The aim of this study was to investigate the value of color Doppler flow imaging (CDFI) in the diagnosis of glomus tumors in the extremities.
Sonography results of 62 nodules of 50 patients with glomus tumors in the extremities confirmed by surgery and pathology were analyzed retrospectively.
The sex ratio in the group of 50 patients was (female:male) = 5.25:1. Glomus tumors were more common in women aged 30-40 years. 84 % (42/50) of glomus tumors occurred in the fingers, with the thumb being the most common. 2D results showed that 64.52 % (40/62) of 62 nodules were hypoechoic, 30.65 % (19/62) were heterogeneous echo, 4.84 % (3/62) were hyperechoic; 64.52 % (40/62) had a clear border, while 35.48 % (22/62) had an unclear border. CDFI showed that 38.71 % (24/62) had visible rich blood in the tumor, 35.48 % (22/62) had little visible blood in the tumor, and 25.81 % (16/62) had no significant intratumoral blood flow. Of the 50 patients, 92 % (46/50) showed a fixed contact pain, were sensitive to cold stimuli, which was improved by hot water and air, and for which anti-inflammatory treatment was ineffective.
Glomus tumors in the extremities had certain ultrasound features, and its internal blood flow was diverse. Understanding this feature may be helpful for the diagnosis of non-typical glomus tumors.
本研究旨在探讨彩色多普勒血流成像(CDFI)在四肢血管球瘤诊断中的价值。
回顾性分析50例经手术及病理证实的四肢血管球瘤患者62个结节的超声检查结果。
50例患者中,男女比例为(女∶男)=5.25∶1。血管球瘤在30 - 40岁女性中更为常见。84%(42/50)的血管球瘤发生在手指,其中拇指最为常见。二维超声结果显示,62个结节中64.52%(40/62)为低回声,30.65%(19/62)为混合回声,4.84%(3/62)为高回声;64.52%(40/62)边界清晰,35.48%(22/62)边界不清。CDFI显示,38.71%(24/62)肿瘤内部可见丰富血流,35.48%(22/62)肿瘤内部可见少量血流,25.81%(16/62)肿瘤内部无明显血流信号。50例患者中,92%(46/50)表现为固定性触痛,对冷刺激敏感,用热水及热气可缓解,抗炎治疗无效。
四肢血管球瘤具有一定的超声特征,其内部血流情况多样。了解这一特征可能有助于非典型血管球瘤的诊断。
