We report a 29\u2010year\u2010old man with no history of chest trauma who presented with left\u2010sided chest pain for 3\u2009months. Initial routine contrast\u2010enhanced chest computed tomography (CT) revealed a pleural mass\u2010like lesion. Ultrasound\u2010guided biopsy was initially considered. However, pre\u2010biopsy chest ultrasound revealed pulsatile vascular flow within the lesion, raising suspicion for a vascular malformation. Subsequent CT angiography (CTA) demonstrated tortuous vessels supplied by multiple intercostal arteries with venous drainage into the intercostal veins and azygos system, confirming a congenital posterior intercostal AVM. Given persistent symptoms and surgical complexity, transarterial embolization with Onyx and N\u2010butyl cyanoacrylate (NBCA) resulted in marked shunt reduction and symptomatic improvement. This case reminds clinicians to consider intercostal AVMs in the differential diagnosis of pleural\u2010based lesions and reports our experience with endovascular embolization.<\/jats:p>","DOI":"10.1002\/rcr2.70603","type":"journal-article","created":{"date-parts":[[2026,5,11]],"date-time":"2026-05-11T07:54:16Z","timestamp":1778486056000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Posterior Intercostal Arteriovenous Malformation Mimicking a Pleural Mass: A Diagnostic Pitfall"],"prefix":"10.1002","volume":"14","author":[{"given":"Yun\u2010Yu","family":"Chung","sequence":"first","affiliation":[{"name":"Department of Chest Medicine Taichung Veterans General Hospital  Taichung Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shao\u2010Yen","family":"Liang","sequence":"additional","affiliation":[{"name":"Department of Medical Imaging Taichung Veterans General Hospital  Taichung Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pi\u2010Yi","family":"Chang","sequence":"additional","affiliation":[{"name":"Department of Medical Imaging Taichung Veterans General Hospital  Taichung Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-3554-6111","authenticated-orcid":false,"given":"Wei\u2010Fan","family":"Ou","sequence":"additional","affiliation":[{"name":"Department of Chest Medicine Taichung Veterans General Hospital  Taichung Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,5,11]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.2214\/AJR.05.0367"},{"issue":"7","key":"e_1_2_10_3_1","article-title":"High\u2010Flow Congenital Arteriovenous Malformation of the Posterior Chest Wall in a Young Adult: A Case Report on a Rare Anomaly","volume":"17","author":"Dhamala I.","year":"2025","journal-title":"Cureus"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.athoracsur.2012.10.074"},{"issue":"7","key":"e_1_2_10_5_1","first-page":"798","article-title":"A Case Report of Arteriovenous Malformation on the Chest Wall","volume":"29","author":"Park S.
