Focal and Multifocal Lung Diseases Flashcards
If multiple pulmonary nodules are seen on imaging, the etiology is suspected to be this type of cancer
Hematogenous spread from elsewhere in the body (metastasis)
This multifocal pulmonary infiltrate looks like pneumonia but has more hemoptysis and is common in immunosuppressed patients
Invasive aspergillosis
Which cavitary pulmonary infiltrate shows with effusions and air-fluid levels in the cavities?
Pyogenic bacterial pneumonia
Tests for cavitary GPA (Wegener granulomatosis)
cANCA/PR3 or pANCA/MPO
Will also have elevated ESR
Biopsy preferred (renal better than lung)
Describe the cough in segmental/lobar tuberculosis
Non-productive
May have hemoptysis
Which eosinophilic pneumonia will present without peripheral eosinophilia?
Acute eosinophilic pneumonia (too fast to spread)
A ball seen on the peripheral edge of the lung with a comet tail would be seen in this condition
Rounded atelectasis
Are foreign bodies causing segmental/lobar pulmonary blockage more often radiolucent or radiopaque?
90% are radiolucent (don’t show up)
This fungus can cause lung masses up to 10cm in size
Cryptococcus
Tuberculosis infiltrates typically show on chest x-ray with this appearance and in this area of the lungs
Cavitations
In upper lung zones
Size of pulmonary nodules
<3mm (larger is a mass)
True or false. Bacterial pneumonia commonly presents as segmental/lobar infiltrates
False. More commonly focal/multifocal
Wedge shaped infiltrates on chest x-ray (Hampton Hump) suggest this condition
Pulmonary infarction
True or false. A single nodule in the lung is rarely a metastatic malignancy
True
Metastatic carcinomas in the lungs have this classic appearance on imaging
Cannon-ball metastases in lower lobes
This type of eosinophilic pneumonia will present with rales
Acute eosinophilic pneumonia
Most common cause of rapidly growing lung cancers which present with cavitations
Squamous cell carcinoma
(cancer outgrows its blood supply)
Three most common cancers that cause pulmonary metastatic carcinomas
Renal
Prostate
Breast
Describe bronchopulmonary sequestration and how it would look on imaging
Lung area that never developed properly
Well-defined on imaging with no change over time
Treatment for BOOP
Chronic prednisone
In which airways are carcinoid tumors typically found?
Central airways
Radiation pneumonitis typically shows up this long after exposure
1-6 months after radiation
Describe the process that commonly leads to lung lobe torsion
Lungs are moved aside during CABG surgery
Torsion obstructs blood flow
Post-op, patient gets perfusion-reperfusion injury
Aspiration of medications with this ingredient in particular is a medical emergency
Medications containing iron
