Chest radiographic and computed tomographic manifestations in allergic bronchopulmonary aspergillosis

Figure 4 High resolution computed tomography chest scan. A, B: High resolution computed tomography chest scan showing typical central bronchiectasis. The upper panel shows cylindrical bronchiectasis while the lower panel shows cystic bronchiectasis; C: High resolution computed tomography chest scan showing bronchiectasis extending to the periphery. Also seen are mosaic attenuation and centrilobular nodules; D, E: High resolution computed tomography chest scan demonstrating mucus plugging of dilated bronchi (arrows) with evidence of centrilobular nodules in a tree-in-bud fashion (arrowheads); G: High resolution computed tomography chest scan showing central bronchiectasis with extensive areas of mosaic attenuation.
