Variants in the EMD gene cause an X-linked recessive form (EDMD1). The scarce EDMD1 muscle MRI accounts in the literature describe fatty replacement of posterior thigh and leg muscles.<\/jats:p>\n                  <jats:p>We report a 22-year-old patient with early-onset bilateral joint contractures, slowly progressive muscle weakness and minor cardiac rhythm abnormalities. A novel loss-of-function variant of EMD was identified and deemed probably pathogenic in the absence of emerin detection by immunofluorescence and Western Blot. MRI revealed fatty replacement of the lumbar spinal erectors and the posterior compartment of lower limbs. Interestingly, Short Tau Inversion Recovery (STIR) sequences showed a heterogenous hyper signal on the vasti, hamstrings and left lateral gastrocnemius muscles.<\/jats:p>\n                  <jats:p>Oedema-like abnormalities were previously reported in early stages of other muscular dystrophies, preceding fatty replacement and muscle atrophy, but not in EDMD1 patients. We hypothesize that these oedema-like changes may be a marker of early muscle pathology in EDMD1. Further studies focusing on these abnormalities in the early phase of EDMD1 are required to test our hypothesis.<\/jats:p>","DOI":"10.3233\/jnd-220823","type":"journal-article","created":{"date-parts":[[2022,8,23]],"date-time":"2022-08-23T11:42:54Z","timestamp":1661254974000},"page":"649-654","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["Muscle MRI as a Diagnostic Challenge in Emery-Dreifuss Muscular Dystrophy"],"prefix":"10.1177","volume":"9","author":[{"given":"Maria Jo\u00e3o","family":"Pinto","sequence":"first","affiliation":[{"name":"Department of Neurology, Centro Hospitalar Universit\u00e1rio de S\u00e3o Jo\u00e3o, E.P.E., Porto, Portugal"},{"name":"Department of Clinical Neurosciences and Mental Health, Faculty of Medicine, University of Porto, Porto, Portugal"}]},{"given":"Yves","family":"Fromes","sequence":"additional","affiliation":[{"name":"Nuclear Magnetic Resonance Laboratory, Neuromuscular Investigation Center, Institute of Myology, Piti\u00e9-Salp\u00eatri\u00e8re Hospital, Paris, France"},{"name":"Nuclear Magnetic Resonance Laboratory, CEA, DRF, IBFJ, Molecular Imaging Research Center, Paris, France"}]},{"given":"Isabelle","family":"Ackermann-Bonan","sequence":"additional","affiliation":[{"name":"Nuclear Magnetic Resonance Laboratory, Neuromuscular Investigation Center, Institute of Myology, Piti\u00e9-Salp\u00eatri\u00e8re Hospital, Paris, France"},{"name":"Nuclear Magnetic Resonance Laboratory, CEA, DRF, IBFJ, Molecular Imaging Research Center, Paris, France"}]},{"given":"France","family":"Leturcq","sequence":"additional","affiliation":[{"name":"Department of Genomic Medicine and Systemic Diseases, APHP, University of Paris, Cochin Hospital, Paris, France"}]},{"given":"Camille","family":"Verebi","sequence":"additional","affiliation":[{"name":"Department of Genomic Medicine and Systemic Diseases, APHP, University of Paris, Cochin Hospital, Paris, France"}]},{"given":"Norma B.","family":"Romero","sequence":"additional","affiliation":[{"name":"Reference Center for Neuromuscular Disorders, APHP, Myology Institute, Piti\u00e9-Salp\u00eatri\u00e8re Hospital, Paris, France"},{"name":"Centre de Recherche en Myologie, GH Piti\u00e9-Salp\u00eatri\u00e8re, Sorbonne Universit\u00e9-Inserm UMRS974, Paris, France"},{"name":"Neuromuscular Morphology Unit, Institute of Myology, Piti\u00e9-Salp\u00eatri\u00e8re Hospital, Paris, France"}]},{"given":"Tanya","family":"Stojkovic","sequence":"additional","affiliation":[{"name":"Reference Center for Neuromuscular Disorders, APHP, Myology Institute, Piti\u00e9-Salp\u00eatri\u00e8re Hospital, Paris, France"},{"name":"Centre de Recherche en Myologie, GH Piti\u00e9-Salp\u00eatri\u00e8re, Sorbonne Universit\u00e9-Inserm UMRS974, Paris, France"}]}],"member":"179","published-online":{"date-parts":[[2022,8,22]]},"reference":[{"key":"ref001","doi-asserted-by":"publisher","DOI":"10.1002\/mus.26782"},{"key":"ref002","doi-asserted-by":"publisher","DOI":"10.1016\/j.nmd.2019.06.009"},{"key":"ref003","unstructured":"BonneG, LeturcqF, Yaou BenR.
