Swyer-James-MacLeod Syndrome
Imaging findings
CT shows asymmetric lung attenuation, bronchial wall thickening, bronchiectasis, and air trapping/hyperlucency. The affected lung is of normal size, suggesting the insult occurred later in childhood.
Key takeaways
This is an asymmetric process, not truly unilateral. It is often misdiagnosed; it results from post-infectious constrictive bronchiolitis.
