摘要
目的研究脂肪肝背景下低回声病灶的超声声像图特点,旨在提高诊断准确率。方法 对45例常规超声体检发现脂肪肝合并低回声病灶的超声声像图特点进行回顾性分析,依据声像图表现的不同,将其分为3组进行研究。结果Ⅰ组病变表现为境界清晰低回声,内部回声均匀或欠均匀,病灶区及周围未测及血流。这组病变共28例,其中CT增强扫描证实肝血管瘤22例,孤立性肝坏死结节6例。Ⅱ组病变均表现为边缘模糊不清的低回声,内部回声欠均匀,病灶区及周围可见彩色血流信号,对周围组织压迫不明显。这组病例共10例,均为正常肝组织残留。Ⅲ组病变均表现为以边缘不清的低回声为主,内部回声不均一,对周围组织压迫明显,病灶区及周围可见彩色血流信号。这组病例共7例,5例为原发肿瘤转移,1例为肝结核,1例为肝脓肿。结论脂肪肝背景下肝内低回声病灶,多以正常肝组织残留及血管瘤多见,其超声图像具有一定的影像学特点,可配合增强CT进一步明确诊断。
Objective To investigate ultrasound feature of hypoecho nodes in fatty liver in order to improve the diagnosis rate.Methods All of 45 cases who took regular physical examination is investigated.The characteristic ultrasound feature of hypoecho nodes is retrospective analysis.According to the difference of ultrasound feature,these cases are divided into three groups.Results Group Ⅰ： hypoecho nodes with clear margin,homogeneous or heterogeneous inside,no blood found in the nodes and surrounding nodes.The total number of this group is 28 cases,including 22 hemangioma and 6 solid necrosis nodes,which were proved by CT enhanced examination.Group Ⅱ：hypoecho nodes with non-clear margin,heterogeneous inside and color blood signal inside and surrounding the nodes.The total number is 10 cases,which were all normal liver residue.Group Ⅲ： hypoecho nodes with obscure margin,heterogeneous inside,surrounding tissue compared by nodes,and color blood signal found inside and surrounding tissue.The total number is 7 cases including 5 metastasis,1 tuberculosis,and 1 abscess.Conclusion Most of the hypoecho nods in fstty live are normal liver residue and hemangioma.They are some typical ultrasound feature and proved by enhance CT examination.
