abnormal chest Flashcards
consolidation
infiltrate or solid engorgement
congestive heart failure
hilar engorgement and increase heart size
pneumothorax
air in the pleural cavity
atelectasis
collapse of the lung due to obstruction
alveolar
air sacs
interstitial
spaces within a lung or tissue/spaces between alveoli
pleural effusion
fluid in the pleural cavity
patterns of disease
- diffuse
- focal
- lung volume
- pleural disease
- lymphadenopathy
two divisions of diffuse disease pattern
airspace disease and interstitial opacity
two divisions of focal disease patterns
nodules/masses
blebs/bullae/cysts/cavities
what will airspace disease look like
is it focal or diffuse
a confluent fluffy or hazy opacity resulting from fluid density in the alveoli
it is diffuse and can involve part or the whole lung
what is air bronchogram sign
what is it indicative of
indication of airspace disease
an air filled bronchus surrounded by an airless lung
if air bronchogram sign is present where is the lesion causing the issue
in the lung
describe what the airspace disease will look like on xray
hazy, fluffy, confluent opacities with indistinct margins and airbronchogram or silhouette sign
what is the acute DDx for air space opacity
- pneumonia
- pulmonary alveolar edema
- hemorrhage
- aspiration
- near-drowning
what is the DDx for chronic air space opacity
- bronchoalveolar cell carcinoma
- alveolar cell proteinosis
- sarcoidosis
- lymphoma
interstitial lung disease
development of particles in the interstitium
interstitium
connective tissue, lymphatics, blood vessels, and bronchi that surround and support airspaces
three characteristics of interstitial lung disease
- reticular, nodular, or reticulonodular pattern
- packets of disease surrounded by normal lung
- can be focal of diffuse
define the reticular/nodular pattern found in interstitual lung disease
small, well defined white nodules and lines that cna be fine, thin, lacy densities
description of interstitial opacities based on pattern
- reticular (too many lines)
- nodular (too many dots)
- reticulonodular (too many lines and dots)
DDx for interstitial opacities
- idiopathic interstitial pnemonia
- infection
- pulmonary edema from CHF
- idiopathic pulmonary fibrosis
- environmental factors
- hemorrhage
- sarcoidosis
- tumor/metastases
in what disease would a miliary pattern appear on xray
tuberculosis
distinguish between a nodule and mass
nodule is any pulmonary radiographic lesion that is sharply defined, discrete, nearly circular, and less that 3cm
a mass is larger than 3cm
