獭尾肝的超声诊断及鉴别诊断

目的探讨超声检查在獭尾肝诊断中的价值。方法回顾性分析14例经临床证实的獭尾肝的超声表现。结果 14例獭尾肝患者,6例分别误诊为残脾、副脾代偿性增大、脾肿瘤、分叶脾及脾周血肿;其余8例超声正确诊断为獭尾肝;超声表现为左肝外叶向左后伸延,延伸部分如同尾巴样或象鼻样形态;延伸部分的肝实质回声与其余区域肝实质回声相仿;其内血管与左肝外叶相连。结论超声检查不仅能够正确的诊断先天性獭尾肝,且能与残脾、副脾代偿性增大、脾肿瘤、分叶脾及脾周血肿等鉴别。

Objective To evaluate the value of ultrasound in the diagnosis of beaver tail liver.Methods The ultrasonic manifestation of 14 cases of heaver tail liver clinically proved were analyzed retrospectively. Results 14 cases of heaver tail liver：9 males and 5 females;of which 6 cases were misdiagnosed as residual spleen、hypertrophy of the attached spleen、splenic tumor, lobulated spleen or hematoma around the spleen.The remains were diagnosed correctly.The ultrasonic manifestation of heaver tail liver was that：The left lateral lobe edge extended towards left posterior,which formed tail-like or trunk-like morphology,The echo of the extending portion was similar to the rest hepatic tissues and the vessels in the extending portion connects with that in the normal left lateral lobe. Conclusion Beaver tail liver can not only be diagnosed correctly by Ultrasound,but also be distinguished with residual spleen,hypertrophy of the attached spleen,splenic tumor,lobulated spleen or hematoma around the spleen.
