Nodule
34
signs of benign solitary pulmonary nodule (SPN)
well defined nodules no associated lymph or mediastinal masses no satellite lesions calcified nodules Types of benign calcifications: dense, popcorn, lamellar

features of malignancy of SPN
spiculated nodules non-calcified nodules associated mediastinal or lymph node masses presence of cavitation large nodules

54
radiologic signs of CHF
cephalization cardiomegaly perihilar infiltrates peribronchial cuffing R. pleural effusion enlarged azygos vein kerley B lines
55
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
How do we diagnose SPN (solitary pulmonary nodule)?
1. surgical excision 2. transbronchial sampling in bronchoscopy 3. trans throracic needle aspiration 4. sputum cytology (low yield)
57
edema: laying down and all flows to dorsal region: ARDS cardiogenic edema would be nearly symmetrical and not all in the dorsal portion
58
cardiogenic pulmonary edema: edema is uniform ARDS would just be dorsal laying down
59
COPD arrows 1. increased vascular markings 2. hyperinfalated lung 3. TEAR DROP shaped heart 4. flat diaphragm
