摘要

目的：

探讨肾脏巨大血管平滑肌脂肪瘤（angiomyolipoma，AML）彩色多普勒超声及超声造影表现，提高超声对肾脏巨大AML的诊断准确度，为临床诊断和治疗提供可靠依据。

方法：

分析23例经病理学检查证实为肾脏巨大AML患者的图像特征，包括与肾脏位置关系、形态、大小、边界、内部回声及超声造影增强模式等特征。

结果：

23例肾脏巨大AML患者，右肾10例，左肾13例（其中2例有2个肿块），共计25个肿块；25个肿块均向肾外生长突出于肾脏轮廓之外，肾皮质和/或集合系统受挤压；20个肿块呈高回声，其中15个呈较为均匀的高回声，5个内部回声不均匀，呈多发斑片状高回声夹杂不规则低回声；3个呈不均匀混杂回声（2个肿块内部出血坏死，1个肿块破裂至肾周血肿）；2个呈低回声。8例行超声造影检查，其中3例为快进慢出增强模式，5例为慢进慢出增强模式。

结论：

彩色多普勒超声对肾脏巨大AML具有较高的诊断价值，超声造影可以显示肿块血供情况及造影剂灌注模式，尤其对破裂出血肿块具有很高的诊断价值。

Abstract

Objective:

To investigate the color Doppler ultrasound and contrast-enhanced ultrasound findings of renal giant angiomyolipoma (AML) for improving the diagnostic accuracy of renal giant AML

and providing reliable basis for clinical diagnosis and treatment.

Methods:

A total of 23 cases of renal giant AML confirmed by pathology were analyzed

including relation to renal location

shape

size

boundary

internal echo and contrast agent perfusion mode.

Results:

There were 25 masses in 23 patients with giant AML of the kidney

inc

luding 10 cases in the right kidney and 13 cases in the left kidney (including 2 masses in 2 cases). Twenty masses were hyperechoic

15 of them were homogeneous hyperechoic

5 were heterogeneous

multiple patchy hyperechoic with irregular hypoechoic; 3 were heterogeneous mixed echo (2 masses had hemorrhage and necrosis

1 mass ruptured to perirenal hematoma); 2 were hypoechoic. 8 cases were examined by contrast-enhanced ultrasound

including 3 cases of fast in slow out enhancement mode

5 cases of slow in slow out enhancement mode.

Conclusion:

Color Doppler ultrasound has a high diagnostic value for renal giant AML. Contrast-enhanced ultrasound can show the blood supply of the tumor and the mode of contrast agent enhancement

especially for ruptured and bleeding masses.
