Abstract

A rounded density is occasionally seen hanging down from the hilus in the presence of a large pneumothorax. To find an explanation for this appearance, the authors obtained a right-sided bronchogram on a baboon, after which they induced pneumothorax on the same side. This experiment demonstrated that the rounded density is formed by a twisted and atelectatic upper lobe.
