Abstract：
A 2-year-old castrated Russian Blue cat presented with inappetence, depression, and labored respirations. Radiography findings suggested left lung atelectasis; however, the ultrasonography findings did not indicate lung atelectasis. The left pulmonary artery (PA) was abnormally small on echocardiography; further, there were no other cardiac anomalies. Computed tomography revealed an abnormally small left PA and left lung. Furthermore, bronchiectasis and tree-in-bud patterns were observed in the lung lobes. Based on these findings, the cat was diagnosed with isolated left PA hypoplasia, presumed left lung hypoplasia, and feline chronic bronchial disease. Early diagnosis of this disease is important because it can cause serious complications, including recurrent respiratory infection, bronchiectasis, massive hemoptysis, and pulmonary hypertension.
摘要：
一只2岁被阉割的俄罗斯蓝猫食欲不振，抑郁症,和费力的呼吸。X线检查结果提示左肺不张；然而，超声检查结果未提示肺不张.左肺动脉（PA）在超声心动图上异常小；进一步，没有其他心脏异常.计算机断层扫描显示左PA和左肺异常小。此外，在肺叶中观察到支气管扩张和芽中树的模式。基于这些发现,这只猫被诊断出患有孤立的左PA发育不全，推测左肺发育不全,和猫慢性支气管疾病。这种疾病的早期诊断很重要，因为它会导致严重的并发症，包括反复呼吸道感染,支气管扩张,大咯血,和肺动脉高压。
