Pulmonary Sarcoidosis Presenting with Miliary Opacities.

Lung lesions often appear in patients with sarcoidosis; however, miliary opacities are rare. We herein report the case of a 40-year-old woman with pulmonary sarcoidosis who presented with dyspnea on exertion. Subsequent computed tomography showed miliary opacities, and the presence of granulomas was confirmed by a transbronchial lung biopsy. Glucocorticoid therapy was initiated and the symptoms and miliary opacities rapidly improved. Although miliary sarcoidosis is uncommon, physicians should consider sarcoidosis in addition to tuberculosis, malignancy, and pneumoconiosis when presented with miliary opacities.
