Intravenous and Intracavitary Use of Contrast‐Enhanced Ultrasound in the Evaluation and Management of Complicated Pediatric Pneumonia

Abstract

Pediatric pneumonia can be complicated by necrotizing pneumonia or a parapneumonic effusion either in the form of an empyema or a clear effusion. Ultrasonography (US) and computed tomography represent well-established modalities for evaluation of complicated pediatric pneumonia. Contrast-enhanced ultrasound (CEUS) was recently introduced and is gaining increasing acceptance in pediatric imaging. In this case series, we present our initial experience with both intravenous and intracavitary use of CEUS in children with complicated pneumonia. Intravenous CEUS accurately and confidently showed necrotizing pneumonia and delineated pleural effusions, whereas intracavitary CEUS accurately identified the chest catheter location and patency and showed the presence of loculations, suggesting the use of fibrinolytics.
