Although neoplasm in the tracheobronchial tree are rare, a variety of tumors including primary and secondary malignant tumors as well as benign tumors are observed in routine clinical practice. On the other hand, many non-neoplastic lesions, e.g. relapsing polychondritis and infection disease, affect tracheobronchial tree and result in bronchial wall thickening and decreasing of the lumen. The diagnosis is sometimes difficult, however some neoplastic and non-neoplastic lesions of the tracheobronchial tree have specific findings. Therefore, the knowledge of radiological features of these lesions has a potential of lead to the diagnosis, and therefore the major teaching points of this exhibit are: 1. To review the imaging features of neoplastic and non-neoplastic lesions in the tracheobronchial tree at not only CT, but also MR imaging and PET or PET/CT. 2. To learn the more accurate diagnostic decision making using various modalities in routine clinical practice.

1. Imaging Features of Neoplasm in the Tracheobronchial Tree  1-1. Primary or Secondary Malignant Tumor 1-2. Benign Tumor  2. Imaging Features of Non-neoplasm in the Tracheobronchial Tree  2-1. Relapsing Polychondritis 2-2. Infectious Disorders 2-3. Others 3. Diagnostic Decision Tree of Neoplastic and Non-neoplastic Lesions in the Tracheobronchial Tree
