A seven-month-old, entire, male miniature schnauzer dog was referred with acute vomiting, inappetence and depression primarily as a result of a gastric foreign body (pine cones). During investigations, thoracic radiographs revealed increased volume of the right lung lobes, deviated cardiomediastinal structures and elevation of the heart from the sternum. Thoracic computed tomography revealed left cranial lung lobe hypoplasia and extension of the right cranial lung parenchyma across the midline to the left hemithorax. Branches of the right pulmonary vessels and bronchi also crossed the midline and extended to the left caudal lung lobe. These findings suggested that the right and left lungs were fused. In humans this finding is consistent with horseshoe lung, which is an uncommon congenital malformation. To the authors' knowledge, this case represents the first report of such a pulmonary anomaly in a dog.
一只七个月大、未绝育的雄性迷你雪纳瑞犬因胃内异物（松果）导致急性呕吐、食欲不振和精神沉郁前来就诊。在检查过程中，胸部X光片显示右肺叶体积增大、心脏纵隔结构偏移以及心脏远离胸骨抬高。胸部计算机断层扫描显示左颅肺叶发育不全，右颅肺实质越过中线延伸至左半胸。右肺血管和支气管分支也越过中线并延伸至左尾肺叶。这些发现提示左右肺融合。在人类中，这一发现与马蹄肺相符，马蹄肺是一种罕见的先天性畸形。据作者所知，该病例是犬类中这种肺部异常的首例报告。
