Bronchiectasis due to Mycobacterial avium complex (MAC) infection. a Axial CT imaging demonstrates an upper lobe-predominant cavitary process typical of the classic form of MAC infection with associated areas of bronchial wall thickening and bronchiectasis (arrowhead). b Axial CT imaging demonstrates the nonclassical form of MAC infection, also known as Lady Windermere syndrome, characterised by mild to moderate cylindrical bronchiectasis (solid arrow) typically affecting the anterior basal right middle lobe and lingula, often with associated ill-defined tree-in-bud or centrilobular nodules (dashed arrows)
