摘　　要：目的 研究脂肪肝中圆形低回声病灶的超声特征及临床意义。方法 本组25例均行常规超声检查,并行CT检查,同时查AFP,超声随访3～36个月。结果 超声检出正常肝组织残留21例(84％),声像图表现为无球体感、边界欠清晰、大小在1.8～2.5cm之间、内无血流信号、周围组织及管道无受压、破坏现象;血管瘤2例(8％),声像图表现为圆形,边界清晰,低回声内有网状回声;转移性肿瘤2例(8％),肿块的周边可见低～无回声的细带。CT检查结果与超声检查基本一致。结论 脂肪肝内圆形低回声病灶以正常肝组织残留多见,超声可以做出基本诊断,CT可以进一步诊断。Objectve To investigate ultrasound feature of hypoecho nodes in fatty liver, and its clinical signification. Methods All of 25 cases is investigate group had proceeded routine ultrasound and CT examination. At the same time everyone was given the examination of AFP. Ultrasound follow- up lasted for three to thirty- six months. Results Residual normal liver parenchymas were found in the livers of 21 cases by ultrasound . Acoustic image appears as without spheric sense and boundary was indistinct, the size was under 2. 5cm. Its inside had no hemokinetic signal. The surrounding tissues and ducts were without the phenomenon of compression and destruction. Two cases of hepatic hemangioma(8% ) which acoustic images appeared as round and boundary were distinctness, and the inside low echo had got reticulation echo. Two cases of metastatic tumor( 8 %) were presented hypoecho acoustic halo. CT examination confirmed the conclusion of ultrasound findings. Conclusion Hypoecho in the middle round node of fatty liver mostly represents the residual normal liver parenchymas. Ultrasound could work out basic diagnosis, CT could improve diagnosis.
