Triangular Shaped Left Upper Lobe Collapse
82-year-old female with dyspnea presents with an obstructing and infiltrating central squamous cell carcinoma of the left main stem bronchus with secondary post obstructive atelectasis of the left upper lobe of the lung. In addition, there is encasement of the left pulmonary artery and a small left effusion. A spiculated lesion at the base of the left breast in close association with the left pectoralis muscle The lesion also extends beyond the muscle to abut the rib. There is a small amount of fluid in the pericardial recess, and an small left pleural effusion.

Rectangular Shape Lingula
58-year-old female presents with a cough. CT in the axial plane shows an obstructing lesion in the left mainstem bronchus of the lung with post obstructive atelectasis of the lingula and a small portion of aerated left upper lobe anteriorly. T he major fissure is displaced anteriorly.
Pathology revealed findings consistent with a carcinoid tumor of the left bronchus.

48 year old female with a history of asthma presents with productive cough. CT scan 18 months prior confirms atelectasis in the middle lobe (upper panel and right lower panel) . There is diffuse mild multicentric foci of bronchial wall thickening in the segmental and subsegmental airways of the middle lobe, lingula and the lower lobes bilaterally (upper panel magnified in lower 3 panels).

Rounded Atelectasis
72-year-old male with a history of asbestos exposure presents with a cough. Axial CTscan shows a pleural based nodule with a comet tail and a series of lung markings folded into the nodule. There is subsegmental compensatory hyperinflation of the lateral segment of the right lower lobe Noted bilateral pleural thickening and pleural based calcification which is reminiscent of asbestos related disease. Early evolution of rounded atelectasis is also noted in the left lower lobe
