Ultrasound aspect of a lung consolidation and a pleural effusion. (a) Transversal view of consolidated left lower lobe; lung consolidation is seen as a tissular structure (C).

(b) Cephalocaudal view of consolidated left lower lobe: lung consolidation with air bronchograms. Ao, descending aorta; D, diaphragm; Pl, pleural effusion.
