Imaging findings
Current and comparison radiographs, along with a corresponding coronal CT, showed strikingly asymmetric interstitial lung fibrosis. The findings were pretty typical of fibrosis but notably asymmetric, particularly in one lung.
Key takeaways
This is a nice example of strikingly unilateral asymmetric interstitial lung fibrosis in the context of systemic sclerosis. Theories about the cause include chronic microaspiration due to GE reflux in patients who sleep predominantly on one side, but the exact reason for such asymmetry is often unknown.
