Giant lobar emphysema--neonatal diagnosis.

Giant emphysema of a lung lobe has distinctive features. Classically there is overdistension of the affected lung lobe, with one lobe only being involved, and, 50% of cases occur in the newborn infant [1, 4, 8]. The authors describe a particularly severe example with marked mediastinal shift and initially the hemithorax on the side of the lesion was opaque. Angiography was carried out and followed by resection when the infant was 4 months old.
