McCleod syndrome vs Congeital Lobar Emphysema

	Swyer-James/McCleod Syndrome	Congenital Lobar Emphysema
1	Recurrent childhood acute bronchiolitis => Obliterative bronchiolitis (adeno-virus)	Present in first 6mths, respiratory distress
2	Hyperlucent lung		Initially soft tissue density from retained fluid
3	Normal/Reduced hemithorax volume	Overexpanded lobe
4	Bronchiectasis Ventilated by collateral air-drift	Lt upper lobe > Rt middle lobe > Rt upper lobe
	HRCT: Reduced vascularity => Ipsilateral small vessel/hilum Reduced lung attenuation Air-trapping	Rx: Resection
