Abdominal imaging in child abuse.

INTRODUCTION: Abdominal injuries in abused children are less common than musculoskeletal and craniocerebral injuries; however they carry high mortality and morbidity rates. In every case of trauma, regardless of aetiology, radiologists are responsible for the documentation and evaluation of injuries. INJURIES: Any abdominal injury pattern maybe observed following physical abuse and none is specific for abuse. However, a high index of suspicion should be maintained for every case of pancreatic, hollow viscous and other solid organ injuries, especially when there is delay in seeking help, a history of trauma to the child or siblings, young age, undernourishment, ecchymosis in non-ambulatory children or a non-plausible explanation for the injuries based on the provided history and the psychomotor condition of the child. IMAGING MODALITIES: CT with intravenous contrast material is the imaging modality of choice in every suspected inflicted abdominal injury. US could be the first imaging test for abused children with a low probability of abdominal injury and for follow-up. Upper gastrointestinal series could reveal acute or resolving mural haematomas in children with equivocal CT or US findings.
CONCLUSION: Child abuse should be considered in the differential diagnosis of acute abdominal symptoms in young children.
