CTICasesDiscrete Emphysema
Imaging findings
Presence of cystic-like lesions in a 46-year-old never-smoker from India. Lesions display internal architecture, webs, and vessels rather than being simple cysts. Biopsy confirmed emphysematous changes despite the atypical appearance.
Key takeaways
Termed "discrete emphysema," this condition may be a result of particulate air pollution or underlying tissue abnormalities (collagen/elastin issues). Some "walls" of these lesions are actually collapsed alveolar tissue forming pseudo-cysts.
