PURPOSE: @entity2783 includes a spectrum of diseases associated with an abnormal extracellular deposition of amyloid. The respiratory system is involved in approximately 50% of @entity1 with @entity2783 . The purpose of this review is to present the CT findings of @entity17220 . METHODS: We reviewed the CT findings of @entity17220 from the previous reports and our experiences. RESULTS: Three patterns of involvement in respiratory system are presented: tracheobronchial nodular and diffuse parenchymal. CT demonstrates nodules, plaques, or diffuse thickening of the airways with @entity730 . @entity891 is associated in case of diffuse airway involvement. Parenchymal nodules have sharp and lobulated margins with peripheral or subpleural locations. High-resolution CT shows @entity231 , interlobular septal thickening, and small, well-defined nodules of 2 to 4-mm in diameter predominantly in the subpleural regions. CONCLUSION: @entity17220 has variable findings and CT scans clearly depict extent and distribution of the disease, its postobstructive @entity358 , and other associated findings such as @entity730 and lymphadenopathy.
