The patient was admitted in the emergency department because of diffuse abdominal bloating and discomfort. Ultrasonography (US) showed a heterogeneous abdominopelvic mass. Magnetic resonance imaging (MRI) was performed to further characterise and revealed a myometrial pedunculated tumour. Despite its marked T2-signal heterogeneity and volume, there were no other suspicious findings to suggest a malignant nature; therefore, fertility-sparing myomectomy was performed. Leiomyomas frequently undergo degenerative changes altering their imaging appearances. Leiomyomas with uncommon degenerative changes may be difficult to differentiate from malignant myometrial tumours, based solely on imaging. To the best of our knowledge, a diffuse hydropic degeneration imaging appearance has only been described twice in the literature. We describe the imaging appearance of this rare form of leiomyoma drawing attention to its differential diagnosis.<\/jats:p>","DOI":"10.1136\/bcr-2015-211929","type":"journal-article","created":{"date-parts":[[2015,9,8]],"date-time":"2015-09-08T07:39:17Z","timestamp":1441697957000},"page":"bcr2015211929","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":12,"title":["Hydropic leiomyoma of the uterus presenting as a giant abdominal mass"],"prefix":"10.1136","volume":"2015","author":[{"given":"Mariana","family":"Horta","sequence":"first","affiliation":[{"name":"Department of Radiology, Centro Hospitalar Lisboa Ocidental, Lisbon, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Teresa Margarida","family":"Cunha","sequence":"additional","affiliation":[{"name":"Department of Radiology, Instituto Portugu\u00eas de Oncologia de Lisboa Francisco Gentil, Lisbon, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rita","family":"Oliveira","sequence":"additional","affiliation":[{"name":"Department of Pathology, Centro Hospitalar Lisboa Ocidental, Lisbon, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paula","family":"Magro","sequence":"additional","affiliation":[{"name":"Department of Surgery, Centro Hospitalar Lisboa Ocidental, Lisbon, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2015,9,8]]},"reference":[{"key":"2025082700305141000_2015.sep07_2.bcr2015211929.1","first-page":"135","article-title":"Classification of tumours of the ovary","volume-title":"WHO classification of tumours","volume":"6","author":"Kurman","year":"2014"},{"key":"2025082700305141000_2015.sep07_2.bcr2015211929.2","doi-asserted-by":"publisher","DOI":"10.1016\/j.crad.2011.12.008"},{"key":"2025082700305141000_2015.sep07_2.bcr2015211929.3","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejrnm.2015.03.003"},{"key":"2025082700305141000_2015.sep07_2.bcr2015211929.4","doi-asserted-by":"publisher","DOI":"10.1148\/radiographics.19.5.g99se131179"},{"key":"2025082700305141000_2015.sep07_2.bcr2015211929.5","doi-asserted-by":"crossref","first-page":"595","DOI":"10.5858\/2008-132-595-SMTOTU","article-title":"Smooth muscle tumors of the uterus: a practical approach","volume":"132","author":"Toledo","year":"2008","journal-title":"Arch Pathol Lab Med"},{"key":"2025082700305141000_2015.sep07_2.bcr2015211929.6","doi-asserted-by":"publisher","DOI":"10.1259\/bjr\/50866065"},{"key":"2025082700305141000_2015.sep07_2.bcr2015211929.7","doi-asserted-by":"publisher","DOI":"10.1007\/s00330-013-2819-9"},{"key":"2025082700305141000_2015.sep07_2.bcr2015211929.8","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.181.5.1811369"},{"key":"2025082700305141000_2015.sep07_2.bcr2015211929.9","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejrad.2009.03.005"},{"key":"2025082700305141000_2015.sep07_2.bcr2015211929.10","doi-asserted-by":"publisher","DOI":"10.1007\/s00330-007-0787-7"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2015-211929","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T07:30:56Z","timestamp":1756279856000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2015-211929"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,9,8]]},"references-count":10,"alternative-id":["10.1136\/bcr-2015-211929"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2015-211929","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015,9,8]]}}}
