Sonogram characteristics and diagnostic value of ultrasound in the splenic space occupied lesion

目的研究脾脏占位病变的声像图特征及诊断价值。方法应用B超检测分析32例脾脏占位病变的声像图。结果B超对脾脏占位病变可做出初步诊断,提示不同的声像图特征,并经手术、病理及临床随访证实。结论脾脏占位病变的声像图表现为脾肿大和脾实质内局部占位回声密度的改变,依据瘤体病理结构而定。脾内占位声像图回声增强,边缘清晰者多属良性肿瘤;如出现不规则不均质的低回声团块,多属恶性肿瘤。声像图上的回声差异对于脾脏占位病变性质和来源的鉴别具有一定的实用诊断价值。

Objective To study the sonogram characteristics and diagnositc value of ultrasound in splenic space occupied lesion. Methods Sonogram characteristics of 32 cases with splenic space occupied lesion were analyzed retrospectively. Results The ultrasound of splenic space occupied lesion had different sonogram characteristics, which was useful in diagnosis. All of them were confirmed by operation and pathology as well as follow up survey. Conclusion The ultmsonographic manifestations of splenic space occupied lesion mainly included the enlargement of spleen and the alteration of the lesions＇ density which was concerned with their pathologic constructions. In general, hyperechoic lesions with clear boundary were usually benign; hypoechoic or non - homogeneous lesions were usually malignant. The difference of the ultrasonic features has diagnostic value in differentiation of benign and malignant tumor, and is helpful in seeking the source of tumor.
