Flashcards in Chest Radiology Deck (38):
1

Indications for CXR

1. Dyspnea, Cough, Hemoptysis 2. Chest pain 3. Fever 4. Weight loss 5. Suspected pulmonary or CV involvement from systemic disease 6. Monitoring of previously defined Pulmn or CV abn 7. ‘Routine’

2

ABC CXR Mnemonic

A – Address B – Bony Cage C – Cardiac silhouette D – Diaphragm E –ETT, Esophagus, Lines etc F – Fields of the lung G – General impression

3

Four basic densities in XR

bone fat soft tissue air

4

(PA/AP) is for normal, healthy patients who can stand.

PA

5

What is the lantern effect?

due to the AP view of the XR, the heart appears larger (hand in front of a flashlight)

6

What lobe does not extend posteriorly? What lobe does not extend anteriorly?

RML RLL

7

Which lobe has the lingula?

LLL

8

Airspace disease shows up as...

acinar shadows, which appear as "cotton ball" patterns or dots

9

Interstitial disease shows up as...

lines or reticulations; web-like

10

Air bronchograms occur classically in what condition?

pneumonia

11

What condition? CXR shows cardiomedaly with perihilar infiltrate

CHF

12

2 abnormalities seen on this CXR

Cardiomegaly

perihilar infiltrate

13

What is this abnormality called? What's the related condition?

bat wing infiltrate

pulmonary edema

14

Radiologic signs of CHF

1. Cephalization
2. Cardiomegaly
3. Perihilar infiltrates
4. Peribronchial cuffing
5. R. Pleural effusion
6. Enlarged Azygos vein
7. Kerley B lines (lymphatics containing excess fluid)

15

Earliest radiologic sign of CHF?

cephalization

16

What's wrong with this guy?

cardiomegaly

17

What is cephalization?

LV dysfunction causes increased pressure in pulmonary veins; upper lobe vasculature is more prominet and blood flows cephalic instead of caudal

18

How is the CXR on the R abn?

cephalization

19

What is abn?

Fluid in the fissures

20

5 air space diseases, and what substance you see in CXR:

  • Pulmonary edema – fluid
  • Pneumonia - Exudate, or WBCs
  • Pulmonary hemorrhage – blood
  • Tumor/ Broncho alveolar cell carcinoma
  • Idiopathic – e.g., Pulmn Alveolar proteinosis

21

What do you see on CXR in a patient with sarcoidosis?

interstitial lung disease with reticulonodular infiltrates

bilateral hilar adenopathy

22

What conditionas cause bilateral hilar and mediastinal lymphadenopathy?

  • Lymphoma
  • Histoplasmosis
  • Phenytoin use
  • Tuberculosis
  • HIV
  • Sarcoidosis
  • (Castleman's Disease)

23

What does honeycomb pattern indicate?

advanced stage interstitial dz

24

What are 2 conditions that will show a honeycomb pattern?

IPF

rheumatoid lung

25

What is abnormal about CXR in COPD?

flattened hemidiaphragm

increased lung markings 

hyperinflation

narrow vertical heart (if no CHF)

(*also, bullous disease possible)

26

What is this condition?

COPD

(you shouldn't see ribs 11 and 12!)

27

1. asc aorta

2. SVC

3. PA (pulm artery?)

4. D. Aorta

5. carina

28

What is bronchiectasis?

persistent dilation of terminal bronchi

29

What is the most common CXR pattern for a patient with a pulmonary embolus?

most common = normal

(but pleural effusions may be present when PE is small; atelectasis may be present)

30

Possible CXR associated with pulm embolus:

elevated L hemi diaphragm

hampton's hump

westermark sign (no vasc markings, not pneumo)

 

31

What % of solitary pulm nodules are malignant?

30-40%

32

Features of benignity in solitary pulm nodules

  • Well defined nodules
  • No associated lymph node or mediastinal masses
  • No satellite lesions
  • Calcified nodules

33

Types of Benign calcifications

Dense
Popcorn
Lamellar

34

Features of Malignancy in solitary pulm nodules

Spiculated nodules
Non-calcified nodules
Associated mediastinal or Lymph node masses
Presence of Cavitation
Large nodules
