Post pneumotic pneumatocoele

Case contributed by Assoc Prof Frank Gaillard


Recent chest infection. Now gradually improving.

Patient Data

Age: 2 1/2 years
Gender: Male

Chest x-ray

There is a well circumscribed rounded cystic mass in the right upper lobe.  The walls are moderately thick and there is an air-fluid level. 


CT chest

Confirmation of the chest radiograph findings.  Right upper lobe air-cyst with moderately thick walls - the previously demonstrated air-fluid level is no longer apparent.

The background lung parenchyma appears normal on these selected slices although movement artefact is present.

Case Discussion

The chest radiograph and CT confirm a cystic lesion in the right upper lobe.  On the CXR, there is an air-fluid level - this has resolved by the time of CT.

The differential is that of a cystic lung lesion in a child.  Features are of a post-pneumotic pneumatocoele in a 2 1/2 year old child.
