Multi-detector computed tomography imaging of large airway pathology: A pictorial review

Figure 26 Mounier Kuhn syndrome. Axial images (A and B) show dilated trachea-AP diameter 3.6 cm at level of aortic arch (A) with dilated bronchi (B) and diverticula formation. Bronchiectasis is seen in bilateral upper and left lower lobes with collapse of lingula (arrow in B). Coronal MinIP (C) and VRT (D) images show tracheo-bronchomegaly with diffuse diverticulosis (arrows). Virtual bronchoscopy also shows diffusely scattered defects in the walls of upper trachea (E), carina (F), right (G) and left (H) main bronchi. MinIP: Minimum intensity projection; VRT: Volume rendering technique.
