Asbestosis causes all of the following EXCEPT:
Asbestosis causes all of the following EXCEPT:
Show Hint
Asbestosis is a basal interstitial fibrosis; enlarged hilar nodes point instead to sarcoidosis or silicosis.
Updated On: Jun 24, 2026
- Shaggy heart borders
- Honeycombing
- Hilar lymphadenopathy
- Basal peribronchial fibrosis
Show Solution
The Correct Option is C
Solution and Explanation
Step 1: In asbestosis, inhaled asbestos fibres lodge in the lower zones and drive progressive interstitial fibrosis predominantly at the lung bases.
Step 2: Radiologically this basal-predominant fibrosis produces peribronchial fibrosis at the bases, end-stage honeycombing, and irregular, ill-defined cardiac and diaphragmatic margins described as the shaggy heart sign. All three of these are genuine features.
Step 3: Enlargement of the hilar lymph nodes is not part of the asbestosis picture; it points instead to sarcoidosis or silicosis. So among the options, hilar lymphadenopathy is the odd one out.
Step 4: The exception is therefore hilar lymphadenopathy.
\[\boxed{\text{Hilar lymphadenopathy}}\]
