The management goal is to control infection while preserving the implanted device. A 2\u2010year\u2010old boy with cochlear implants developed acute mastoiditis and a subsequent retroauricular abscess. The patient underwent a surgical intervention based on the diagnosis made utilizing gray\u2010scale and power Doppler sonography. This case illustrates the diagnostic usefulness of sonography in this rare situation. \u00a9 2017 Wiley Periodicals, Inc. <jats:italic>J Clin Ultrasound<\/jats:italic> <jats:bold>45<\/jats:bold>:515\u2013519, 2017<\/jats:p>","DOI":"10.1002\/jcu.22442","type":"journal-article","created":{"date-parts":[[2017,4,5]],"date-time":"2017-04-05T11:19:35Z","timestamp":1491391175000},"page":"515-519","source":"Crossref","is-referenced-by-count":3,"title":["Sonographic diagnosis of acute mastoiditis and subsequent retroauricular abscess in a pediatric cochlear implant recipient: A case report"],"prefix":"10.1002","volume":"45","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9431-3301","authenticated-orcid":false,"given":"Hiroshi","family":"Sakaida","sequence":"first","affiliation":[{"name":"Department of Otorhinolaryngology\u2013Head &amp;
