We report a case of a 7\u2010year\u2010old boy who sustained blunt scrotal trauma from a bicycle accident. Ultrasound revealed a parenchymal defect with absent perfusion in the lower pole of the right testis at the site of impact, as well as a smaller lesion and subcapsular hematoma in the upper pole, opposite the point of trauma. Surgical exploration confirmed necrosis of the devascularized segment, leading to partial orchiectomy and drainage of the hematoma. The pattern of injury suggests a coup\u2013countercoup\u2010type mechanism, similar to that observed in traumatic brain injury, likely caused by internal displacement forces within the confined tunica albuginea. Prompt surgical intervention enabled preservation of viable testicular tissue. This case emphasizes the utility of high\u2010resolution ultrasound in detecting complex testicular injuries and highlights the need to consider contralateral damage in pediatric blunt scrotal trauma.<\/jats:p>","DOI":"10.1002\/jcu.70287","type":"journal-article","created":{"date-parts":[[2026,6,5]],"date-time":"2026-06-05T04:10:49Z","timestamp":1780632649000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Coup\u2013Countercoup Pattern in Pediatric Testicular Trauma: A Case Report"],"prefix":"10.1002","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-2446-6348","authenticated-orcid":false,"given":"Halil Ibrahim","family":"Altunbulak","sequence":"first","affiliation":[{"name":"Radiology Department Ministry Health, Tatvan State Hospital  Bitlis Turkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emre","family":"Boz","sequence":"additional","affiliation":[{"name":"Radiology Department Ministry Health, Mus State Hospital  Mus Turkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,6,4]]},"reference":[{"key":"e_1_2_14_2_1","doi-asserted-by":"publisher","DOI":"10.1177\/1742271x14545911"},{"key":"e_1_2_14_3_1","doi-asserted-by":"publisher","DOI":"10.1155\/2019\/7058728"},{"key":"e_1_2_14_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/0090\u20104295(91)80317\u2010z"},{"key":"e_1_2_14_5_1","doi-asserted-by":"publisher","DOI":"10.1053\/j.sult.2012.11.010"},{"issue":"2","key":"e_1_2_14_6_1","doi-asserted-by":"crossref","first-page":"357","DOI":"10.1148\/rg.272065117","article-title":"US of Acute Scrotal Trauma: Optimal Technique, Imaging Findings, and Management","volume":"27","author":"Deurdulian C.","year":"2007","journal-title":"Radiographics"},{"key":"e_1_2_14_7_1","doi-asserted-by":"publisher","DOI":"10.1385\/ncc:1:3:385"},{"key":"e_1_2_14_8_1","doi-asserted-by":"publisher","DOI":"10.7759\/cureus.41609"},{"key":"e_1_2_14_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjsurg.2012.10.021"},{"key":"e_1_2_14_10_1","doi-asserted-by":"publisher","DOI":"10.5489\/cuaj.6840"},{"key":"e_1_2_14_11_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11255\u2010016\u20101402\u20100"},{"issue":"5","key":"e_1_2_14_12_1","doi-asserted-by":"crossref","DOI":"10.21037\/tau-19-815","article-title":"Partial Orchiectomy vs. Radical Orchiectomy for Pediatric Testis Tumors","volume":"9","author":"Woo L.
