| 目的 探讨肝脏局灶性病变的不典型CEUS特征及其误诊原因。 方法 回顾性分析与手术或穿刺病理结果不符的21例肝脏局灶性病变的CEUS特征,分析其误诊原因。 结果 21例CEUS检查误诊患者中,9例病理诊断为恶性病灶,其中8例为肝细胞癌(HCC),1例为肝转移癌,CEUS均误诊为良性病灶;12例病理诊断为良性病灶,其中3例为结节性肝硬化伴脓肿或坏死,3例为肉芽肿伴坏死,3例为血管瘤,1例为局灶性结节增生(FNH),1例为炎性假瘤,1例为血管平滑肌脂肪瘤,CEUS将其中10例误诊为恶性病灶,2例误诊为不同病种间良性病灶。 结论 提高对少见病的认识,加深对各类相关分子学科知识的理解,仔细观察回放动态图像,综合分析造影过程各时相的特点,结合常规超声及临床检查结果,必要时行穿刺活检,可提高CEUS诊断的准确性。 |

| Objective To observe the atypical features and the causes of misdiagnosis of contrast-enhanced ultrasonography (CEUS) in focal liver lesions. Methods The images in 21 cases misdiagnosed with CEUS were reviewed retrospectively, and the causes of misdiagnosis were analyzed. Results In the 21 patients, 9 lesions were pathologically diagnosed as malignant, including 8 hepatocellular carcinomas (HCC) and 1 liver metastasis, while were misdiagnosed as benign lesions with CEUS. The other 12 lesions were proved benign pathologically, including 3 nodular cirrhosis associated with abscesses or necroses, 3 granuloma associated with necroses, 3 hemangiomas, 1 focal nodular hyperplasia (FNH), 1 inflammatory psudotumor and 1 angiomyolipoma, among which 10 were misdiagnosed as malignant lesions and 2 were misdiagnosed as other benign lesions with CEUS. Conclusion Understanding the rare disease and information of related subjects, reviewing the image carefully, analyzing the features on CEUS generally, combining conventional ultrasonography and clinic finings may improve the diagnostic accuracy of CEUS. |
