To our knowledge, endobronchial metastases secondary to thymic carcinoma has not been reported in the literature. On high-resolution computed tomograms, the tree-in-bud centrilobular opacities caused by metastatic cells accumulating within the small bronchioles is indistinguishable from that caused by inflammatory process. Thus, in patients with thymic carcinoma and persistent tree-in-bud centrilobular opacities, endobronchial metastatic disease should be considered. © 2006 Lippincott Williams & Wilkins, Inc.
