Presentation in adult life is less common, accounting for 20% of cases. A 19-year-old female patient presented to the Emergency Department with severe abdominal distension, a palpable abdominal mass, mild jaundice and low grade fever. Ultrasound, computed tomography (CT) and magnetic resonance imaging of the abdomen showed a massive septated cystic lesion filling the entire abdomen with a significant mass effect on surrounding structures. Origin of the lesion was unclear and diagnosis included a giant mesenteric or duplication cyst, massive gallbladder with hydrops, biliary cystadenoma and giant choledochal cyst, among others. Final diagnosis was a Type IA choledochal cyst with massive asymmetric cystic dilatation of the extra-hepatic segments of the left hepatic duct with asymmetric dilatation of the right hepatic duct. Patient had an uneventful recovery after resection of the entire extrahepatic cyst and Roux-en-Y hepaticojejunostomy at the level of the hilum. In this article, we correlate CT and MRI findings to gross and histopathological findings of this giant Todani's Type IA choledochal cyst.<\/jats:p>","DOI":"10.4103\/2156-7514.120785","type":"journal-article","created":{"date-parts":[[2013,10,29]],"date-time":"2013-10-29T12:59:59Z","timestamp":1383051599000},"page":"45","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Giant Choledochal Cyst Mimicking Massive Gallbladder Hydrops in an Adult Patient: Multi Detector Computed Tomography and Magnetic Resonance Imaging Findings Correlated to Gross and Histopathological Findings"],"prefix":"10.25259","volume":"3","author":[{"given":"Joon-Il","family":"Choi","sequence":"first","affiliation":[{"name":"Department of Radiological Sciences, University of California, Irvine, Orange, CA, The United States of America"},{"name":"Department of Radiology, Seoul St. Mary's Hospital, College of Medicine, The Catholic University of Korea, Seoul, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chandana","family":"Lall","sequence":"additional","affiliation":[{"name":"Department of Radiological Sciences, University of California, Irvine, Orange, CA, The United States of America"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Puneet","family":"Bhargava","sequence":"additional","affiliation":[{"name":"Department of Radiology, University of Washington, Seattle, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David K.","family":"Imagawa","sequence":"additional","affiliation":[{"name":"Department of Surgery, University of California, Irvine, Orange, CA, The United States of America"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"10894","published-online":{"date-parts":[[2013,10,29]]},"reference":[{"key":"10.4103\/2156-7514.120785\/ref-1","doi-asserted-by":"crossref","first-page":"263","DOI":"10.1016\/0002-9610(77)90359-2","article-title":"Congenital bile duct cysts: Classification, operative procedures, and review of thirty-seven cases including cancer arising from choledochal cyst","volume":"134","author":"Todani","year":"1977","journal-title":"Am J Surg"},{"key":"10.4103\/2156-7514.120785\/ref-2","first-page":"69","article-title":"Nationwide survey of cases of choledochal cyst.
