Media file 6: Asthma. High-resolution CT scan of the thorax obtained during expiration in a patient with recurrent left lower lobe pneumonia shows a bronchial mucoepidermoid carcinoma (same patient as in Image 5 in Multimedia). Note the normal increase in right lung attenuation during expiration (right arrow). The left lung remains lucent, especially the upper lobe, secondary to bronchial obstruction with airtrapping (left upper arrow). The vasculature on the left is diminutive, secondary to reflex vasoconstriction. Left pleural thickening and abnormal linear opacities are noted in the left lower lobe; these are the result of prior episodes of postobstructive pneumonia (left lower arrow).
