Diagnostic Imaging in Nontraumatic Pediatric Head and Neck Emergencies

Abstract

Evaluation of pediatric patients in the emergency setting is complicated by a limited history and physical examination, which often produce findings that overlap with multiple disease processes. Imaging therefore plays a critical role in achieving an accurate and timely diagnosis. Knowledge of the typical clinical and imaging manifestations of common pediatric head and neck emergencies and congenital abnormalities allows the interpreting radiologist to identify the primary cause of the condition as well as any associated complications that may warrant immediate surgical management. The specific imaging protocol depends on the patient's clinical status. Radiography, ultrasonography, and contrast material-enhanced computed tomography all may be appropriate modalities for an initial examination. In especially difficult or complex cases, magnetic resonance imaging may offer additional detail with respect to the extent of disease.
