A 4-year-old castrated male domestic shorthair cat was presented with lethargy, anorexia and vomiting that did not improve with symptomatic treatment. Blood tests revealed markedly elevated liver enzymes. Abdominal ultrasound showed gallbladder abnormalities, including a small gallbladder, indistinct fundus, a continuous spiral-shaped morphology forming C- and reverse C-shaped curves, and hyperechoic fat surrounding the gallbladder. An exploratory laparotomy revealed gallbladder torsion without hepatic lobe torsion. Cholecystectomy was performed, and the prognosis was favourable.
Gallbladder torsion without hepatic lobe torsion has not been previously reported in cats. The clinical signs, diagnostic imaging features and intraoperative findings differed from those reported in humans and dogs. The unique ultrasonographic appearance seen in this case may assist with future diagnoses of this rare condition in cats.
一只4岁去势的雄性家猫出现嗜睡、厌食和呕吐症状，对症治疗后未见好转。血液检查显示肝酶显著升高。腹部超声显示胆囊异常，包括胆囊小、底部不清晰、呈连续螺旋状形态形成C形和反C形曲线，以及胆囊周围高回声脂肪。剖腹探查显示胆囊扭转但无肝叶扭转。进行了胆囊切除术，预后良好。
此前尚未有猫发生无肝叶扭转的胆囊扭转的报道。其临床症状、诊断性影像学特征及术中发现与人和犬类报道的情况不同。该病例中独特的超声表现可能有助于未来对猫的这种罕见病症进行诊断。
