guideline on management of multifocal motor neuropathy","volume":"15","author":"Joint Task Force of the EFNS and the PNS","year":"2010","unstructured":"Joint Task Force of the EFNS and the PNS.
