Congenital Bronchial Hypoplasia in Calves
1966
Thomson, R. G.
The literature on anomalies of the lung in domestic animals was reviewed. Three cases of congenitally anomalous lungs in calves were described. Two were cases of accessory lungs, and one was a case of hypoplasia of the bronchi affecting both normally situated lungs of a calf. Hypoplastic bronchi were also present in the two cases of accessory lungs. The pathogenesis of these anomalies was discussed in the light of what is known of the embryology of the porcine lung. The basic defect was considered in all three cases to be hypoplasia of the bronchi, which can occur either in conjunction with acessory lungs or otherwise.
