These tumors most often arise in the retroperitoneal region (52%) and posterior mediastinum (39%), while extra-adrenal lesions account for 51% of abdominal GN cases. This paper presents a 66-year-old female with paroxysmal atrial fibrillation found to have a left retroperitoneal mass on imaging. A 9.5-cm tumor was fully resected using robot-assisted laparoscopy. Pathology confirmed GN with ectopic inferior vena cava (IVC) invasion. This case highlights the need to consider retroperitoneal GN in the differential diagnosis of vascular structures. In addition, three-dimensional reconstruction is valuable for surgical planning, and robot-assisted surgery is preferred for complex cases.<\/jats:p>","DOI":"10.3389\/fsurg.2026.1730386","type":"journal-article","created":{"date-parts":[[2026,4,8]],"date-time":"2026-04-08T05:33:22Z","timestamp":1775626402000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Retroperitoneal ganglioneuroma with ectopic inferior vena cava invasion: a case report"],"prefix":"10.3389","volume":"13","author":[{"given":"Baisheng","family":"Xu","sequence":"first","affiliation":[{"name":"Department of Urology, The First People's Hospital of Xiushui County","place":["Jiujiang, Jiangxi, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Huanglin","family":"Duan","sequence":"additional","affiliation":[{"name":"Department of Urology, The First People's Hospital of Xiushui County","place":["Jiujiang, Jiangxi, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hongbing","family":"Gao","sequence":"additional","affiliation":[{"name":"Department of Urology, The First People's Hospital of Xiushui County","place":["Jiujiang, Jiangxi, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fengui","family":"Leng","sequence":"additional","affiliation":[{"name":"Department of Urology, The First People's Hospital of Xiushui County","place":["Jiujiang, Jiangxi, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Feng","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Urology, The First People's Hospital of Xiushui County","place":["Jiujiang, Jiangxi, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hui","family":"Che","sequence":"additional","affiliation":[{"name":"Department of Urology, The First People's Hospital of Xiushui County","place":["Jiujiang, Jiangxi, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liangfei","family":"Guo","sequence":"additional","affiliation":[{"name":"Department of Urology, The First People's Hospital of Xiushui County","place":["Jiujiang, Jiangxi, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jianmiao","family":"Hu","sequence":"additional","affiliation":[{"name":"Department of Urology, The First People's Hospital of Xiushui County","place":["Jiujiang, Jiangxi, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xu","family":"Leng","sequence":"additional","affiliation":[{"name":"Department of Urology, The First People's Hospital of Xiushui County","place":["Jiujiang, Jiangxi, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Junwei","family":"Gu","sequence":"additional","affiliation":[{"name":"Department of Urology, The First People's Hospital of Xiushui County","place":["Jiujiang, Jiangxi, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenqiang","family":"Dong","sequence":"additional","affiliation":[{"name":"Department of Urology, The First People's Hospital of Xiushui County","place":["Jiujiang, Jiangxi, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2026,4,8]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"2617","DOI":"10.12998\/wjcc.v7.i17.2617","article-title":"Cause of postprandial vomiting\u2014a giant retroperitoneal ganglioneuroma enclosing large blood vessels: a case report","volume":"7","author":"Zheng","year":"2019","journal-title":"World J Clin Cases"},{"key":"B2","doi-asserted-by":"publisher","first-page":"4863","DOI":"10.3892\/ol.2017.6797","article-title":"Ex vivo excision of retroperitoneal soft tissue tumors: a case report","volume":"14","author":"Rahnemai-Azar","year":"2017","journal-title":"Oncol Lett"},{"key":"B3","doi-asserted-by":"publisher","first-page":"1065","DOI":"10.1097\/SMJ.0b013e3181b2fd37","article-title":"Retroperitoneal ganglioneuroma in an adult patient: a case report and literature review of the last decade","volume":"102","author":"Papavramidis","year":"2009","journal-title":"South Med J"},{"key":"B4","doi-asserted-by":"publisher","first-page":"1589","DOI":"10.2106\/00004623-199911000-00011","article-title":"Symptomatic ganglioneuroma of bone.
