Congenital pulmonary airway malformation

Case contributed by Dr Jeremy Jones


Respiratory distress but no features of infection or sepsis.

Patient Data

Age: 10 months
Gender: Male

2 1/2 months old

Modality: X-ray

The mediastinum is shifted to the left due to hyperexpansion of the right lung.  The cardiothymic contour is normal.

10 months old

Modality: X-ray

The right lung, which is relatively oligaemic, has increased in volume with subsequent mediastinal shift.

Modality: CT

There is a large area of abnormal hyper-expanded oligaemic lung parenchyma in the anterior portion of the right lung.  The mediastinum is displaced by the mass-effect it produces.

The abnormal lung is not restricted by normal boundaries and crosses the oblique fissure.

Case Discussion

Congenital pulmonary airway malformations are complex pulmonary anomalies that can have a broad range of appearances.

They may result in grossly cystic abnormalities, or, as in this case, result in a more generalised emphysematous appearance.  They may cross the normal boundaries within the lung and exist on either side of the major and minor fissures.
