CTICasesPlastic bronchitis
Imaging findings
CT scans over several years show persistent, confluent ground-glass opacities in the right middle lobe and lower lobes. Surgical lung biopsy was non-diagnostic. Clinical history and photographs confirm the expectoration of large, branching bronchial casts.
Key takeaways
Plastic bronchitis is a rare condition characterized by the formation of large, cohesive bronchial casts that obstruct the airway. While classically seen in children post-Fontan surgery or in asthma, idiopathic adult cases occur and can be difficult to diagnose without inspecting expectorated sputum.
