34
Q

signs of benign solitary pulmonary nodule (SPN)

A

well defined nodules

no associated lymph or mediastinal masses

no satellite lesions

calcified nodules

Types of benign calcifications: dense, popcorn, lamellar

35
Q

features of malignancy of SPN

A

spiculated nodules

non-calcified nodules

associated mediastinal or lymph node masses

presence of cavitation

large nodules

38

52
Q

How does acinar/alveolar/airspace disease appear on xray?

53
Q

How does interstitial disaese appear on xray?

A

lines in irregular weblike pattern

54
Q

radiologic signs of CHF

A

cephalization

cardiomegaly

perihilar infiltrates

peribronchial cuffing

R. pleural effusion

enlarged azygos vein

kerley B lines

55
Q
A
  1. Ascending aorta
  2. left pulmonary artery
  3. left mainstem bronchus
  4. Descending aorta
  5. esophagus
  6. right mainstem bronchus
  7. superior vena cava
56
Q

How do we diagnose SPN (solitary pulmonary nodule)?

A
  1. surgical excision
  2. transbronchial sampling in bronchoscopy
  3. trans throracic needle aspiration
  4. sputum cytology (low yield)
57
Q
A

edema: laying down and all flows to dorsal region: ARDS

cardiogenic edema would be nearly symmetrical and not all in the dorsal portion

58
Q
A

cardiogenic pulmonary edema: edema is uniform

ARDS would just be dorsal laying down

59
Q
A

COPD

arrows

  1. increased vascular markings
  2. hyperinfalated lung
  3. TEAR DROP shaped heart
  4. flat diaphragm
