超声对手部血管球瘤的诊断价值

High Frequency Ultrasonography and Color Doppler Flow Imaging for Evaluating Diagnosis of Glomus Tumors in Hands

目的探讨超声及彩色多普勒血流显像(CDFI)对手部血管球瘤的诊断价值。方法分析了58例手部血管球瘤的声像图特征及病理结果,并与X-线,MRI等影像检查结果进行了对照。结果手部血管球瘤的主要声像图特征:(1)软组织内肿瘤,呈现以低回声为主的混合性回声;(2)肿瘤无包膜回声,形态规则,多呈椭圆形,与周围组织境界清晰;(3)瘤体内多数可探及丰富血流信号(52/58)。超声术前诊断与术后病理符合率为89.7%,为手术方案的制定提供了重要依据。结论超声对手部血管球瘤的诊断有重要临床价值,可作为手部血管球瘤的首选影像学诊断方法。

Objective To evaluate high frequency ultrasonography in the diagnosis of glomus tumors of the hand. Methods The ultrasonographic and color Dopper flow Imaging （CDFI） features in 58 patients were retrospectively reviewed and compared with those of X-ray, Magnetic resonance imaging （MRI） and histology. Results The sonograms manifested as follows： 1） glomus tumors appeared mixed echoes mainly heterogeneous hypoechoic masses; 2） regular shape with sharp demarcation without clear capsule echoes; 3） many scattered color Doppler flow signals could be found in most cases （52/58） . The ultrasonic diagnosis had coincident rate of 89.7% with histological results. Conclusions Ultrasonography is the excellent method for diagnosis of glomus tumors in the hands. It can provide important basis for surgical planning.
