A 13-year-old spayed female domestic longhair cat was presented for tachypnea and was identified to have reduced lung sounds over the left hemithorax. Thoracic ultrasound examination and computed tomography identified changes consistent with bilateral lung lobe torsion. A median sternotomy confirmed torsion of both the cranial portion of the left cranial lung lobe and the right middle lung lobe. The affected lobes were resected. Pleural fluid analysis was indicative of a modified transudate and histopathology was consistent with a subacute to chronic torsion with no evidence of neoplasia or infection. The patient recovered without complication. Lung lobe torsion is an uncommon presentation across all species and is especially rare in cats. To the authors' knowledge, bilateral lung lobe torsion has not been previously reported in small animals.
一只13岁已绝育的雌性家养长毛猫因呼吸急促前来就诊，检查发现左半胸肺部呼吸音减弱。胸部超声检查和计算机断层扫描显示双侧肺叶扭转的变化。正中胸骨切开术证实左颅侧肺叶的颅部和右中肺叶均发生扭转。切除了受影响的肺叶。胸腔积液分析显示为改良漏出液，组织病理学检查结果与亚急性至慢性扭转一致，未发现肿瘤或感染迹象。患者康复，无并发症。肺叶扭转在所有物种中都不常见，在猫中尤其罕见。据作者所知，此前尚未有小动物双侧肺叶扭转的报道。
