摘　　要：目的 :探讨大网膜转移癌的超声诊断价值。方法 :观察 33例经手术或穿刺活检病理证实的大网膜转移癌的二维图像及血流特点。结果 :1大网膜转移癌可见网膜弥漫性增厚和局限性增厚 ,以局限性增厚为主 (72 .7% ) ,主要位于上腹部、右侧腹、左侧腹 ;2内部回声呈中等回声者 2 3例 ,其中 12例伴低回声结节 ,呈低回声者 10例 ,4例伴结节 ;3彩色血流显示率 2级以上为 6 0 .6 % ;4 33例大网膜转移癌同时伴网膜外转移的占 2 7.3%。结论 :超声检查大网膜是发现腹腔脏器恶性肿瘤有无腹腔转移的最直接。Objective:To investigate the sonographic findings of the great omentum metastases Methods:We studied the sonographic and color Doppler flow features of 33 cases omentum metastasis confirmed by surgery or biopsy pathology Results:①The metastases could present images of diffusive and local thickening of great omentum, mainly the latter(72 7%), locating at upper gastric region, right abdomen and left abdomen ②Internal echoes were medium in 23 cases, which included 12 cases presenting hypoechoic nodules The internal echoes were hypoechoic in other ten cases including 4 cases with nodules ③ Of the 33 patients, 20 ones (60 6%) possessed over grade 2 color flowing in color Doppler ultrasound ④The rate of extra omentum metastases was 27 3% in all 33 patients Conclusions:The great omental ultrasonography is a directive and sensitive method in detecting peritoneal cavity metastasis secondary to malignant visceral tumors
