Shortly following his birth, a congenital oesophageal atresia had been managed surgically with colonic interposition graft. Contrast CT of the neck revealed filling and distention of a colic stump with content of stasis and infection. The patient received intravenous piperacillin\/tazobactam and parenteral nutrition. One week later, an upper digestive endoscopy was performed revealing an inflammatory-looking pseudopolypoid area immediately below the anastomosis, at the level of the proximal portion of the colon, which seemed to correspond to a complicated diverticulum with inflammation. The difficulties in reaching a definitive diagnosis and management of this condition are discussed.<\/jats:p>","DOI":"10.1136\/bcr-2022-249119","type":"journal-article","created":{"date-parts":[[2022,9,20]],"date-time":"2022-09-20T11:51:35Z","timestamp":1663674695000},"page":"e249119","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Cervical inflammatory mass: a very late complication following neonatal oesophagocoloplasty for oesophageal atresia"],"prefix":"10.1136","volume":"15","author":[{"given":"Mariana","family":"Lemos","sequence":"first","affiliation":[{"name":"General Surgery, Centro Hospitalar e Universitario de Coimbra EPE, Coimbra, Portugal"},{"name":"Faculdade de Medicina, Universidade de Coimbra, Coimbra, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mariana","family":"Duque","sequence":"additional","affiliation":[{"name":"General Surgery, Centro Hospitalar e Universitario de Coimbra EPE, Coimbra, Portugal"},{"name":"Faculdade de Medicina, Universidade de Coimbra, Coimbra, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3910-845X","authenticated-orcid":false,"given":"Andre","family":"Lazaro","sequence":"additional","affiliation":[{"name":"Faculdade de Medicina, Universidade de Coimbra, Coimbra, Portugal"},{"name":"General Surgery -
