However, not all cases are malignant. Non-malignant diseases, such as Meigs syndrome and pseudo-Meigs syndrome, must be part of your differential. We present a 56-year-old woman with dyspnoea secondary to a right pleural effusion. After further investigations, a serum cancer antigen-125 was found to be elevated at 437.3\u2009U\/mL. CT of her abdomen and pelvis showed a large heterogeneous mass in the pelvis measuring 13.2\u00d79.7\u00d715.1\u2009cm with mild ascites. She was initially thought to have ovarian carcinoma and underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy with omental biopsy. Pathology from the surgical specimen revealed a hydropic leiomyoma and after removal of pelvic mass her pleural effusion and ascites completely resolved. She was ultimately diagnosed with the rare pseudo-Meigs syndrome.<\/jats:p>","DOI":"10.1136\/bcr-2018-226454","type":"journal-article","created":{"date-parts":[[2019,1,11]],"date-time":"2019-01-11T04:30:11Z","timestamp":1547181011000},"page":"bcr-2018-226454","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":15,"title":["Hydropic leiomyoma presenting as a rare condition of pseudo-Meigs syndrome: literature review and a case of a pseudo-Meigs syndrome mimicking ovarian carcinoma with elevated CA125"],"prefix":"10.1136","volume":"12","author":[{"given":"Mehrnoosh","family":"Pauls","sequence":"first","affiliation":[{"name":"Department of Medicine, Dalhousie University, Halifax, Nova Scotia, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Heather","family":"MacKenzie","sequence":"additional","affiliation":[{"name":"Department of Medicine, Dalhousie University, Halifax, Nova Scotia, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5482-4705","authenticated-orcid":false,"given":"Ravi","family":"Ramjeesingh","sequence":"additional","affiliation":[{"name":"Medicine, QE2 Health Science Center, Halifax, Nova Scotia, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2019,1,10]]},"reference":[{"key":"2025082802421915000_12.1.bcr-2018-226454.1","doi-asserted-by":"crossref","first-page":"29","DOI":"10.1002\/j.2205-0140.2012.tb00140.x","article-title":"and Pseudo-meigs\u2019 syndrome","volume":"15","author":"Saha","year":"2012","journal-title":"Australas J Ultrasound Med"},{"key":"2025082802421915000_12.1.bcr-2018-226454.2","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-6757(98)90141-3"},{"key":"2025082802421915000_12.1.bcr-2018-226454.3","first-page":"471","article-title":"Pelvic tumors other than fibromas of the ovary with ascites and hydrothorax","volume":"3","author":"Meigs","year":"1954","journal-title":"Obstet Gynecol"},{"key":"2025082802421915000_12.1.bcr-2018-226454.4","doi-asserted-by":"publisher","DOI":"10.1001\/archinte.158.12.1378"},{"key":"2025082802421915000_12.1.bcr-2018-226454.5","doi-asserted-by":"publisher","DOI":"10.1016\/S0936-6555(98)80071-X"},{"key":"2025082802421915000_12.1.bcr-2018-226454.6","doi-asserted-by":"publisher","DOI":"10.1016\/S0029-7844(98)00130-6"},{"key":"2025082802421915000_12.1.bcr-2018-226454.7","doi-asserted-by":"crossref","first-page":"283","DOI":"10.1111\/j.1447-0756.2000.tb01323.x","article-title":"Uterine leiomyoma causing massive ascites and left pleural effusion with elevated CA 125: a case report","volume":"26","author":"Migishima","year":"2000","journal-title":"J Obstet Gynaecol Res"},{"key":"2025082802421915000_12.1.bcr-2018-226454.8","doi-asserted-by":"publisher","DOI":"10.1006\/gyno.2001.6251"},{"key":"2025082802421915000_12.1.bcr-2018-226454.9","first-page":"443","article-title":"Pseudo-meigs syndrome: uterine leiomyoma with bladder attachment associated with ascites and hydrothorax - a rare case of a rare syndrome","volume":"25","author":"Weise","year":"2002","journal-title":"Onkologie"},{"key":"2025082802421915000_12.1.bcr-2018-226454.10","doi-asserted-by":"crossref","first-page":"127","DOI":"10.1007\/s00330-002-1464-5","article-title":"Pedunculated uterine leiomyoma associated with pseudo-Meigs\u2019 syndrome and elevated CA-125 level: CT features","volume":"12 Suppl 3","author":"Kebapci","year":"2002","journal-title":"Eur Radiol"},{"key":"2025082802421915000_12.1.bcr-2018-226454.11","doi-asserted-by":"crossref","first-page":"933","DOI":"10.5858\/2004-128-933-PQCAYW","article-title":"Pathologic quiz case: a 40-year-old woman with a large pelvic mass, ascites, massive right hydrothorax, and elevated CA 125.
