Multiple circular or oval pulmonary densities on chest roentgenogram most commonly represent neoplastic metastases. This radiographic picture may also be seen in other tumors (lymphoma, myeloma), infectious diseases (especially tuberculosis and fungal chest diseases), immunologic disorders (Wegener’s granulomatosis and rheumatoid lung), mucoid impaction, pneumoconiosis, A-V fistulae, multiple bronchial adenomas, benign metastasizing leiomyomas, hydatid cysts, pulmonary infarcts, laryngeal-tracheal-bronchial papillomatosis, hamartomas, multiple hematomas, splenosis, extramedullary hematopoiesis and nonspecific lung impaction abscesses. Sarcoidosis rarely produced multiple pulmonary nodules. The purpose of this report is to describe six cases of biopsy-proved sarcoidosis with this uncommon radiologic manifestation. These cases represent an incidence of 4.0 percent in a series comprising 150 patients.
