Conglomerate masses

large nodular or mass-like opacities, in patients with diseases characterized by small nodules. They are common in sarcoidosis, silicosis and coal workers pneumoconiosis. Large masses of fibrous tissue may also surround and encompass bronchi and vessels within the central or parahilar lung in patients with progressive fibrotic lung disease, resulting in conglomerate masses. Bronchi within these masses may be crowded together and are usually dilated as a result of fibrosis and traction bronchiectasis (see progressive massive fibrosis).
