They are detected on unenhanced x-rays in less than 10% of patients with appendicitis. When an appendicolith is found extraluminally, it is pathognomonic for perforation of the appendix. Moreover, retained appendicoliths act as a nidus for infection and are likely to be the source of a postoperative intraperitoneal abscess. However, this is very rare with only 30 reported cases of intra-abdominal abscess secondary to an appendicolith in the literature over the past 40 years.<\/jats:p>\n                  <jats:p>Retained, or dropped, appendicoliths most commonly present as an area of high attenuation less than 1cm in diameter with an associated abscess close to the caecum or Morrison\u2019s pouch on computed tomography (CT). A study published in 2006 showed that although there is initial success with CT-guided drainage of abscesses secondary to faecaliths, all will recur and formal surgical drainage with removal of the appendicolith is required.<\/jats:p>\n                  <jats:p>This case report highlights not only an unusual complication of a retained appendicolith but also the importance of taking a thorough history and interpreting investigations in the context of the patient\u2019s past medical history so as to produce a differential diagnosis and prevent treatment of incorrect conditions.<\/jats:p>","DOI":"10.1308\/147870811x591701","type":"journal-article","created":{"date-parts":[[2011,8,29]],"date-time":"2011-08-29T08:10:08Z","timestamp":1314605408000},"page":"e117-e118","source":"Crossref","is-referenced-by-count":5,"title":["A complication of a dropped appendicolith misdiagnosed as Crohn\u2019s disease"],"prefix":"10.1308","volume":"93","author":[{"given":"S","family":"Sarkar","sequence":"first","affiliation":[{"name":"East Kent Hospitals NHS Foundation Trust, Canterbury, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L","family":"Douglas","sequence":"additional","affiliation":[{"name":"Lancashire Teaching Hospitals NHS Foundation Trust, Preston, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"AA","family":"Egun","sequence":"additional","affiliation":[{"name":"Lancashire Teaching Hospitals NHS Foundation Trust, Preston, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"171","reference":[{"key":"p_1","doi-asserted-by":"publisher","DOI":"10.1089\/lap.2007.0152"},{"key":"p_2","first-page":"127","volume":"55","author":"Tsai HM","year":"2008","journal-title":"Hepatogastroenterology"},{"key":"p_3","doi-asserted-by":"publisher","DOI":"10.1007\/s10140-007-0613-1"},{"key":"p_4","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejrad.2006.06.003"}],"container-title":["The Annals of The Royal College of Surgeons of England"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/publishing.rcseng.ac.uk\/doi\/pdf\/10.1308\/147870811X591701","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,5,15]],"date-time":"2023-05-15T05:53:21Z","timestamp":1684130001000},"score":1,"resource":{"primary":{"URL":"https:\/\/publishing.rcseng.ac.uk\/doi\/10.1308\/147870811X591701"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011,9]]},"references-count":4,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2011,9]]}},"alternative-id":["10.1308\/147870811X591701"],"URL":"https:\/\/doi.org\/10.1308\/147870811x591701","relation":{},"ISSN":["0035-8843","1478-7083"],"issn-type":[{"value":"0035-8843","type":"print"},{"value":"1478-7083","type":"electronic"}],"subject":[],"published":{"date-parts":[[2011,9]]}}}
