Describe and interpret this CXR and clinical image
There is diffuse reticulonodular infiltrate across all lung fields, but most marked in the bases.
*There is loss of volume in both lung fields *
The appearances are consistent with pulmonary fibrosis
This is clubbing
In this case, this patient has developed signs of cor pulmonale secondary to the chronic lung disease.
Bi-basal inspiratory crackles can be commonly miss-labelled as pulmonary oedema, particularly when there is right heart failure.
The presence of clubbing (present in ~50% cases of idiopathic pulmonary fibrosis) should be a strong driver towards considering a primary pulmonary pathology.
Idiopathic Pulmonary Fibrosis has replaced the term ‘cryptogenic fibrosing alveolitis’.
Note: it is only idiopathic when you have excluded the multitude of causes of pulmonary fibrosis, so unless you have taken a full occupational, environmental, smoking and drug exposure history, family history, together with screening for (occult) connective tissue disease, its safer just to call it ‘pulmonary fibrosis‘, and let someone else worry about what sub-type (at least 7 and counting) and what cause!
