We report a case initially presenting with recurrent nausea and vomiting in a 52\u2010year\u2010old woman. Laboratory studies revealed elevated serum \u03b2\u2010hCG levels, and ultrasonography demonstrated a pelvic mass extending from the parametrial area into the IVC. Pathological examination of a pelvic mass biopsy confirmed the diagnosis of choriocarcinoma. Further assessment identified pulmonary hypertension and emboli within small pulmonary artery branches. The patient received EMA\u2010CO chemotherapy and achieved complete remission, with no evidence of recurrence during a one\u2010year follow\u2010up. This case highlights the diagnostic challenges posed by non\u2010classical metastases and underscores the importance of considering choriocarcinoma in the differential diagnosis of women with a pregnancy history and unexplained systemic symptoms.<\/jats:p>","DOI":"10.1111\/jog.70510","type":"journal-article","created":{"date-parts":[[2026,10,3]],"date-time":"2026-10-03T06:07:02Z","timestamp":1791007622000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Gestational Choriocarcinoma With Inferior Vena Cava Tumor Thrombus Formation"],"prefix":"10.1111","volume":"52","author":[{"given":"Qiong","family":"Yang","sequence":"first","affiliation":[{"name":"Department of Gynecology and Obstetrics Xinqiao Hospital of Army Medical University  Chongqing People's Republic of China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-9196-2273","authenticated-orcid":false,"given":"Ziyan","family":"Liang","sequence":"additional","affiliation":[{"name":"Department of Gynecology and Obstetrics Xinqiao Hospital of Army Medical University  Chongqing People's Republic of China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhenhua","family":"Ming","sequence":"additional","affiliation":[{"name":"Department of Gynecology and Obstetrics Xinqiao Hospital of Army Medical University  Chongqing People's Republic of China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bing","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Radiology Xinqiao Hospital of Army Medical University  Chongqing People's Republic of China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rongkai","family":"Xie","sequence":"additional","affiliation":[{"name":"Department of Gynecology and Obstetrics Xinqiao Hospital of Army Medical University  Chongqing People's Republic of China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,10,2]]},"reference":[{"key":"e_1_2_13_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaccas.2025.104912"},{"key":"e_1_2_13_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/MS9.0000000000003872"},{"key":"e_1_2_13_4_1","article-title":"Intestinal Metastasis of Choriocarcinoma: A Case Report of a Rare Cause of Gastrointestinal Bleeding","volume":"17","author":"Winston K.","year":"2025","journal-title":"Cureus"},{"key":"e_1_2_13_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/ueg2.70007"},{"key":"e_1_2_13_6_1","doi-asserted-by":"publisher","DOI":"10.1186\/s13023-025-04014-6"},{"key":"e_1_2_13_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejso.2024.108727"},{"issue":"1","key":"e_1_2_13_8_1","first-page":"62","article-title":"Group 4 Pulmonary Hypertension due to Choriocarcinoma After Molar Pregnancy: Case Report and Review","volume":"96","author":"Monta\u00f1ez\u2010Aguirre \u00c1.
