What is a hallmark radiographic feature of asbestosis?

Patchy inﬁltrates
Eggshell calciﬁcation of hilar lymph nodes
Bilateral pleural effusion
Consolidation of the lower lobes

The correct answer is: Eggshell calciﬁcation of hilar lymph nodes

A hallmark radiographic feature of asbestosis is eggshell calciﬁcation of hilar lymph nodes. This means that the lymph nodes near the center of the chest have a characteristic appearance on an X-ray due to the presence of calcium deposits. This is a specific finding and can help differentiate asbestosis from other lung conditions. The other options listed do not have a strong association with asbestosis. Patchy infiltrates and consolidation of the lower lobes can be seen in various lung diseases, while bilateral pleural effusion is more commonly seen in heart or liver disease.
