Week 4 Radiology CXR 2

Categorize the Characteristics.

Groups:

(a) Air Space

,

(b) Interstitial

,

(c) Both

• "Bat wing" pattern

• Air Bronchograms

• Lung cancer

• Bilateral

• Lung stiffness, scarring results

• No Lobar margins

• ARDS

• Pulmonary Alveolar Edema

• Fluffy, hazy infiltrates

• Aspiration pneumonia

• Silhouette Sign

• No air bronchograms

• Honeycombing

• Masses, dots, lines, thickening

• Infections, Autoimmune, fibrotic dx

• Tuberculosis

Answer explanation

Pneumocystis jirovecii is another example of Air space disease

Where does Reactivation TB like to live?

• Cerebral cortex

• Lower Lobes

• Right Atrium

• Upper lobes/apices

Common causes of interstitial disease...

• Cancer

• Atypical Pneumonias

• Pulmonary Fibrosis

• RA

• Asbestosis

Answer explanation

Silicosis, coal workers lung, TB, Sarcoidosis also on the list.

Which form of TB is classified as interstitial?

• Miliary TB
• Extrapulmonary TB
• Pulmonary TB
• Latent TB
• Cavitary TB

In CHF, you can find what characteristics on CXR?

• Cardiomegaly, cephalization, pleural effusions, Kerley B lines

• Pneumothorax, atelectasis, bronchiectasis
• Pulmonary fibrosis, emphysema, lung nodules
• Ascites, hepatomegaly, splenomegaly
• "plump" pulmonary casculature, fluid in fissurs, Fluffy/hazy air space

LATE CHF sign = ​ (a)   . EARLY CHF sign = Interstitial edema with ​ (b)  

• Pleural effusion
• Cardiomegaly
• Pulmonary edema
• Alveolar edema
• Engorged pulmonary vessels

What is a very common finding after surgery, major infection, or scarring? ​ (a)  

• Atelectasis
• Pneumothorax
• Hemoptysis
• Latent TB
• CHF

What is the Golden S sign in radiology?

• Backwards S that typically indicates cancer on a chest X-ray

• Indication of a pleural effusion on a chest X-ray
• Appearance of a normal appendix on an abdominal X-ray
• Finding of a pneumoperitoneum on an abdominal X-ray

Organize these options into the right categories

Groups:

(a) Atelectasis

,

(b) Pneumonia

• Air space disease

• Linear, wedge shaped opacification

• No apex

• Normal or increased volume

• No shift

• Ipsilateral shift of the mediastinal stuctures

• Volume Loss

• In lobar collapse, apex is at the hilum

Atelectasis ​ ​ (a)   to the opacified side, while a Pleural Effusion ​ ​ (b)   from the opacified side.

• contracts
• inflates
• shrinks
• compresses
• shift away
• shift toward

Answer explanation

Pneumonectomy also shifts toward the opacified side.
