【摘要】：目的研究肝脏上皮样血管平滑肌脂肪瘤(EAML)的超声表现特征。方法回顾性分析39例(41个病灶)经手术病理证实为肝EAML的声像图,分析其超声表现特征。结果肝EAML以中年女性多见。病灶大小1.5~16cm,平均(5.8±4.1)cm。超声表现为66%(27/41)病灶呈低回声,34%(14/41)呈高回声;44%(18/41)病灶内部回声不均匀;51%(21/41)边界清;17%(7/41)病灶周边可见低回声晕环。CDFI显示83%(34/41)病灶内有血流信号,其中46%(19/41)表现为周边和内部较丰富点线状血流(I型),血管扭曲杂乱,部分病灶周边有血管包绕;37%(15/41)病灶表现为周边和(或)内部少量点状、短线状血流(Ⅱ型),RI值为0.38~0.66,平均值0.50±0.10。5%(2/39)可出现局部复发和远处转移,为恶性肝EAML。结论肝EAML因其组织成分和血供特点,其灰阶声像图和CDFI表现具有一定特征性,可有助于诊断。
[Abstract]:Objective to study the ultrasonographic features of hepatic epithelioid angiomyolipoma (EAML). Methods 39 cases (41 lesions) confirmed by operation and pathology were analyzed retrospectively. Results liver EAML was mostly found in middle-aged women. The lesion size was 1.510 卤4.1 cm (mean 5.8 卤4.1 cm). The ultrasound showed that the lesions were hypoechoic 34 / 44 / 41) and hyperechoic 44 / 44 / 41). The inner echo of the lesion was not uniform 512141) the boundary of the lesion was 5121 / 41) and the low gyrus was seen around the lesion (7 / 41). The corona ring. CDFI showed that there was a blood flow signal in the lesion. Of these, 46 / 41 showed more abundant points in the periphery and interior, such as linear blood flow type I, vascular twisting and disorder, and some lesions had blood vessels around 37 / 41. The lesions showed a small number of dots in the periphery and / or in the interior. Short-line blood flow (RI = 0.38 卤0.66 with an average of 0.50 卤0.10.5 / 39) may present local recurrence and distant metastasis. Conclusion liver EAML is characterized by its tissue composition and blood supply, and its gray-scale sonogram and CDFI findings are helpful for diagnosis.
