| 目的 对肝脏瘤样病变的超声造影图像特征进行分析总结。方法 回顾性分析经病理及其他影像学方法确诊的19例患者21个肝脏瘤样病灶的超声造影图像特征。结果 21个肝脏瘤样病灶中,超声造影确诊了16个,其中局灶性脂肪变性(FFC)7个,炎性假瘤(IPT)5个,局灶性结节增生(FNH)4个;另外4个局灶性结节增生超声造影提示肝脏良性占位病变;将1例炎性假瘤误诊为原发性肝癌(PLC)。结论 病灶超声造影后延迟相的回声与周围肝实质相比较来判断其良恶性具有重要价值。 |

| Objective To analyze the imaging characteristics of hepatic benign tumor-like lesions on contrast-enhanced ultrasonography (CEUS). Methods Twenty-one hepatic benign tumor-like lesions in 19 patients with CEUS were retrospectively analyzed; the final diagnosis was confirmed histopathologically or by other clinical imaging follow-up. Results Sixteen (16/21) benign tumor-like lesions of liver were diagnosed as focal fatty changes (FFC, n=7), inflammatory pseudotumors (IPT, n=5) and focal nodular hyperplasias (FNH, n=4). Other 4 FNH lesions were considered as benign liver lesions with CEUS. One IPT lesion was misdiagnosed as primary liver cancer (PLC). Conclusion Differential diagnosis of malignant and benign tumor-like liver lesions based on the echo of the liver lesions in the delayed-phase is important and useful. |
