Rash preceded neurological symptoms in five patients; seizures were the initial manifestation in the remaining two. Seizures were the most common neurological symptom (5\/7), followed by dizziness (3\/7), movement disorder (2\/7), blurred vision (1\/7), and headache (1\/7). All exhibited ipsilateral supratentorial MRI abnormalities, exclusively on the left side and predominantly frontal. White matter lesions were observed in all patients, and cyst-like lesions were identified in four. Brain biopsy performed in two patients indicated vasculitis. All received systemic corticosteroids, either alone (2 cases) or combined with other agents (methotrexate in 5, mycophenolate mofetil in 3, IVIg in 3, tocilizumab in 2, and rituximab in 1). Over 6 months to 15 years of follow-up, neurological symptoms resolved in five patients. Skin lesions progressed in three patients, stabilized in two, and improved in two.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Linear scleroderma en coup de sabre with CNS involvement predominantly affects females and typically involves the left cerebral hemisphere. Characteristic brain MRI findings include ipsilateral supratentorial white matter abnormalities and cyst-like lesions. Combination therapy with systemic corticosteroids and methotrexate is recommended as first-line treatment, while tocilizumab may be beneficial for refractory cases.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fimmu.2026.1740848","type":"journal-article","created":{"date-parts":[[2026,2,9]],"date-time":"2026-02-09T05:26:13Z","timestamp":1770614773000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Long-term follow-up of linear scleroderma en coup de sabre in children with central nervous system involvement"],"prefix":"10.3389","volume":"17","author":[{"given":"Xingzhi","family":"Chang","sequence":"first","affiliation":[{"name":"Department of Pediatrics, Peking University First Hospital","place":["Beijing, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lihong","family":"Ren","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Chengdu Women's and Children's Central Hospital, School of Medicine, University of Electronic Science and Technology of China","place":["Chengdu, Sichuan, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ye","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Peking University First Hospital","place":["Beijing, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuehua","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Peking University First Hospital","place":["Beijing, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cuijie","family":"Wei","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Peking University First Hospital","place":["Beijing, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qingping","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Peking University First Hospital","place":["Beijing, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Meijiao","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Peking University First Hospital","place":["Beijing, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chunyan","family":"Zhao","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Peking University First Hospital","place":["Beijing, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xinhua","family":"Bao","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Peking University First Hospital","place":["Beijing, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2026,2,9]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.1111\/jdv.14458","article-title":"European Dermatology Forum S1-guideline on the diagnosis and treatment of sclerosing diseases of the skin, Part 1: localized scleroderma, systemic sclerosis and overlap syndromes","volume":"31","author":"Knobler","year":"2017","journal-title":"J Eur Acad Dermatol Venereol"},{"key":"B2","doi-asserted-by":"publisher","DOI":"10.1002\/art.22551","article-title":"The Pediatric Rheumatology European Society\/American College of Rheumatology\/European League against Rheumatism provisional classification criteria for juvenile systemic sclerosis","volume":"57","author":"Zulian","year":"2007","journal-title":"Arthritis Rheum"},{"key":"B3","doi-asserted-by":"publisher","DOI":"10.1002\/acr.20070","article-title":"Incidence of childhood linear scleroderma and systemic sclerosis in the UK and Ireland","volume":"62","author":"Herrick","year":"2010","journal-title":"Arthritis Care Res (Hoboken)"},{"key":"B4","doi-asserted-by":"publisher","DOI":"10.1097\/MOP.0000000000000785","article-title":"Diagnosis and management of linear scleroderma in children","volume":"31","author":"Pe\u00f1a-Romero","year":"2019","journal-title":"Curr Opin Pediatr"},{"key":"B5","doi-asserted-by":"publisher","first-page":"4517","DOI":"10.3390\/jcm10194517","article-title":"Therapeutic and Reconstructive Management Options in Scleroderma (Morphea) en Coup de Sabre in Children and Adults.
