CTICasesCystic emphysema
Imaging findings
Chest CT shows multiple large, thin-walled cystic spaces throughout the lungs containing surviving vessels and residual tissue strands running through the lucent spaces.
Key takeaways
Cystic emphysema represents a severe form of centrilobular emphysema where the destroyed lung parenchyma forms large cystic spaces. The presence of surviving vessels and tissue strands within the lucencies is a key feature distinguishing emphysema from true cystic lung diseases.
