Missed cancer in a patient known for UIP. A non-specific nodule/density at the frontier of the diseased/normal lung was not reported on the first CT scan (a). A significant increased size was subsequently observed at the follow-up CT scan 5 months later (b) with a histologically proven low differentiated lung carcinoma. Satisfaction of search which is mainly aimed at evaluating the ILD commonly overlook such focal and/or newly discovered suspicious abnormalities. ILD, interstitial lung disease; UIP, usual interstitial pneumonitis.
