Adenocarcinoma of the lung mimicking interstitial lung disease

Abstract

Atypical radiologic and clinical patterns may be observed within subgroups of lung adenocarcinoma. A 74-year-old man with progressive dyspnea and productive cough unresponsive to antibiotherapy showed bilateral interstitial changes in the lung parenchyma on computed tomography. We here report a patient followed up with a prediagnosis of interstitial lung disease but eventually diagnosed with lung adenocarcinoma following transthoracic lung biopsy.
