A 5-year-old, female intact guinea pig (Cavia porcellus) presented for acute inappetence. The abdomen was severely distended and tympanic with moderate discomfort. Radiographs showed gastric distension and displacement. Gastric dilatation and volvulus were suspected. At necropsy, the left lateral liver lobe was torsed at the hilus and infarcted. Histopathology showed regionally extensive coagulative necrosis and markedly congested sinusoids, causing marked hepatic cord atrophy and dissociation. Final diagnoses were severe gastric dilatation with left lateral liver lobe torsion (LLT) and regionally extensive liver infarction, and hemoabdomen. Reports of LLT in guinea pigs are likely underrepresented in the literature. LLTs should be considered in guinea pigs presenting for acute inappetence and abdominal distension. Laboratory tests and abdominal ultrasound can help differentiate LLT from other gastrointestinal pathologies seen in guinea pigs, such as gastric dilatation and volvulus. Early recognition of LLT in guinea pigs could potentially improve patient outcomes. This is the first published report of LLT in a guinea pig.
一只 5 岁雌性未绝育豚鼠（Cavia porcellus）因急性食欲不振而就诊。腹部严重膨胀且紧张，中度不适。X 光片显示胃扩张和移位。怀疑为胃扩张和扭转。尸检时，肝左外侧叶在门脉处扭曲并梗死。组织病理学显示区域性广泛的凝固性坏死和明显充血的窦状隙，导致明显的肝索萎缩和分离。最终诊断为严重的胃扩张伴肝左外侧叶扭转（LLT）和区域性广泛的肝梗死，并伴有血腹。豚鼠 LLT 的报告在文献中可能被低估了。对于出现急性食欲不振和腹胀的豚鼠，应考虑 LLT。实验室检查和腹部超声有助于将 LLT 与豚鼠中常见的其他胃肠道疾病（如胃扩张和扭转）区分开来。早期识别豚鼠的 LLT 可能会改善患者的预后。这是首例关于豚鼠 LLT 的报告。
