Radiographic Changes

A mass-like, 3 cm density overlies the left hilum (arrow) on the frontal chest radiograph. On the lateral projection it is shown to be in the superior segment of the LLL (arrow), posterior to the tortuous aorta. This appearance is worrisome for lung cancer.

CT shows a 3-cm mass in the superior segment of the LLL. The mass has central low attenuation consistent with necrosis. Note the positive bronchus sign--a subsegmental bronchus leading directly to the lesion (arrow). This sign is often associated with increased diagnostic yield at bronchoscopy.
