The three most important mechanisms that contribute to the pathogenesis of bronchiectasis are infection airway obstruction and peribronchial fibrosis.
Tram track x ray bronchiectasis. When found in the lungs tram tracks are radiologic signs that are usually accompanied by pulmonary edema in cases of congestive heart failure and bronchiectasis tram tracks are caused by bronchial wall thickening and can be detected on a lateral chest x ray. Imaging plays a pivotal role in the diagnosis of bronchiectasis. Tram track sign may be used in chest radiography or ct to denote the thickened non tapering parallel walls of cylindrical bronchiectasis.
Imaging of bronchiectasis bronchiectasis is defined as irreversible dilatation of a portion of the bronchial tree. Chest x rays are usually abnormal but are inadequate in the diagnosis or quantification of bronchiectasis. The term tram tracks is also used to describe the basement membrane duplication found on light microscopy.
What was seen on the chest x ray it is nothing but the tram line appearance unable to spot it. Tram track opacities are seen in cylindrical bronchiectasis and air fluid levels may be seen in cystic bronchiectasis. Parallel linear densities tram track opacities.
