Pulmonary nodules are a frequent, incidental finding on CT scans, ranging from up to 8.4% on abdominal scans and up to 48% on CT angiograms. Incidental findings are sometimes disregarded or overshadowed by critical situations and may not be disclosed or documented on discharge. The costs and risks associated with incidental findings are not insignificant, including the risk of a delayed diagnosis of lung cancer. ⋯ Improvements with consistent use of Fleischner guidelines in scan reports by radiologists and increased ownership in informing patients of incidental nodules by ED and trauma providers have occurred. As the frequency of chest CT imaging is increasing, the number of incidental nodules identified will also increase. A lung nodule surveillance process would greatly benefit every lung nodule clinic or hospital system for management of pulmonary nodules.

A 63-year-old, non-smoking Asian woman presented to our hospital due to abnormal findings on chest radiography. She had no history of dust exposure. Chest radiography and CT imaging showed patchy ground-glass attenuation (GGA) in the bilateral lower lung lobes, a ground-glass nodule in the right lower lung lobe (diameter, 9.8 mm), and some thin-walled cysts in both lungs (Fig 1). ⋯ Simultaneously, the lung background showed diffuse lymphocytic infiltration in the alveolar septum and peribronchovascular interstitium (Fig 2). There were no symptoms suggestive of autoimmune diseases such as dryness, arthralgia, skin rash, or fever. The patient was followed up without treatment for the interstitial lung disease.

A 19-year-old pregnant woman at week 32 of gestation was referred to our clinic with progressive shortness of breath for the further evaluation and treatment of high-risk pregnancy. Her complaints had been existing since her childhood. ⋯ She had never smoked or drunk alcohol. Her clinical condition had deteriorated progressively with the pregnancy.
