Flashcards in Pneumoconioses Deck (21):
Eggshell calcification is pathognomonic for which condition?
Silicosis has a predominace for which lobe?
Complicated silicosis increases the susceptibility to which infectious condition?
Inhalation of coal dust not containing silica is consistent with which condition?
Coal worker's pneumoconiosis
What are the two forms of coal worker's pnumoconiosis?
1) Coal Macule = Simple CWP
- single focal accumulation (1-5mm)
- apical distribution
2) Progressive Massive Fibrosis = Complicated CWP
- conglomerate (2-3cm)
- central calcification 10%
Which type of asbestos fiber is thin and straight and penetrates deeply?
Which type of asbestos fiber is curly, flexible and smooth?
Asbestosis has a predilection for which pulmonary location?
What is the M/C pulmonary finding associated with asbestosis?
Pleural disease (eg. pleural plaques/localized pleural thickening, pleural effusion, diffuse pleural thickening)
What is the frozen mediastinum sign and which condition is it associated with?
No mediastinal shift despite presence of large effusion.
Associated with mesothelioma.
Other than mesothelioma, asbestos exposure increases the risk for which other condition and by how much?
Bronchogenic carcinoma 4x
Which pneumoconicoses condition is associated with drug abusers and how does it present?
Talcosis and presents similar to a milder form of asbestosis or complicated silicosis.
What is shaver's disease and what is it caused by?
Bauxite fibrosis --> aluminum inhalation during smelting, welding, grinding/polishing
Which pneumoconiosis can result from a single intense exposure?
berylliosis -- occurs in ceramics, nuclear weapon & fluorescent lamp
Which pneumoconiosis does not result in fibrosis as it is not fibrogenic?
siderosis (iron oxide) -- found in welders
- striking imaging features (b/c its iron)
Administering oxygen to a preeme baby with an immature lung increases the risk of developing what condition?
"Crack lung" results from intake of what substance and what are its radiographic features?
- airspace disease (pulmonary edema) and atelectasis
- may present with pneumothorax & pneumomediastinum
What is the M/C aspirated foreign body in child?
What is Mendelson syndrome?
Massive aspiration of gastric contents around time of childbirth.
Who is more susceptible to aspiration of gastric or oropharyngeal secretions?
Pregnant women or people on anesthesia, sedation, other other altered periods of consciousness.
