It can exhibit various atypical presentations. However, cases of FMF concurrently presenting with chronic thrombosis and myositis have not been previously reported. A 41-year-old male presented with alternating severe bilateral leg pain, stiffness, and localised swellings without fever or abdominal symptoms. His history included inflammatory joint pain treated with prednisolone. Physical examination revealed leg pain, limited ankle joint movement, and tender swellings in thighs, forearms, and feet. Collateral abdominal veins were also observed. Unresponsive to prednisolone and colchicine, the patient underwent MRI, revealing muscle inflammation in both legs and thighs and chronic thrombosis in the infrarenal inferior vena cava. Genetic testing confirmed the heterozygotic M694V mutation, diagnosing an atypical FMF. This case uniquely showcases coexisting myositis and chronic thrombosis in FMF. Myalgia is common in FMF, with M694V mutation associated with severe muscular symptoms. The lack of fever and myositis findings differentiate our case from protracted febrile myalgia syndrome. FMF\u2019s chronic inflammatory state is known to influence thrombosis risk, and our findings align with this association. Chronic thromboembolism and myositis together signify an unusual clinical presentation of FMF. This case highlights the potential for FMF to present with complex manifestations beyond the conventional symptoms. Myositis and vascular involvement should prompt consideration of FMF diagnosis when combined with patient history, clinical features, and laboratory results. These rare associations underscore the need for further research to enhance understanding of FMF\u2019s diverse clinical spectrum.<\/jats:p>","DOI":"10.1093\/mrcr\/rxad072","type":"journal-article","created":{"date-parts":[[2023,12,19]],"date-time":"2023-12-19T15:09:09Z","timestamp":1702998549000},"page":"383-385","source":"Crossref","is-referenced-by-count":0,"title":["Unprecedented coexistence of autoinflammatory myositis and chronic thrombosis with heterozygotic M694V mutation: An atypical presentation of familial Mediterranean fever"],"prefix":"10.1093","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4672-5977","authenticated-orcid":false,"given":"Furkan","family":"Bahar","sequence":"first","affiliation":[{"name":"Division of Rheumatology, Department of Internal Medicine, Cerrahpasa Medical Faculty, Istanbul University-Cerrahpasa , Istanbul, Turkey"},{"name":"Department of Medical Oncology, Dana Farber Cancer Institute, Harvard University , Boston, MA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9561-2282","authenticated-orcid":false,"given":"Serdal","family":"Ugurlu","sequence":"additional","affiliation":[{"name":"Division of Rheumatology, Department of Internal Medicine, Cerrahpasa Medical Faculty, Istanbul University-Cerrahpasa , Istanbul, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2023,12,20]]},"reference":[{"key":"2024070814404597800_R1","doi-asserted-by":"crossref","first-page":"1591","DOI":"10.3906\/sag-2008-11","article-title":"Familial Mediterranean fever, from pathogenesis to treatment: a contemporary review","volume":"50","author":"Tufan","year":"2020","journal-title":"Turk J Med Sci"},{"key":"2024070814404597800_R2","doi-asserted-by":"crossref","first-page":"1503","DOI":"10.1007\/s10067-015-2916-z","article-title":"Non-canonical manifestations of familial Mediterranean fever: a changing paradigm","volume":"34","author":"Rigante","year":"2015","journal-title":"Clin Rheumatol"},{"key":"2024070814404597800_R3","doi-asserted-by":"crossref","first-page":"227","DOI":"10.1016\/0002-9343(67)90167-2","article-title":"Familial Mediterranean fever.
