Parenchymal Restrictive Lung Disorders

Question 1

Chronic inflammation of alveolar walls–>diffuse progressive fibrosis & destruction of normal architecure of lung

Risk factors: amiodarone, et al.

Progressive dypsnea/constitutional symptoms/fine, basilar inspiratory crackles

Bilateral reticulonodular opacities in basilar lungs

Corticosteroids may provide symptomatic relief, nintednaib, pifrenidone, transplant

Answer 1

Pulmonary fibrosis

Question 2

Mulitsystem, inflammatory disease–>noncaseating pulmonary and lymph node granulomas

Dry cough, dyspnea & erythema nodosa/most common in black, middled aged females

Bilateral hilar adenopathy

Sponatneously resolves

Answer 2

Sarcoidosis

Question 3

Diffuse small opacities (especially in upper lungs)

Often asymptomatic

Occupational harzard

Answer 3

Coal worker’s lung

Question 4

Nodular interstitial fibrosis

Progressive dyspnea/inspiratory crackles

**Linear streaking at lung base/opacities and pleural calcifications **

No specfici tx

Answer 4

Abestosis

Question 5

Inflammatory pulmonary disease with instigating factors ranging from bird poo to moldy molasses

S/S: Malaise/chills/fever/cough/dypsnea/bibasilar crackles

Dx: Small nodular densities sparing apices and bases

Tx: Predniose

Answer 5

Hypersensitivity Pneumonitis

Question 6

Asthma like disorder related to exposure to dust generated from vegetable fibers and cotton textiles

Chest tightness/cough/dypsnea worse when returning to work after a peroid off
