Patients are often asymptomatic or present with nonspecific abdominal pain, which can hinder and delay diagnosis. We report the case of an 80\u2013year\u2013old male patient with a 3-month history of nonspecific abdominal pain. The diagnosis was established only intraoperatively, when the smooth muscle neoplasm initially suspected to originate from the duodenum was identified as an IVC-LMS. The patient underwent partial resection of the IVC with prosthetic interposition, followed by adjuvant chemoradiotherapy. Complete surgical resection remains the gold standard treatment of IVC-LMS and the only approach with curative potential. Prognosis largely depends on the stage at diagnosis.<\/jats:p>","DOI":"10.1590\/1677-5449.202501152","type":"journal-article","created":{"date-parts":[[2026,3,23]],"date-time":"2026-03-23T11:04:56Z","timestamp":1774263896000},"source":"Crossref","is-referenced-by-count":0,"title":["Leiomyosarcoma of the inferior vena cava: a case report of a challenging diagnosis of abdominal pain"],"prefix":"10.1590","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9250-1360","authenticated-orcid":false,"given":"Am\u00e9lia","family":"Gaspar","sequence":"first","affiliation":[{"name":"USF Mondego,  Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6360-7561","authenticated-orcid":false,"given":"Matilde Vala","family":"Esteves","sequence":"additional","affiliation":[{"name":"USF Mondego,  Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2271-1762","authenticated-orcid":false,"given":"Filipe Santos","family":"Leal","sequence":"additional","affiliation":[{"name":"USF Mondego,  Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6434-1937","authenticated-orcid":false,"given":"Clarisse Cal\u00e7a","family":"Coelho","sequence":"additional","affiliation":[{"name":"USF Mondego,  Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3816-7231","authenticated-orcid":false,"given":"Cristina Costa","family":"Silva","sequence":"additional","affiliation":[{"name":"USF Mondego,  Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-4021-9766","authenticated-orcid":false,"given":"Jo\u00e3o","family":"Arcanjo","sequence":"additional","affiliation":[{"name":"USF Mondego,  Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","published-online":{"date-parts":[[2026]]},"reference":[{"issue":"6","key":"ref1","article-title":"Approach to different types of inferior vena cava leiomyosarcomas: a vascular surgeon\u2019s perspective","volume":"15","author":"Chellasamy RT","year":"2023","journal-title":"Cureus"},{"issue":"1","key":"ref2","doi-asserted-by":"crossref","first-page":"227","DOI":"10.47162\/RJME.61.1.25","article-title":"Leiomyosarcoma of the inferior vena cava.
