ObjectiveThe primary objective of this study is to assess common sites of injury and the associated imaging findings in penetrating injuries. We pay particular attention to gluteal, anterior abdominal wall and junctional zone injuries. The aim is to highlight areas of diagnostic uncertainty and discrepancy between imaging and surgical findings, to improve review areas in trauma reporting.MethodsA retrospective, observational study reviewing all paediatric admissions to the emergency department of a major trauma Centre with a penetrating injury, from 2015 to 2019.ResultsGluteal penetrating injuries are by far the most commonly sustained injury in the adolescent population, making up over 1/3 of cases. The vast majority of these cases sustained superficial injuries or shallow intramuscular haematomas, however in a small group (15%), serious vascular or rectal injuries were demonstrated on dual phase CT, requiring emergent surgical or endovascular treatment. Penetrating injuries to the anterior abdominal wall and junctional zone are less common but are associated with higher morbidity, with 43% of cases demonstrating solid organ or bowel injury. These cases also lead to an increased degree of diagnostic uncertainty.ConclusionGluteal injuries are common and although the overall morbidity of these cases is low, these patients are at risk of serious and life threatening consequences such as vascular and rectal injury and it is imperative that these complications are considered and ruled out via dual phase CT or direct visualization. Anterior abdominal wall and junctional zone injuries are less common, but lead to greater morbidity and also greater diagnostic uncertainty. The use of other salient findings as described in this report can aid diagnostic accuracy and reduce discrepancies.Copyright © 2024. Published by Elsevier Ltd.
