The patient experienced a sudden onset of upper abdominal pain. Contrast-enhanced abdominal computed tomography (CT) showed an iso- to hyper-enhancing area mainly ranging from the dorsal aspect of the pancreatic head to the retroperitoneum around the right kidney. Abdominal angiography revealed marked stenosis in the origin of the celiac artery caused by MALS and a 7-mm saccular aneurysm in the AOB. Thus, we diagnosed the pain as having been caused by aneurysm rupture in the AOB due to MALS. The patient\u2019s symptoms and anemia also improved to normal range without surgery. Careful follow-up, considering possible recurrence of aneurysm at other sites in the future, is essential.<\/jats:p>","DOI":"10.1177\/1179547619828716","type":"journal-article","created":{"date-parts":[[2019,2,7]],"date-time":"2019-02-07T06:30:14Z","timestamp":1549521014000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":10,"title":["Retroperitoneal Hematoma: Rupture of Aneurysm in the Arc of B\u00fchler Caused by Median Arcuate Ligament Syndrome"],"prefix":"10.1177","volume":"12","author":[{"given":"Keiichiro","family":"Abe","sequence":"first","affiliation":[{"name":"Department of Gastroenterology, Dokkyo Medical University, Mibu, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Makoto","family":"Iijima","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Dokkyo Medical University, Mibu, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3716-3386","authenticated-orcid":false,"given":"Keiichi","family":"Tominaga","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Dokkyo Medical University, Mibu, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Satoshi","family":"Masuyama","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Dokkyo Medical University, Mibu, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Naoya","family":"Izawa","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Dokkyo Medical University, Mibu, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuichi","family":"Majima","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Dokkyo Medical University, Mibu, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Atsushi","family":"Irisawa","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Dokkyo Medical University, Mibu, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2019,2,7]]},"reference":[{"key":"bibr1-1179547619828716","doi-asserted-by":"publisher","DOI":"10.1007\/s100169900155"},{"key":"bibr2-1179547619828716","first-page":"185","volume":"32","author":"B\u00fchler A.","year":"1904","journal-title":"Gegenbaurs Morph Jb"},{"key":"bibr3-1179547619828716","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejvs.2006.12.021"},{"key":"bibr4-1179547619828716","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9610(00)00380-9"},{"key":"bibr5-1179547619828716","first-page":"165","volume":"91","author":"Janssen L","year":"1991","journal-title":"Acta Chir Belg"},{"key":"bibr6-1179547619828716","doi-asserted-by":"publisher","DOI":"10.1002\/ca.22773"},{"key":"bibr7-1179547619828716","doi-asserted-by":"publisher","DOI":"10.1007\/s00276-015-1478-8"},{"key":"bibr8-1179547619828716","doi-asserted-by":"publisher","DOI":"10.1007\/s002619900199"},{"key":"bibr9-1179547619828716","doi-asserted-by":"publisher","DOI":"10.1097\/00000658-198702000-00004"},{"key":"bibr10-1179547619828716","doi-asserted-by":"publisher","DOI":"10.1016\/j.avsg.2006.05.001"}],"container-title":["Clinical Medicine Insights: Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1179547619828716","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/1179547619828716","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1179547619828716","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T09:13:37Z","timestamp":1777454017000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/1179547619828716"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,1]]},"references-count":10,"alternative-id":["10.1177\/1179547619828716"],"URL":"https:\/\/doi.org\/10.1177\/1179547619828716","relation":{},"ISSN":["1179-5476","1179-5476"],"issn-type":[{"value":"1179-5476","type":"print"},{"value":"1179-5476","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,1]]},"article-number":"1179547619828716"}}
