Witwer - Pulmonary Disease/Chest Films Flashcards
lobes of the right lung
upper
middle
lower
fissures of the right lung
major
minor
lobes of the left lung
upper
lower
fissure of the left lung
major/oblique
the lung appears __ on CXR
bc it is filled w. __
dark
air
the heart appears __ on CXR
bc it is __ density
gray
water
what causes the silhouette sign
fluid, pus, or blood (fluid density) fills the lung → water density next to water density → obliterates boundary btw lung and heart
silhouette sign is commonly seen w. (2)
PNA
atelectasis
what structure in the lung forms a lace-like network that supports the lung
interstitium (same same stroma)
interstitium/stroma includes (3)
area btw alveolar epithelium
capillary endothelial basement membrane
perivascular and perilymphatic tissue
area of the lung involved in gas exchange
parenchyma
parenchyma includes (2)
alveoli
capillaries
fibrosis is a type of __ lung dz
interstitial
types of interstitial densities
coarse
strandy
linear
reticular
nodular
honeycomb
reticulonodular
pus, blood, fluid, or tumor in parenchymal airspaces
alveolar infiltrates
alveolar infiltrates are typically caused by what dz process
PNA
describe alveolar densities (5)
confluent
coalescent
hazy
fluffy
ill-defined
6 disease processes commonly associated w. alveolar infiltrates
PNA
COVID
CHF
atelectasis
PE
neoplasia
dense alveolar infiltrate in the lung w.o air bronchogram
drowned lung → bronchus filled w. fluid
air bronchograms are seen with
alveolar disease
fluid, pus, blood, fibrosis, or tumor in the interstitum/stroma, bronchi, pulmonary arteries, veins, or lymphatics
interstitial infiltrates
describe interstitial infiltrates
reticular
fine
coarse
strandy
linear
nodular
reticulonodular
honeycomb
7 dz processes that cause interstitial infiltrates
emphysema
bronchiectasis
asthma
kerley’s lines
sarcoidosis
CF
TB
wall of bronchi become thickened bc of fluid, inflammation, chronic infxn, bronchiolitis, CF
bronchial cuffing
bronchial cuffing is same-same
donut sign
bronchial cuffing dt CHF involves
fluid
bronchial cuffing dt PNA involves
infxn
what does bronchial cuffing due to inflammation make you think of
asthma
bronchial cuffing dt chronic inflammation commonly involves (2)
bronchiectasis
CF
network of crossing lines on CXR - linear interstitial pattern
kerley’s lines
what do you think when you see kerley’s lines
pulmonary edema → CHF
