Perihilar peribronchial thickening affects the region near the hilum where bronchi blood vessels and lymph nodes are located. It is often associated with infections lymph node enlargement or diseases like sarcoidosis.

 

Many disease processes involve the hila so a knowledge of their normal X-ray appearance is important. Both hila should be of similar size and density. If either hilum is bigger and more dense (whiter) than normal this may indicate an abnormality.

 

The perihilar region is significant on chest radiography because it contains the pulmonary arteries bronchi lymphatics and central lung interstitium?structures whose abnormalities can indicate serious pathology including lung cancer pulmonary hypertension lymphadenopathy and infectious diseases. 1 2

 

The term mosaic attenuation describes density differences between affected and unaffected lung regions resulting in a patchy appearance of black and white lung areas.

 

The hilum is a region in the lungs where airways blood vessels and nerves enter and exit. Enlarged hilar lymph nodes can be caused by infections like tuberculosis or conditions like cancer.

 

Finally the area surrounding the hilum of the lung is called the perihilar region. Quiz yourself on the structures found at the hilum of the lung or take a look at our study unit: Hilar abnormalities can present both unilaterally and bilaterally.
