Foreign Body Aspiration: Imaging Aspects

摘要: Foreign body aspiration is the most frequent pediatric domestic accident, and has serious sometimes fatal sequelae. Most cases occur under age of 4 years. The history choking followed by persistent cough reliable clue for diagnosis, but many patients present with various nonspecific clinical symptoms. When a foreign definite, bronchoscopy modality choice both diagnosis management. In absence such can be overlooked, children unresolved pneumonia, atelectasis, or other complications. role radiologist in not only to confirm clinically suspected also suggest symptoms radiologic features that could related long-standing bodies. Many imaging findings are result one-way obstruction mechanism. A normal inspiratory chest radiograph does rule out body. Expiratory films important demonstrate air-trapping. high kilo-voltage (kV) copper filter technique valuable demonstrating nonopaque body, fluoroscopy very useful. Computed Tomography (CT) become more virtue its wide availability, resolution, multiplanar, three-dimensional additional image reconstruction capabilities. CT indicate exact location alternative diagnoses, any associated modalities as well established. An understanding mechanisms their resultant manifestations, lead earlier lower complication rate. This chapter discusses techniques types complications aspiration.
