CTICasesMucinous Adenocarcinoma Mimicking Interstitial Lung Disease
Imaging findings
In a 78-year-old referred for suspected interstitial lung disease, the only available CT shows mild emphysema and debatable honeycombing, together with asymmetric consolidation and ground-glass opacity in the left lower lobe. An outside transbronchial biopsy was initially negative; multidisciplinary review prompted a repeat transbronchial biopsy given the asymmetry, which identified a cluster of atypical cells.
Key takeaways
Asymmetric consolidation and ground-glass opacity in a patient referred for suspected interstitial lung disease should raise concern for an underlying mucinous adenocarcinoma masquerading as fibrosis, particularly when the abnormality is asymmetric rather than the typically symmetric, basal-predominant pattern of usual interstitial pneumonia -- a repeat, more targeted biopsy confirmed adenocarcinoma after an initial negative sampling.
