RT Journal Article SR Electronic T1 Cervical inflammatory mass: a very late complication following neonatal oesophagocoloplasty for oesophageal atresia JF BMJ Case Reports JO BMJ Case Reports FD BMJ Publishing Group Ltd SP e249119 DO 10.1136/bcr-2022-249119 VO 15 IS 9 A1 Mariana Lemos A1 Mariana Duque A1 Andre Lazaro A1 António Bernardes YR 2022 UL http://casereports.bmj.com/content/15/9/e249119.abstract AB We report the case of a man in his 40s who presented to our emergency department with a history of fever and a red, swollen and painful neck mass. 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.
