A 58-year-old man presented with bilateral focal pulmonary opacities in the setting of asbestos-related pleural disease. CT features of the opacities were insufficiently characteristic to diagnose rounded atelectasis. Needle biopsy failed to exclude malignancy. FDG-PET imaging showed minimal metabolic activity within these opacities, allowing conservative management, as opposed to thoracotomy. Although FDG-PET findings of rounded atelectasis are known, little is known about FDG-PET results in patients with atypical rounded atelectasis on CT. FDG-PET is a useful test in the setting of asbestos-related pleural disease and rounded atelectasis, and may obviate need for more invasive and expensive diagnostic procedures.
