We report the case of a patient, initially thought to have ulcerative colitis (UC), who underwent such surgery but subsequently developed perianal CD. She presented with diarrhoea and weight loss. Inflammatory markers were raised. Pouchoscopy revealed deep ulcers within the pouch. The main differential diagnoses were idiopathic pouchitis and recurrent CD. However, immunohistochemical staining demonstrated positivity for cytomegalovirus (CMV). Stool frequency, C reactive protein and albumin normalised within 48\u2005h of starting oral valgancyclovir. At 15\u2005weeks, pouch appearances were improved, no histological evidence of CMV was found and baseline pouch function had returned. This case highlights that CD can present many years after surgery for apparent UC. Also, CMV pouchitis should be considered as a differential cause of pouchitis especially as it is treatable with antiviral therapy.<\/jats:p>","DOI":"10.1136\/bcr-2014-205374","type":"journal-article","created":{"date-parts":[[2014,7,18]],"date-time":"2014-07-18T01:49:57Z","timestamp":1405648197000},"page":"bcr2014205374","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":4,"title":["Cytomegalovirus pouchitis in a patient with Crohn's disease"],"prefix":"10.1136","volume":"2014","author":[{"given":"Nigel Tapiwa","family":"Mabvuure","sequence":"first","affiliation":[{"name":"Lister Department of Surgery, NHS Greater Glasgow and Clyde, Glasgow, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laura","family":"Maclean","sequence":"additional","affiliation":[{"name":"NHS Greater Glasgow and Clyde, Glasgow, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karin","family":"Oien","sequence":"additional","affiliation":[{"name":"NHS Greater Glasgow and Clyde, Glasgow, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel","family":"Gaya","sequence":"additional","affiliation":[{"name":"NHS Greater Glasgow and Clyde, Glasgow, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2014,7,17]]},"reference":[{"key":"2025082703350848000_2014.jul17_1.bcr2014205374.1","doi-asserted-by":"crossref","first-page":"113","DOI":"10.1007\/BF02237255","article-title":"Cytomegalovirus infection as a cause of ileoanal pouchitis","volume":"43","author":"Pfau","year":"2000","journal-title":"Dis Colon Rectum"},{"key":"2025082703350848000_2014.jul17_1.bcr2014205374.2","doi-asserted-by":"publisher","DOI":"10.1097\/MIB.0b013e318280ec71"},{"key":"2025082703350848000_2014.jul17_1.bcr2014205374.3","doi-asserted-by":"publisher","DOI":"10.1111\/j.1572-0241.1998.00264.x"},{"key":"2025082703350848000_2014.jul17_1.bcr2014205374.4","doi-asserted-by":"publisher","DOI":"10.1097\/MIB.0b013e3182a52553"},{"key":"2025082703350848000_2014.jul17_1.bcr2014205374.5","doi-asserted-by":"publisher","DOI":"10.1007\/BF02235196"},{"key":"2025082703350848000_2014.jul17_1.bcr2014205374.6","doi-asserted-by":"publisher","DOI":"10.3748\/wjg.v19.i1.17"},{"key":"2025082703350848000_2014.jul17_1.bcr2014205374.7","doi-asserted-by":"publisher","DOI":"10.1099\/jmm.0.45629-0"},{"key":"2025082703350848000_2014.jul17_1.bcr2014205374.8","doi-asserted-by":"publisher","DOI":"10.1038\/ajg.2009.530"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2014-205374","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T10:35:18Z","timestamp":1756290918000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2014-205374"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,7,17]]},"references-count":8,"alternative-id":["10.1136\/bcr-2014-205374"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2014-205374","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2014,7,17]]}}}
