Congenital lobar emphysema in two dogs

Abstract

ABSTRACT Congenital lobar emphysema is described in two dogs. The condition was characterized by progressive dyspnoea and cyanosis from a very young age. There was marked expiratory effort, and wheezing and crackling were evident on auscultation. Radiographic examination revealed overdistension and emphysema of the right middle lobe with displacement of the heart and mediastinum to the opposite side. The pathology and possible treatments are discussed.
