Multiple small pulmonary nodules scattered bilaterally (hard to appreciate on the thick slices), also then showing partial calcification. Bilateral apical pulmonary scars. Lungs and pleural spaces are otherwise clear. A posterior right-sided mid-tracheal diverticulum is noted, multilobulated and air-filled, with thin walls and no accumulated respiratory secretions within, measuring 4.4 x 1.7 x 3.1 cm. There is a tiny point of communication of this lesion to the trachea lumen. Airways are otherwise normal. No enlarged mediastinal lymph nodes. Hiatus hernia is noted. Calcified gallstone within the gallbladder neck is partially imaged. No suspicious bony abnormality identified.
Conclusion: Multiple small calcified pulmonary nodules are non-specific, most likely representing benign granulomatous sequela. Paratracheal air-filled cystic lesion is consistent with a tracheal diverticulum.
