Eight cases of carotid body tumor diagnosed by Bmode ultrasonic imaging

This paper reports that 8 patients with carotid body tumors were diag-nosed by B-mode ultrasonic imaging.Among them,only 3 were originally clinicallydiagnosed as having the disease.The features of carotid body tumors in the 8cases,seen by B-mode ultrasonogram,are described.It is considered thatultrasonography of carotid body tumors is specific,trauma-free,accurate andsimple,and it may be an important method in identifying and diagnosing the dis-ease.

超声检查对Krukenberg肿瘤诊断的临床价值

对30例经手术病理证实的Krukenberg肿瘤（库肯勃瘤）患者的超声或双工彩色多普勒超声扫查图像进行了分析。结果表明：病变累及双侧26例，占86.7％。超声首先提示本病诊断有22例，定性诊断正确率为73.3％。本病典型声像图特征为实质性肿块内有一至数个大小不等的类圆形的无回声区，外形如肾形或椭圆形，大多有包膜，边界清楚。本组此型占85.7％（48/56个肿块），其平均大小为9.5cm。其中6例（10个）库肯勃瘤患者同时作了彩色多普勒超声扫查，发现卵巢肿瘤周边或内部有彩色血流信号，呈动脉频谱，为高速低阻型，其测值为ps50～68cm/s（x^-±s为58.0±4.8cm/s），RI：0.38～0.46（x^-±s为0.41±0.03）。病理对照发现，病灶内类圆形无回声区系印戒细胞分泌粘液所致。
