MRI and CT imaging demonstrated a 5.8\u2009cm unilocular cyst containing a fluid-fluid level within the mesentery. Following an uncomplicated open excision, the lesion was characterised by pathology as a cystic lymphangioma due to the presence of focal smooth muscle and lymphoid tissue in the wall. This case report discusses the radiologic features of rare lymphatic mesenteric cysts that can help guide preoperative diagnosis and highlights that postoperative diagnosis remains definitive. This case also underscores the importance of considering mesenteric cysts as a rare cause of abdominal pain in patients who have non-specific abdominal symptoms and a mass on imaging not associated with any single organ.<\/jats:p>","DOI":"10.1136\/bcr-2024-261472","type":"journal-article","created":{"date-parts":[[2024,11,12]],"date-time":"2024-11-12T13:05:13Z","timestamp":1731416713000},"page":"e261472","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Symptomatic presentation and imaging features of a chylous cystic lymphangioma"],"prefix":"10.1136","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0452-8000","authenticated-orcid":false,"given":"Lily","family":"Kwak","sequence":"first","affiliation":[{"name":"The Johns Hopkins University School of Medicine, Baltimore, Maryland, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matteen","family":"Hakim","sequence":"additional","affiliation":[{"name":"Department of Radiology, The Johns Hopkins University School of Medicine, Baltimore, Maryland, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gabriel","family":"Ivey","sequence":"additional","affiliation":[{"name":"Department of Surgery, The Johns Hopkins University School of Medicine, Baltimore, Maryland, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1192-3084","authenticated-orcid":false,"given":"Claire","family":"Brookmeyer","sequence":"additional","affiliation":[{"name":"Department of Radiology, The Johns Hopkins University School of Medicine, Baltimore, Maryland, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2024,11,12]]},"reference":[{"key":"2025082801520522000_17.11.e261472.1","doi-asserted-by":"publisher","DOI":"10.1001\/archsurg.1984.01390190076018"},{"key":"2025082801520522000_17.11.e261472.2","doi-asserted-by":"publisher","DOI":"10.1159\/000018872"},{"key":"2025082801520522000_17.11.e261472.3","doi-asserted-by":"crossref","first-page":"1368","DOI":"10.1148\/rg.2021200207","article-title":"Approach to Cystic Lesions in the Abdomen and Pelvis, with Radiologic-Pathologic Correlation","volume":"41","author":"Yacoub","year":"2021","journal-title":"Radiographics"},{"key":"2025082801520522000_17.11.e261472.4","doi-asserted-by":"publisher","DOI":"10.1111\/j.1445-2197.1994.tb04530.x"},{"key":"2025082801520522000_17.11.e261472.5","first-page":"176","article-title":"Lymphangioma of the Mesentery: Case Report and Review of the Literature","volume":"28","author":"Gendvilait\u0117","year":"2021","journal-title":"Acta Med Litu"},{"key":"2025082801520522000_17.11.e261472.6","doi-asserted-by":"crossref","first-page":"469","DOI":"10.1016\/j.ijscr.2014.05.008","article-title":"Giant chylolymphatic mesenteric cyst and its successful enucleation: A case report","volume":"5","author":"Al Booq","year":"2014","journal-title":"Int J Surg Case Rep"},{"key":"2025082801520522000_17.11.e261472.7","doi-asserted-by":"crossref","DOI":"10.1093\/jscr\/rjad320","article-title":"A giant chylolymphatic cyst of the retroperitoneum: a case report","volume":"2023","author":"Alafandi","year":"2023","journal-title":"J Surg Case Rep"},{"key":"2025082801520522000_17.11.e261472.8","doi-asserted-by":"publisher","DOI":"10.1148\/rg.252045108"},{"key":"2025082801520522000_17.11.e261472.9","article-title":"Cystic Lymphangioma: Are Triglycerides Always Measurable?","volume":"2018","author":"Fran\u00e7ois","year":"2018","journal-title":"Case Rep Gastrointest Med"},{"key":"2025082801520522000_17.11.e261472.10","doi-asserted-by":"crossref","DOI":"10.14309\/00000434-201110002-00568","article-title":"Utility of EUS in Diagnosing a Retroperitoneal Lymphangioma Masquerading as a Pancreatic Cyst","volume":"106","author":"Dang","year":"2011","journal-title":"Am J Gastroenterol"},{"key":"2025082801520522000_17.11.e261472.11","doi-asserted-by":"publisher","DOI":"10.5301\/jbm.5000257"},{"key":"2025082801520522000_17.11.e261472.12","doi-asserted-by":"publisher","DOI":"10.1001\/archsurg.1985.01390350048010"},{"key":"2025082801520522000_17.11.e261472.13","doi-asserted-by":"crossref","DOI":"10.1186\/1752-1947-3-111","article-title":"Pediatric chylolymphatic mesenteric cyst -
