A 60-year-old man with colloid adenocarcinoma. Coronal (a) and axial (b) chest computed tomography images showed irregular subpleural nodules and plaques accompanied by air bronchograms that involved the lower lobe of the right lung. Positron emission tomography/computed tomography showed there was slightly increased radioactivity uptake, with maximum standardized uptake value of 3.5 (c). A soft tissue density lesion was found in the left adrenal gland (d) with increased radioactivity uptake and maximum standardized uptake value of 4.1 (e). On histological examination, the tumor was composed predominantly of pools of mucin; hematoxylin and eosin stain, ×400 (f)
