( Adenocarcinoma)

Question 13

Most common lung cancer caused in Asbestosis

Answer 13

Bronchogenic Cancer

Question 14

Diagnosis of Silicosis

Answer 14

ACUTE :
Hilar LNAP
BAL- milky fluid , PAS + flocculent densities
HRCT - Crazy pavement appearance
Ground glass opacities with interstitial septal thickening along with interspersed normal areas

CHRONIC :
CXR- Egg shell calcification in upper lung (<1cm nodules )
- conglomerate masses

Question 15

Cause of productive cough in acute silico proteinosis

Answer 15

Secondary alveolar proteinosis
Due to collection of Surfactants as a result decreased macrophage action ( because of exposure to silica dust )

Question 16

Silica reaction

Answer 16

Formation of calcified fibrotic nodule in lung parenchyma which causes inflammatory reaction leading to PMF in later stages

Question 17

Silicosis increases risk of

Answer 17

TB
COPD
LUNG CANCER
COR PULMONALE
CAPLANS SYNDROME

Question 18

Erasmus syndrome

Answer 18

Systemic sclerosis after exposure to SILICA

Question 19

Comet tail sign

Answer 19

HRCT finding
Seen in Rounded atelectasis / folded lung syndrome / Blesovsky syndrome

Diffuse pleural thickening pulls bronchoalveolar bundles thus producing sign

Rare complication of Asbestosis

Intense pleural reaction causing folding of lung and pleura
