Pregnancy is known to be associated with an increased risk of tumour rupture causing hypovolaemic shock, which is usually managed surgically or through an embolisation procedure. However, having surgery during pregnancy predisposes the mother to a preterm delivery, and the unknown influences of radiation exposure to the fetus make the management of such cases very challenging. A 30-year-old pregnant woman had a sudden onset of gross haematuria at the 20th week of her pregnancy. The MRI showed a 10\u2005cm mass suggestive of AML in the left kidney, with evidence of an intrarenal haematoma. To avoid an iatrogenic preterm delivery and unnecessary fetal exposure to radiation, conservative management was conducted until 34\u2005weeks of gestation, when she came to our hospital reporting of flank pain. An endovascular treatment was performed immediately after an emergency caesarean delivery.<\/jats:p>","DOI":"10.1136\/bcr-2016-217284","type":"journal-article","created":{"date-parts":[[2017,1,6]],"date-time":"2017-01-06T17:38:24Z","timestamp":1483724304000},"page":"bcr2016217284","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":9,"title":["Spontaneous rupture of renal angiomyolipoma during pregnancy"],"prefix":"10.1136","volume":"2017","author":[{"given":"Li","family":"Ao","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eriko","family":"Ogasahara","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yasuhiko","family":"Okuda","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuji","family":"Hirata","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2017,1,6]]},"reference":[{"key":"2025042702193388000_2017.jan06_1.bcr2016217284.1","doi-asserted-by":"publisher","DOI":"10.1007\/s00261-014-0129-6"},{"key":"2025042702193388000_2017.jan06_1.bcr2016217284.2","doi-asserted-by":"publisher","DOI":"10.1136\/jmg.33.6.480"},{"key":"2025042702193388000_2017.jan06_1.bcr2016217284.3","doi-asserted-by":"crossref","first-page":"89","DOI":"10.1016\/j.ijscr.2015.01.004","article-title":"Surgical management of haemorrhaging renal angiomyolipoma in pregnancy","volume":"7c","author":"Preece","year":"2015","journal-title":"Int J Surg Case Rep"},{"key":"2025042702193388000_2017.jan06_1.bcr2016217284.4","doi-asserted-by":"crossref","first-page":"710","DOI":"10.1111\/iju.12775","article-title":"Spontaneous rupture of a renal angiomyolipoma at 25 weeks of pregnancy treated with transarterial embolization: a case report and review of the literature","volume":"22","author":"Myoen","year":"2015","journal-title":"Int J Urol"},{"key":"2025042702193388000_2017.jan06_1.bcr2016217284.5","doi-asserted-by":"crossref","first-page":"377","DOI":"10.1590\/SO100-720320140005019","article-title":"Spontaneous rupture of renal angiomyolipoma during pregnancy","volume":"36","author":"dos Santos","year":"2014","journal-title":"Rev Bras Ginecol Obstet"},{"key":"2025042702193388000_2017.jan06_1.bcr2016217284.6","doi-asserted-by":"crossref","first-page":"628","DOI":"10.3109\/01443615.2013.810201","article-title":"Rupture of renal angiomyolipoma in pregnancy","volume":"33","author":"Pontis","year":"2013","journal-title":"J Obstet Gynaecol"},{"key":"2025042702193388000_2017.jan06_1.bcr2016217284.7","doi-asserted-by":"crossref","first-page":"1193","DOI":"10.1007\/s00404-013-2902-0","article-title":"Severe retroperitoneal haemorrhage in the first trimester of a multiple pregnancy after spontaneous rupture of renal angiomyolipoma","volume":"288","author":"Ferianec","year":"2013","journal-title":"Arch Gynecol Obstet"},{"key":"2025042702193388000_2017.jan06_1.bcr2016217284.8","doi-asserted-by":"publisher","DOI":"10.1177\/014107689909200813"},{"key":"2025042702193388000_2017.jan06_1.bcr2016217284.9","doi-asserted-by":"publisher","DOI":"10.1097\/01.ju.0000177497.31986.64"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2016-217284","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,27]],"date-time":"2025-04-27T09:19:45Z","timestamp":1745745585000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2016-217284"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,1,6]]},"references-count":9,"alternative-id":["10.1136\/bcr-2016-217284"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2016-217284","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017,1,6]]}}}
