A Case of Ultrasound-Guided Intervention Therapy for a Beaver Tail Liver with Hepatic Abscess

Objective: To report a case of beaver tail liver accidentally discovered by preoperative examination, and review relevant literature to improve the understanding of the anatomical variation of the liver. Methods: Analysis of a case of beaver tail liver incidentally discovered during preoperative examination for hepatic abscess in our hospital in June 2023. Combining domestic and foreign literature, the etiology, clinical manifestations, diagnosis, differential diagnosis, and treatment of beaver tail liver are discussed. Results: The patient was admitted due to abdominal pain and fever, with no other specific discomfort. An incidental finding of a beaver tail liver was discovered during imaging examinations. Conclusion: The beaver tail liver is a variant in hepatic anatomical morphology with nonspecific clinical manifestations. It is often incidentally discovered through imaging examinations such as ultrasound, CT, or MRI. Treatment is only necessary when the beaver tail liver is associated with hepatitis or tumors;otherwise, it does not require specific treatment.

獭尾肝的影像诊断

目的 :探讨獭尾肝的影像标准和应用价值。方法 :回顾分析 4 4例獭尾肝的CT和MR表现。结果 :男 2 5例 ,女 19例。左肝向左伸延部分超越腋中线 ,其中 2 9例达到腋后线 ,与左外叶连接处位于左腋前线附近 ,可相对狭窄。结论 :肝左外缘向左后方延长、弯曲 ,尖端超过腋中线 ;延长部分肝组织与正常左外叶血管相连 ,平扫及增强扫描 ,与其余肝组织密度 /信号相仿 ;左叶间裂位于椎体右缘右侧等提示为獭尾肝。

獭尾肝一例并文献复习

目的报道一例术前检查意外发现的獭尾肝病例,并复习相关文献以提高对该肝脏解剖学变异的认识。方法分析我院2020年1月因右肝内胆管结石收治行术前CT检查确诊的肝獭尾肝1例,并结合国内外相关文献,对本病的发病机制、临床表现、诊断、鉴别诊断、治疗进行讨论分析。结果患者因右肝内胆管结石症状间歇性腹痛入院,其余并无特殊不适,因术前行CT检查意外发现獭尾肝。结论獭尾肝为肝脏解剖形态学上的一种变异,其本身无特异性临床表现,常因B超、CT或MRI等影像学检查意外发现,若獭尾肝合并肝炎或肿瘤时才需要治疗,其本身无需特殊治疗。
