A 76\u2010year\u2010old Japanese man presented to our hospital with a 1\u2010year history of worsening diarrhea, lower abdominal pain, and weight loss (\u22126 kg). Laboratory evaluation revealed white blood cell count of 13\u2009200\/\u03bcL, C\u2010reactive protein level of 2.0\u2009mg\/dL (normal range, 0.0\u20130.3), and negative results for stool culture (including <jats:italic>Clostridium difficile<\/jats:italic>). Colonoscopy showed circumferential and edematous narrowing of the sigmoid colon with deep longitude ulceration. Biopsy was done and examination of the specimen demonstrated no specific ischemia. The patient was treated with bowel rest, antibiotics, and i.v. fluids; however, his symptoms worsened. Finally, sigmoidectomy was carried out. Histological examination demonstrated significant myointimal hyperplasia of mesenteric veins leading to thickening and stenosis of the venous lumen. Therefore, the final diagnosis was IMHMV. Three months following sigmoidectomy, he was asymptomatic.<\/jats:p>","DOI":"10.1111\/den.12470","type":"journal-article","created":{"date-parts":[[2015,3,17]],"date-time":"2015-03-17T00:10:57Z","timestamp":1426551057000},"page":"768-771","source":"Crossref","is-referenced-by-count":23,"title":["Idiopathic myointimal hyperplasia of mesenteric veins: Rare case of ischemic colitis mimicking inflammatory bowel disease"],"prefix":"10.1111","volume":"27","author":[{"given":"Kota","family":"Sahara","sequence":"first","affiliation":[{"name":"Department of Surgery, Tokyo Metropolitan Cancer and Infectious Diseases Center Komagome Hospital  Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rin","family":"Yamada","sequence":"additional","affiliation":[{"name":"Department of Pathology, Tokyo Metropolitan Cancer and Infectious Diseases Center Komagome Hospital  Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takashi","family":"Fujiwara","sequence":"additional","affiliation":[{"name":"Department of Gastroenterological Medicine, Tokyo Metropolitan Cancer and Infectious Diseases Center Komagome Hospital  Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Koichi","family":"Koizumi","sequence":"additional","affiliation":[{"name":"Department of Gastroenterological Medicine, Tokyo Metropolitan Cancer and Infectious Diseases Center Komagome Hospital  Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shin\u2010ichiro","family":"Horiguchi","sequence":"additional","affiliation":[{"name":"Department of Pathology, Tokyo Metropolitan Cancer and Infectious Diseases Center Komagome Hospital  Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tsunekazu","family":"Hishima","sequence":"additional","affiliation":[{"name":"Department of Pathology, Tokyo Metropolitan Cancer and Infectious Diseases Center Komagome Hospital  Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tatsuro","family":"Yamaguchi","sequence":"additional","affiliation":[{"name":"Department of Surgery, Tokyo Metropolitan Cancer and Infectious Diseases Center Komagome Hospital  Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2015,4,22]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/0016-5085(91)90035-J"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00384-012-1480-0"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0016-5085(03)00663-2"},{"key":"e_1_2_5_5_1","first-page":"e54","article-title":"A rare cause of ischemic proctosigmoiditis: idiopathic myointimal hyperplasia of mesenteric veins","volume":"44","author":"Chiang CK","year":"2014","journal-title":"Endoscopy"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-199610000-00014"},{"key":"e_1_2_5_7_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF02236711"},{"key":"e_1_2_5_8_1","doi-asserted-by":"publisher","DOI":"10.1097\/00004836-200509000-00011"},{"key":"e_1_2_5_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.crohns.2010.12.003"},{"key":"e_1_2_5_10_1","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-199408000-00003"}],"container-title":["Digestive Endoscopy"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fden.12470","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/den.12470","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,3]],"date-time":"2023-10-03T03:58:12Z","timestamp":1696305492000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/den.12470"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,4,22]]},"references-count":9,"journal-issue":{"issue":"7","published-print":{"date-parts":[[2015,11]]}},"alternative-id":["10.1111\/den.12470"],"URL":"https:\/\/doi.org\/10.1111\/den.12470","archive":["Portico"],"relation":{},"ISSN":["0915-5635","1443-1661"],"issn-type":[{"value":"0915-5635","type":"print"},{"value":"1443-1661","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015,4,22]]}}}
