Revise Radiology Resp Flashcards
Geographic ground glass with smooth interlobular septal thickening
PAP (Crazy paving)
NF1 lung findings
Lower zone fibrosis,
Thin walled bullae in upper zones
Acute interstitial pneumonia
Bilateral ground glass opacities and consolidation lower lobe predominence, sparing costophrenic angles.
Late phase: traction bronchiectasis and honeycombing
Cryptogenic organising pneumonia
Patchy consolitation and ground glass, peripheral and peribronchial distribution
Langerhand cell histiocytosis

Increased inflammatory changes and lymph nodes
Sarcoid
Bilateral perilymphatic nodules, mediastinal and hilar lymphadenopathy
Kaposi sarcoma
Multiple perilymphatic and peribronchovascular nodules
Desquamative interstitial pneumonia

LCH vs LAM
LCH shows nodules in addition to cysts, predominantly upper and mid zones
LAM shows thin walled cysts only, diffusely spread
