Paediatric groin lesions: Imaging findings

Objectives The groin is a complex anatomic region that has traditionally been ignored by radiologists because most lesions can be diagnosed from clinical data and physical examination. Nevertheless, ultrasound examinations of the groin are increasingly being requested to confirm injury or to resolve diagnostic uncertainty. On the other hand, some conditions involving the groin are found only in paediatric patients. This article describes the key imaging findings in paediatric groin injuries, placing special emphasis on the ultrasound appearance. Conclusions Knowledge about conditions that can affect the groin in paediatric patients and the key imaging findings associated with them helps improve the diagnostic performance of ultrasound.
