CTICasesDynamic Free-Breathing CT Airway Evaluation Demonstrating Severe Tracheomalacia
Imaging findings
In an infant with a tracheoesophageal fistula, free-breathing volumetric cine CT of the airway -- performed without sedation using a wide-detector scanner -- shows a dilated, fluid-filled esophagus and severe anterior tracheal collapse during the respiratory cycle at the level of the missing tracheal cartilage/vessel impression, confirmed on optical bronchoscopy.
Key takeaways
A free-breathing, low-radiation-dose (DLP roughly 30-40) cine CT acquisition can directly demonstrate the dynamic severity and extent of tracheomalacia in an infant with a tracheoesophageal fistula without requiring sedation or general anesthesia, providing surgeons a functional roadmap for airway stenting or splinting procedures.
