1) Understand the clinical presentations and imaging appearances of the more common types of extra pulmonary thoracic masses that occur in children. 2) Appreciate the potential for life-threatening symptomatology associated with imaging some of these children. 3) A tailored approach to multi-planar imaging of these masses, initially guided by the conventional chest radiograph. 4) Incorporate the “ALARA” principles into Multi-planar Imaging, while understanding that many of these masses permit diagnostic investigations that require little or no radiation.
Imaging of pediatric extra-pulmonary tumors has undergone revolutionary changes in recent years with the realization that many lesions are better imaged with modalities other than chest computed tomography. The widespread acceptance of the “Image Gently” campaign has resulted in a quest for diagnostic imaging algorithms that minimize radiation exposure throughout Pediatrics. Yet the correct initial imaging studies in children with thoracic masses can be critical in light of the potential for immediate airway and vascular compromise, especially with the use of sedation/anesthesia that is inherent to many extra-pulmonary masses in children. We will review many of the more common thoracic wall and mediastinal masses in children, with the aim of directing an appropriate and safe imaging algorithm for radiological investigation of these children.
