Q

Predominantly reticular interstitial lung disease?

Study These Flashcards

A

Pulmonary interstitial edema
Idiopathic pulmonary fibrosis
Rheumatoid lung

Predominantly nodular interstitial lung disease?

Brochogenic carcinoma | Mets of the lungs

Mixed reticulonodular interstitial lung diseases?

Sarcoidosis

Characteristics of interstitial lung disease?

Has discrete reticular, nodular, reticulonodular opacities Packets of disease are separated by normal appearing lung Margins of packets are sharp and delineated Usually no airbronchograms are present

Pulmonary interstitial edema is the precursor of what?

Alveolar edema

Pulmonary interstitial edema manifest 4 key radiologic signs?

Fluid in the fissures (major and minor) Peribronchial cuffing (fluid in the walls of the bronchioles) Pleural effusions and Kerley B lines

Four major cell types of bronchogenic carcinoma

Adenocarcinoma Squamous cell carcinoma Small cell carcinoma Large cell cercinoma

Adenocarcinoma can present as a solitary peripheral pulmonary nodule

True

Mets to the lung can be divided into three categories depending on the pattern of disease demonstrated in the lung...?
