CTICasesDiffuse Lepidic Adenocarcinoma
Imaging findings
Chest radiograph and CT show progressive, sheets of coalescent micronodules and consolidations throughout both lungs, mimicking miliary tuberculosis or coccidioidomycosis. Biopsy confirmed lepidic adenocarcinoma.
Key takeaways
Diffuse lepidic adenocarcinoma can present with widespread consolidations and coalescent micronodules mimicking miliary infection. A key clinical clue is the lack of acute infectious symptoms or systemic toxicity relative to the severity of imaging findings.
