We described the diagnosis and successful treatment of pleural and peritoneal effusion secondary to liver lobe torsion in a dog. A 12-year-old female spayed Borzoi dog was referred for heart failure. Emergency room thoracic and abdominal ultrasound showed a large volume of pleural effusion with mild peritoneal effusion and an abdominal mass. Pleural fluid analysis classified the effusion as exudative. A complete ultrasound revealed mild peritoneal effusion and decreased blood flow to the right liver lobe. Other causes of bicavitary effusion were ruled out based on blood work, ultrasound, echocardiogram, and computed tomography. The patient was taken to surgery and diagnosed with caudate liver lobe torsion and had a liver lobectomy. At the 2-week postoperative recheck, the patient was doing well and there was complete resolution of the pleural effusion. Liver lobe torsion is a rare occurrence in dogs and can be difficult to diagnose. Clinical signs are nonspecific for liver lobe torsion and patients may present in respiratory distress with significant pleural fluid accumulation. When assessing patients with pleural and peritoneal effusion, liver lobe torsion should be considered as a differential diagnosis.
我们描述了一只狗因肝叶扭转继发胸腔和腹腔积液的诊断及成功治疗过程。一只12岁已绝育的雌性波索尔犬因心力衰竭前来就诊。急诊室的胸部和腹部超声检查显示大量胸腔积液伴轻度腹腔积液及一个腹部肿块。胸腔积液分析将该积液分类为渗出液。全面的超声检查显示轻度腹腔积液且右肝叶血流减少。基于血液检查、超声、超声心动图和计算机断层扫描排除了双腔积液的其他病因。该患者接受了手术，被诊断为肝尾叶扭转并进行了肝叶切除术。术后2周复查时，患者情况良好，胸腔积液完全消退。肝叶扭转在犬类中很少见，且可能难以诊断。肝叶扭转的临床症状不具有特异性，患者可能因大量胸腔积液积聚而出现呼吸窘迫。在评估有胸腔和腹腔积液的患者时，应将肝叶扭转作为鉴别诊断考虑。
