Lung architectural distortion in thoracic radiology refers to a descriptive term give when the normal pulmonary bronchial, vascular, fissural or septal anatomy is disrupted and manifested as loss of smooth course of the fissures, crowding of dilated bronchioles or vessels with angulated course 1. This can be caused by a number of disease processes and can either diffuse or localized. Any form of pulmonary fibrosis can particularly result in lung architectural distortion.
Other features that can accompany lung architectural distortion include:
