We describe a patient with gross dilatation of the main pancreatic duct without evidence of causative underlying pathology suggesting congenital dilatation of the pancreatic duct. A 36-year-old man presented with signs of intestinal obstruction and a history of surgery for congenital pyloric stenosis. Incidental findings on CT showed a massively dilated main pancreatic duct. On MRI there was no duct irregularity or solid mural nodule, making a main duct intraductal papillary mucinous neoplasm unlikely. Endoscopic ultrasound findings were in keeping with those on MRI. Fine needle aspiration revealed a non-viscous fluid with a low carcinoembryonic antigen and high amylase concentration, consistent with normal pancreatic fluid levels rather than a mucinous collection. After 1\u2009year, the cyst remains unchanged. This patient will be kept under surveillance with yearly MRI.<\/jats:p>","DOI":"10.1136\/bcr-2017-221191","type":"journal-article","created":{"date-parts":[[2017,9,29]],"date-time":"2017-09-29T00:45:24Z","timestamp":1506645924000},"page":"bcr-2017-221191","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Possible congenital dilatation of the pancreatic duct"],"prefix":"10.1136","volume":"2017","author":[{"given":"Abhijeet","family":"Tavare","sequence":"first","affiliation":[{"name":"Medical Sciences Division, University of Oxford, Oxford, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alex N","family":"Gordon-Weeks","sequence":"additional","affiliation":[{"name":"Nuffield Department of Surgical Sciences, University of Oxford, Oxford, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Helen","family":"Bungay","sequence":"additional","affiliation":[{"name":"Department of Radiology, Oxford University Hospitals Trust, Oxford, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Silva","sequence":"additional","affiliation":[{"name":"Department of HPB Surgery, Oxford University Hospital, Oxford, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2017,9,28]]},"reference":[{"key":"2025082707305242000_2017.sep28_1.bcr-2017-221191.1","doi-asserted-by":"publisher","DOI":"10.1007\/BF01300191"},{"key":"2025082707305242000_2017.sep28_1.bcr-2017-221191.2","doi-asserted-by":"publisher","DOI":"10.1148\/rg.263055164"},{"key":"2025082707305242000_2017.sep28_1.bcr-2017-221191.3","doi-asserted-by":"publisher","DOI":"10.1097\/SLA.0b013e3181a189a8"},{"key":"2025082707305242000_2017.sep28_1.bcr-2017-221191.4","doi-asserted-by":"publisher","DOI":"10.1016\/j.pan.2012.04.004"},{"key":"2025082707305242000_2017.sep28_1.bcr-2017-221191.5","doi-asserted-by":"crossref","first-page":"626","DOI":"10.1055\/s-0034-1391484","article-title":"The string sign for diagnosis of mucinous pancreatic cysts","volume":"47","author":"Bick","year":"2015","journal-title":"Endoscopy"},{"key":"2025082707305242000_2017.sep28_1.bcr-2017-221191.6","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjsurg.2005.01.025"},{"key":"2025082707305242000_2017.sep28_1.bcr-2017-221191.7","doi-asserted-by":"crossref","first-page":"105","DOI":"10.1080\/13651820310001144","article-title":"Choledochal cysts in adults and their complications","volume":"5","author":"Atkinson","year":"2003","journal-title":"HPB"},{"key":"2025082707305242000_2017.sep28_1.bcr-2017-221191.8","doi-asserted-by":"publisher","DOI":"10.1001\/archsurg.2011.243"},{"key":"2025082707305242000_2017.sep28_1.bcr-2017-221191.9","doi-asserted-by":"publisher","DOI":"10.1093\/jjco\/hyf093"},{"key":"2025082707305242000_2017.sep28_1.bcr-2017-221191.10","doi-asserted-by":"publisher","DOI":"10.1148\/radiol.09090992"},{"key":"2025082707305242000_2017.sep28_1.bcr-2017-221191.11","unstructured":"Shih H-S , S-f K , Chaung J-H .
