Antiphospholipid syndrome can cause arterial thrombosis and pregnancy loss; hence, differential diagnoses should include seronegative antiphospholipid syndrome. We report a case of recurrent ischemic stroke caused by recurrent dissection in a patient with a history of pregnancy loss. A 33-year-old woman was admitted with global aphasia and right hemiparesis. During intra-arterial thrombectomy, a left middle cerebral artery dissection was detected. After 5.5 years, she was re-admitted for dysarthria, left facial palsy, subtle left hemiparesis, and right middle cerebral artery dissection. She tested negative for autoimmune diseases and vasculitis. However, underlying pathologic conditions could not be excluded because of the unique disease course. Finally, she was diagnosed with seronegative antiphospholipid syndrome. The concept of seronegative antiphospholipid syndrome has been proposed for patients with clinical features suggestive of antiphospholipid syndrome but with negative titers. However, this syndrome can only be diagnosed by exclusion. Furthermore, arterial dissection should be considered to be its main pathology. Antiphospholipid syndrome itself can be a risk factor for arterial dissection because it weakens the vessel walls. Therefore, diagnosis is important to prevent future complications in young patients with recurrent cerebral artery dissection, especially those associated with pregnancy-related morbidities.<\/jats:p>","DOI":"10.3390\/tomography8020062","type":"journal-article","created":{"date-parts":[[2022,3,10]],"date-time":"2022-03-10T20:19:10Z","timestamp":1646943550000},"page":"754-759","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Recurrent Cerebral Artery Dissection Associated with Seronegative Antiphospholipid Antibody Syndrome"],"prefix":"10.3390","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4633-1353","authenticated-orcid":false,"given":"Hee Sue","family":"Kim","sequence":"first","affiliation":[{"name":"Jeonbuk National University Medical School, Jeonju 54907, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eun Su","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Neurology, Jeonbuk National University Medical School and Hospital, Jeonju 54907, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Byoung-Soo","family":"Shin","sequence":"additional","affiliation":[{"name":"Department of Neurology, Jeonbuk National University Medical School and Hospital, Jeonju 54907, Korea"},{"name":"Biomedical Research Institute, Jeonbuk National University Medical School and Hospital, Jeonju 54907, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5443-3635","authenticated-orcid":false,"given":"Hyun Goo","family":"Kang","sequence":"additional","affiliation":[{"name":"Department of Neurology, Jeonbuk National University Medical School and Hospital, Jeonju 54907, Korea"},{"name":"Biomedical Research Institute, Jeonbuk National University Medical School and Hospital, Jeonju 54907, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,10]]},"reference":[{"key":"ref_1","first-page":"157","article-title":"Strokes in young adults: Epidemiology and prevention","volume":"11","year":"2015","journal-title":"Vasc.
