He had no lower urinary tract symptoms or altered bowel habits. On examination, there was a non-tender pelvic mass which extended from the pubic symphysis to the level of the umbilicus. CT scan of the abdomen demonstrated a 22\u00d711\u00d711\u2009cm cystic mass arising from the pelvis extending into the midline and superiorly to the umbilicus. Other than raised carcinoembryonic antigen of 7.6\u2009ng\/mL (&lt;5.0), the remainder of his blood test were unremarkable. Flexible cystoscopy demonstrated a convex deformity of the bladder wall in keeping with the compression and displacement as seen on the CT. The patient underwent an open excision of the cystic structure (urachal remnant), partial cystectomy, partial excision of anterior abdominal wall and pelvic lymphadenectomy. A check cystogram performed 12 days following the initial operation was unremarkable.<\/jats:p>","DOI":"10.1136\/bcr-2018-228089","type":"journal-article","created":{"date-parts":[[2019,1,23]],"date-time":"2019-01-23T06:35:35Z","timestamp":1548225335000},"page":"e228089","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Urachal Mucinous Cystadenocarcinoma"],"prefix":"10.1136","volume":"12","author":[{"given":"Ryan","family":"Pereira","sequence":"first","affiliation":[{"name":"Urology, Princess Alexandra Hospital, Woolloongabba, Queensland, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0778-0375","authenticated-orcid":false,"given":"Stephen","family":"McGeorge","sequence":"additional","affiliation":[{"name":"Urology, Toowoomba Hospital, Queensland, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marlon","family":"Perera","sequence":"additional","affiliation":[{"name":"Urology, Princess Alexandra Hospital, Woolloongabba, Queensland, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ian","family":"Vela","sequence":"additional","affiliation":[{"name":"Urology, Princess Alexandra Hospital, Woolloongabba, Queensland, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2019,1,22]]},"reference":[{"key":"2025082709043506000_12.1.e228089.1","doi-asserted-by":"publisher","DOI":"10.1148\/radiographics.21.2.g01mr02451"},{"key":"2025082709043506000_12.1.e228089.2","doi-asserted-by":"crossref","first-page":"1808","DOI":"10.1016\/j.humpath.2015.07.021","article-title":"Urachal carcinoma: a pathologic and clinical study of 46 cases","volume":"46","author":"Dhillon","year":"2015","journal-title":"Hum Pathol"},{"key":"2025082709043506000_12.1.e228089.3","doi-asserted-by":"publisher","DOI":"10.1097\/01.ju.0000054646.49381.01"},{"key":"2025082709043506000_12.1.e228089.4","doi-asserted-by":"publisher","DOI":"10.1016\/0090-4295(85)90112-8"},{"key":"2025082709043506000_12.1.e228089.5","doi-asserted-by":"crossref","first-page":"170","DOI":"10.1186\/1477-7819-11-170","article-title":"Surgical and chemotherapeutic experience regarding a urachal carcinoma with repeated relapse: case report and literature review","volume":"11","author":"Zong","year":"2013","journal-title":"World J Surg Oncol"},{"key":"2025082709043506000_12.1.e228089.6","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(09)60491-8"},{"key":"2025082709043506000_12.1.e228089.7","unstructured":"National Comprehensive Cancer Network.
