adenocarcinoma arising from the right upper lobe bronchus (a) Posteroanterior radiograph shows a large opacity with a sharp lateral margin Since the trachea is slightly displaced to the left, a mediastinal mass may be considered Note elevation of the right hemidiaphragm (b) CT demonstrates the atelectatic right upper lobe adjacent to the mediastinum The right main bronchus is stenotic due to tumour invasion • Mar 31, 2016 39 • Figure 61-year-old woman with combined right middle and lower lobe atelectasis due to bronchial tuberculosis (a) Posteroanterior radiograph shows a mass-like opacity with a sharp margin lateral to the right cardiac border (arrow) The right hilum is small and inferiorly displaced (b) CT clearly demonstrates marked atelectasis of the right middle lobe (arrow) and right lower lobe (arrowhead) with dilated bronchi containing mucus • Mar 31, 2016 40 • Figure 40-year-old woman with combined right middle and lower lobe atelectasis due to bronchial tuberculosis (a) Posteroanterior radiograph shows a mass-like opacity with a convex lateral margin A thymoma was suspected as the patient had been suffering from myasthenia gravis (b) CT clearly demonstrates atelectatic right middle lobe (arrow) and right lower lobe (arrowhead) with dilated bronchi containing mucus Bronchial tuberculosis was confirmed at right middle and lower lobe • Mar 31,

lateral margin overlying the right hilum (b) Anterior location and sharp outer margin of the atelectatic lobe are demonstrated on the lateral radiograph (c) Note that the atelectatic lobe migrates with change in the patient's position, as seen on CT scout view (d) The atelectatic right upper lobe is located posteriorly on axial CT in the supine position (Courtesy of Yasuyuki Kurihara, MD, St

with right upper lobe atelectasis associated with localized pneumothorax The patient had congenital hypertrophic cardiomyopathy Anteroposterior radiograph shows a localized pneumothorax adjacent to the atelectatic right upper lobe, "pneumothorax ex vacuo" Note that the pneumothorax is bounded by the outline of the atelectatic upper lobe (arrowheads) • Mar 31, 2016 46 Mar 31, 2016 47 Mar 31, 2016
