Abstract

Pulmonary malformations are rare equine congenital anomalies. Over a three-year timeframe, three cases of left sided pulmonary agenesis were diagnosed in perinatal foals. All three cases were associated with concurrent ipsilateral diaphragmatic herniation and hypoplasia of the right lung lobe. All three foals died immediately following parturition due to perinatal asphyxia associated with the congenital malformations. To the author’s knowledge, this is the first report of pulmonary agenesis in the horse.
