腹腔非脏器实质性肿块的B超检查与病理检查结果对照分析

Comparison of Ultrasonic and Pathological Diagnosis of 117 Cases of Nonorgans Solid Masses

本文腹腔肿块中肿瘤占76.0%,其中恶性肿瘤占57.0%,良性肿瘤19.0%,炎症肿块24.0%。超声诊断符合率为78.5%,定位诊断符合率为96.0%。恶性肿瘤回声强弱不一,分布不均,境界不规整,常伴有腹水,良性肿瘤回声较均匀,境界较规整,不伴有腹水;炎症肿块中以结核性为多,声像类似转移癌,可见腹水,其中有飘浮的细光带,活动度低,有些病例可见小椭园形的腹腔淋巴结声像。并讨论鉴别诊断及有关问题。

This article reported that tumors 76% of 117 patients patients with extraperitoneal solidmasses. Malignant tumors. benign tumors and inflammatory masses occupied 57 % 、19 % and 24 respectively. The overall accurate ultrasonic diagnosis rate was 78. 5%. Metastasis were predominant a-mong the malignant tumors and appeared as clusters of heterogeneous echoes with obscured or irregular contour surrounded by dark or pseudopodium areas with ascites. The echoes of benign tumors were homogeneous , well-defined and fairly uniform without ascites. Tuberculous masses were predominant a-mong the inflammatory lesions with its ultrasonic characters similar to that of metastatic cancers. Which shown finely optical zone with flapping patern will indicate that the activity of the tumor is low. Elliptical lowe choes of tuberculous lymph nodes were explored.
