Dense hilum sign

The dense hilum sign suggests a pathological process at the hilum or in the lung anterior to posterior to the hilum. Malignancy, especially lung cancer, should be suspected.

Radiographic features

On a well-centred chest PA radiograph the density of the hilum is comparable on both sides. In the absence of calcification or adenopathy, the hila should appear of equal density and be symmetric.
