This anomaly is often associated with scimitar syndrome. We present a unique case of an isolated accessory hemidiaphragm\u2014devoid of the characteristic vascular anomalies typical of scimitar syndrome\u2014discovered incidentally during thoracoscopic surgery performed for a pulmonary nodule. This report elaborates the rationale for performing a concurrent partial membranectomy and underscores the necessity of an individualized surgical strategy in such cases.<\/jats:p>","DOI":"10.3389\/fsurg.2026.1790499","type":"journal-article","created":{"date-parts":[[2026,3,26]],"date-time":"2026-03-26T12:57:58Z","timestamp":1774529878000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Discovery and management of accessory hemidiaphragm during video-assisted thoracoscopic segmentectomy for pulmonary nodule: a case report"],"prefix":"10.3389","volume":"13","author":[{"given":"Yijun","family":"Fan","sequence":"first","affiliation":[{"name":"West China School of Medicine, Sichuan University","place":["Chengdu, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tingrui","family":"Mei","sequence":"additional","affiliation":[{"name":"Department of Thoracic Surgery, West China Hospital, Sichuan University","place":["Chengdu, China"]},{"name":"Lung Cancer Center \/ Lung Cancer Institute, West China Hospital, Sichuan University","place":["Chengdu, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lei","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Thoracic Surgery, West China Hospital, Sichuan University","place":["Chengdu, China"]},{"name":"Lung Cancer Center \/ Lung Cancer Institute, West China Hospital, Sichuan University","place":["Chengdu, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaoling","family":"Gu","sequence":"additional","affiliation":[{"name":"Lung Cancer Center \/ Lung Cancer Institute, West China Hospital, Sichuan University","place":["Chengdu, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ya","family":"Gou","sequence":"additional","affiliation":[{"name":"West China Medical Technology Transfer Center","place":["Chengdu, Sichuan, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lin","family":"Jiang","sequence":"additional","affiliation":[{"name":"West China Medical Technology Transfer Center","place":["Chengdu, Sichuan, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jingsi","family":"Dong","sequence":"additional","affiliation":[{"name":"Department of Thoracic Surgery, West China Hospital, Sichuan University","place":["Chengdu, China"]},{"name":"Lung Cancer Center \/ Lung Cancer Institute, West China Hospital, Sichuan University","place":["Chengdu, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2026,3,26]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"903","DOI":"10.1378\/chest.14-2765","article-title":"The impact of visceral pleural invasion in node-negative non-small cell lung cancer a systematic review and meta-analysis","volume":"148","author":"Jiang","year":"2015","journal-title":"Chest"},{"key":"B2","doi-asserted-by":"publisher","first-page":"E317","DOI":"10.1016\/j.athoracsur.2016.03.022","article-title":"Right thoracotomy to repair scimitar syndrome and an accessory hemidiaphragm","volume":"102","author":"Al-Yamani","year":"2016","journal-title":"Ann Thorac Surg"},{"key":"B3","doi-asserted-by":"publisher","first-page":"1326","DOI":"10.1016\/j.jpedsurg.2014.03.005","article-title":"Accessory hemi diaphragm","volume":"49","author":"Radhakrishnan","year":"2014","journal-title":"J Pediatr Surg"},{"key":"B4","doi-asserted-by":"publisher","first-page":"15","DOI":"10.1007\/BF02387847","article-title":"Causes of congenital unilateral pulmonary hypoplasia -
