Paraseptal emphysema

Case contributed by Fazel Rahman Faizi
Diagnosis almost certain



Patient Data

Age: 25 years
Gender: Male

Numerous hyperlucent foci and bullae are seen in the subpleural distribution of both lungs, predominantly in the posterior lower lobes. Possible honeycombing and reticulation at the lowermost lungs, suggesting early fibrosis.

Case Discussion

At the histologic level, fibrosis is a common component of emphysema (see reference article).

Imaging findings of fibrosis can also coexist with those of emphysema. The abnormalities likely affect pulmonary function together.
