Even though it is seen more often in children, its incidence in adults is even rarer. Clinical presentations can vary depending on its site and inherent tumour properties. The colon is an uncommon site for IMT and pyrexia of unknown origin (PUO) as its dominant clinical presentation is even rarer. A 27-year-old woman presented with PUO. She was evaluated under the department of internal medicine before undergoing an 18F-fluorodeoxyglucose positron emission tomography-computed tomography scan. This showed an intensely enhancing descending colon mass. An image-guided biopsy of this lesion was reported as IMT. She underwent a left hemicolectomy and complete excision of the tumour, following which her symptoms resolved completely. The patient has been disease-free at a 6-month follow-up and is asymptomatic at 1\u2009year.<\/jats:p>","DOI":"10.1136\/bcr-2020-236056","type":"journal-article","created":{"date-parts":[[2020,12,9]],"date-time":"2020-12-09T14:14:19Z","timestamp":1607523259000},"page":"e236056","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Colonic inflammatory myofibroblastic tumour presenting as \u2018pyrexia of unknown origin\u2019: report of a rare disease and its unique presentation."],"prefix":"10.1136","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6669-2957","authenticated-orcid":false,"given":"Victor Vijay","family":"Coelho","sequence":"first","affiliation":[{"name":"General Surgery, Christian Medical College and Hospital, Vellore, Tamil Nadu, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4836-9432","authenticated-orcid":false,"given":"Suraj","family":"Surendran","sequence":"additional","affiliation":[{"name":"General and Upper Gastrointestinal Surgery, Christian Medical College and Hospital, Vellore, Tamil Nadu, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Beulah","family":"Roopavathana","sequence":"additional","affiliation":[{"name":"General Surgery Unit IV, Christian Medical College and Hospital, Vellore, Tamil Nadu, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Suchita","family":"Chase","sequence":"additional","affiliation":[{"name":"General Surgery Unit IV, Christian Medical College and Hospital, Vellore, Tamil Nadu, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2020,12,9]]},"reference":[{"key":"2025082709453045000_13.12.e236056.1","doi-asserted-by":"publisher","DOI":"10.1016\/j.prp.2009.09.002"},{"key":"2025082709453045000_13.12.e236056.2","doi-asserted-by":"publisher","DOI":"10.4174\/jkss.2012.82.1.45"},{"key":"2025082709453045000_13.12.e236056.3","doi-asserted-by":"crossref","first-page":"141","DOI":"10.1016\/j.ijscr.2019.06.012","article-title":"Inflammatory myofibroblastic tumor of the transverse colon with synchronous gastrointestinal stromal tumor in a patient with ulcerative colitis: a case report","volume":"60","author":"Raffaeli","year":"2019","journal-title":"Int J Surg Case Rep"},{"key":"2025082709453045000_13.12.e236056.4","doi-asserted-by":"crossref","first-page":"136","DOI":"10.3748\/wjg.14.136","article-title":"Exophytic inflammatory myofibroblastic tumor of the stomach in an adult woman: a rare cause of hemoperitoneum","volume":"14","author":"Park","year":"2008","journal-title":"World J Gastroenterol"},{"key":"2025082709453045000_13.12.e236056.5","doi-asserted-by":"crossref","first-page":"1566","DOI":"10.3892\/ol.2014.1942","article-title":"Fever of unknown origin as a presentation of colonic inflammatory myofibroblastic tumor in a 36-year-old female: a case report","volume":"7","author":"Zhou","year":"2014","journal-title":"Oncol Lett"},{"key":"2025082709453045000_13.12.e236056.6","doi-asserted-by":"crossref","first-page":"119","DOI":"10.1016\/S0096-5588(20)32030-4","article-title":"Two interesting benign lung tumors of contradictory histopathology; remarks on necessity for maintaining chest tumor registry","volume":"9","author":"Brunn","year":"1939","journal-title":"J Thorac Surg"},{"key":"2025082709453045000_13.12.e236056.7","unstructured":"Coffin CM , Fletcher JA .
