WlwG Lung (Adult) Flashcards
ILD causes: Centrilobular
RBILD or HSP
ILD causes: Perilymphatic (subpleural + peribronchovascular)
Sarcoid, Lymphangitis, Silicosis
ILD causes: Random distribution
LIP, LCH, Miliary TB
Organisms in pneumonia without volume loss
Lobar pneumonia (Strep usually, Kleb in Etoh/debilitated)
Organisms in bilateral pneumonia
Bronchopneumonia (Staph in adult, Haemophilis in child/immunocompromised)
Organisms in peri-bronchial or diffuse pneumonia
Viral (Influenza in adult, CMV in neonate/immunocompromised, Mycoplasma in autoimmune)
ILD causes: Septal thickening
Lymphangitis, Pulmonary oedema
ILD causes: Honeycombing
UIP, RA, Sarcoid
ILD causes: Smoking related
LCH (upper zone), UIP (lower zone), RBILD (bronchial wall thickening/dilation), DIP (upper and lower)
ILD causes: Bronchiolitis related - Diffuse distribution
Diffuse distribution:
Pan-bronchiolitis = Haemophilus/Pseudomonas. Diffuse centrilobular tree-in-bud nodules, mosaic attenuation with expiratory air trapping, Thickened/dilated bronchi
Lower distribution:
Follicular Bronchiolitis = RA & Sjogren. Dilated bronchi, centrilobular GGO
ILD causes: Bronchiolitis related - Lower lobe distribution
Diffuse distribution:
Pan-bronchiolitis = Haemophilus/Pseudomonas. Diffuse centrilobular tree-in-bud nodules, mosaic attenuation with expiratory air trapping, Thickened/dilated bronchi
Lower distribution:
Follicular Bronchiolitis = RA & Sjogren. Dilated bronchi, centrilobular GGO
Organism from oral infection
ActinoMycosis
AIDS organisms: GGO + cysts
Pneumocystis
AIDS organisms: Lung and CNS involvement
Cryptococcus
AIDS organisms: Lung and skin involvement
Kaposis
AIDS organisms: Lung with LN involvement
Non-hodgkin lymphoma
AIDS organisms: Lung with necrotic LN and effusion
Mycobacteria
Solitary spiculated nodule in periphery dx
AdenoCa (smoker or non-smoker) (“A thus spiculated”)
Aggressive tumour with mets, paraneoplastic syndromes
Small cell ca (“Little fighter”)
Pancoast tumour
Small cell ca (“Little fighter”)
Mass with cavitations, bilateral LN
Squamous cell ca
Cancer with septal thickening, subpleural nodules
Lymphangitis
Unresectable lung tumour T4 N3 M1 meaning?
T4 = Invasion of diaphragm/mediastinum/carina or nodules in DIFFERENT lobe. Note: Invasion of chest wall/pleura/pericardium or multiple nodules in same lobe is T3 and is resectable.
N3 = Contra-lateral LN
Mnemonic for upper ILD
“Upper body, so Large space BREAASTS usually suck them silly”
(“CDGGCDD”)
LCH = Cyst/cav
Berrylosis = noD
RBILD = Ggo (“Rebuild the DIP pool while smoking without bros or honey”)
EAA = Ggo
AS = Cyst/cav
Aspergillosis/Sarcoid/TB = noD
Silly-cosis = opacities
Upper ILD: Smoking, PTX, cavitating nodule, child
LCH (SPACES = Smoking, PTX, Apical, Cavitating nodules, Child, Eosinophilia, Skull)
LCH signs
LCH (SPACES = Smoking, PTX, Apical, Cavitating nodules, Child, Eosinophilia, Skull)
Upper ILD: Smoker, centrilobular GGO, no bronchiec/honeycombing
RBILD
Upper ILD: Centrilobular GGO, air trapping
EAA/Hypersensitivity pneumonitis
Upper ILD: Fibrobullous and emphysema
Ank Spond
Upper ILD: Central solid nodule with surrounding GGO
Aspergilosis (Halo sign, Hypersensitive/asthma/CF = ABPA, Immunocompromised = Invasive, Normal pt = Non-invasive)
Upper ILD: Subpleural/perilymphatic nodules
Sarcoid
Upper ILD: Raised serum ACE
Sarcoid
Upper ILD: Apical cavitations in poor/old/etoh/HIV, no bronchiectasis
Reactivation TB
What is Ranke complex in TB?
Calcifications from healed TB
What is Ghon complex in TB?
Regional necrotic lymph node (“ghON = NOde”)
