Extralobar

More common (75-85% cases)
Less common (15-25% cases)
 Presentation
Usually Child with recurrent infections
Usually Neonate with respiratory distress and cyanosis
Arterial supply
Aorta (Same in both types)
Venous supply
usually Pulmonary venous  drainage
Usually systemic venous drainage

Same pleura as ipsilateral lung
Separate pleura from ipsilateral lung

60% cases affect left lower lobe (Most commonly Posterior basal segment); 40% right lower lobe.
