VASCULAR involvement in pulmonary sarcoidosis is usually limited to the small- and medium-sized vessels. However, massive hilar adenopathy may compress a major pulmonary artery and cause a large defect on the perfusion lung scan and a notable narrowing of the right upper lobe pulmonary artery as visualized by pulmonary arteriography.
This report describes a case in which the patient had mediastinal and hilar adenopathy with secondary pulmonary artery compression and corresponding reduction in perfusion seen in the lung scan. To our knowledge, only two similar cases have been previously described in the literature.1,2
