His physical exam was significant for rebound, guarding, and tenderness in the right lower quadrant, and his labs demonstrated a leukocytosis. Both a point-of-care ultrasound and radiology-performed ultrasound were concerning for acute appendicitis with a periappendiceal abscess, but on emergent laparoscopy the patient was found to have an infected urachal cyst.\nDiscussion: Infected urachal remnants are a rare but important cause of pediatric abdominal pain. In this case, inflammation surrounding the patient\u2019s midline urachal cyst triggered a serositis that involved the appendix and pulled the cyst to the right. This created a clinical and radiologic presentation similar to appendicitis. This atypical presentation of an already rare anomaly highlights the importance of maintaining a broad differential during the work-up of pediatric abdominal pain.<\/jats:p>","DOI":"10.5811\/cpcem.2022.1.55243","type":"journal-article","created":{"date-parts":[[2022,5,28]],"date-time":"2022-05-28T14:24:17Z","timestamp":1653747857000},"page":"186-188","source":"Crossref","is-referenced-by-count":1,"title":["Infected Urachal Cyst Masquerading as Acute Appendicitis on Point-of-care Ultrasound"],"prefix":"10.5811","volume":"6","author":[{"given":"Victoria","family":"Quinn","sequence":"first","affiliation":[{"name":"Brown University Warren Alpert Medical School, Hasbro Children\u2019s Hospital,  Department of Pediatrics, Providence, Rhode Island"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francois","family":"Luks","sequence":"additional","affiliation":[{"name":"Brown University Warren Alpert Medical School, Hasbro Children\u2019s Hospital, Division  of Pediatric Surgery, Providence, Rhode Island"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Erika","family":"Constantine","sequence":"additional","affiliation":[{"name":"Brown University Warren Alpert Medical School, Hasbro Children\u2019s Hospital, Department  of Pediatrics and Pediatric Emergency Medicine, Providence, Rhode Island"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"29705","published-online":{"date-parts":[[2022,5,5]]},"reference":[{"key":"ref0","doi-asserted-by":"publisher","unstructured":"Allen JW, Song J, Velcek FT.
