However, rupture can lead to catastrophic hemothorax. The vessel\u2019s deep location and non-specific symptoms make early identification a difficult task. We report a case of a 22-year-old woman who was undergoing antitubercular therapy and presented with the onset of acute dyspnea after a five-month history of wheezing and hemoptysis. Computed tomography angiography revealed a pseudoaneurysm originating from the left IPA and a massive left hemothorax. This pseudoaneurysm sac and the descending branch of the IPA were successfully embolized with a glue: lipiodol mixture, followed by hemothorax evacuation. The patient is asymptomatic at 2-month follow-up. Endovascular embolization minimizes morbidity and enables rapid recovery when anatomy is favorable. This report emphasizes the importance of cross-sectional imaging in the early diagnosis and treatment planning of atypical hemothorax presentations.<\/jats:p>","DOI":"10.1590\/1677-5449.202501272","type":"journal-article","created":{"date-parts":[[2026,1,9]],"date-time":"2026-01-09T15:02:54Z","timestamp":1767970974000},"source":"Crossref","is-referenced-by-count":1,"title":["Spontaneous massive hemothorax due to inferior phrenic artery pseudoaneurysm: endovascular treatment approach"],"prefix":"10.1590","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4899-2953","authenticated-orcid":false,"given":"Resham","family":"Singh","sequence":"first","affiliation":[{"name":"Vardhman Mahavir Medical College & Safdarjung Hospital,  India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Annoushka","family":"Daniel","sequence":"additional","affiliation":[{"name":"Vardhman Mahavir Medical College & Safdarjung Hospital,  India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naveen","family":"Kumar","sequence":"additional","affiliation":[{"name":"Vardhman Mahavir Medical College & Safdarjung Hospital,  India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","published-online":{"date-parts":[[2025]]},"reference":[{"issue":"1","key":"ref1","doi-asserted-by":"crossref","first-page":"88","DOI":"10.4103\/lungindia.lungindia_46_20","article-title":"Endovascular management of spontaneous inferior phrenic artery pseudoaneurysm presenting as massive hemothorax","volume":"38","author":"Agarwal V","year":"2021","journal-title":"Lung India"},{"issue":"1","key":"ref2","doi-asserted-by":"crossref","first-page":"187","DOI":"10.1186\/s40792-019-0739-x","article-title":"Right inferior phrenic artery pseudoaneurysm after a laparoscopic gastrectomy: a case report","volume":"5","author":"Funakoshi K","year":"2019","journal-title":"Surg Case Rep"},{"key":"ref3","doi-asserted-by":"crossref","DOI":"10.1136\/bcr-2013-201049","article-title":"Inferior phrenic artery pseudoaneurysm complicating drug-induced acute pancreatitis","volume":"2014","author":"Salem JF","year":"2014","journal-title":"BMJ Case Rep"},{"issue":"6","key":"ref4","doi-asserted-by":"crossref","first-page":"860.e9","DOI":"10.1016\/j.avsg.2011.12.017","article-title":"Pseudoaneurysm of the inferior phrenic artery presenting as an upper gastrointestinal bleed by directly rupturing into the stomach in a patient with chronic pancreatitis","volume":"26","author":"Arora A","year":"2012","journal-title":"Ann Vasc Surg"},{"issue":"6","key":"ref5","doi-asserted-by":"crossref","first-page":"2351","DOI":"10.1016\/j.radcr.2024.02.093","article-title":"Successful treatment of gastric bleeding caused by left phrenic artery pseudoaneurysm post-surgery with endovascular embolization: a case report","volume":"19","author":"Basahai I","year":"2024","journal-title":"Radiol Case Rep"}],"container-title":["Jornal Vascular Brasileiro"],"original-title":["Hemot\u00f3rax maci\u00e7o espont\u00e2neo devido a pseudoaneurisma da art\u00e9ria fr\u00eanica inferior: abordagem de tratamento endovascular"],"link":[{"URL":"http:\/\/www.scielo.br\/scielo.php?script=sci_pdf&pid=S1677-54492025000100621&tlng=en","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,1,9]],"date-time":"2026-01-09T15:02:55Z","timestamp":1767970975000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.scielo.br\/scielo.php?script=sci_arttext&pid=S1677-54492025000100621&tlng=en"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025]]},"references-count":5,"alternative-id":["S1677-54492025000100621"],"URL":"https:\/\/doi.org\/10.1590\/1677-5449.202501272","relation":{},"ISSN":["1677-7301","1677-5449"],"issn-type":[{"value":"1677-7301","type":"electronic"},{"value":"1677-5449","type":"print"}],"subject":[],"published":{"date-parts":[[2025]]},"article-number":"e20250127"}}
