Glomus tumors are rare and many have been reported to have a hypervascular appearance on color or power Doppler sonography. We report a pathologically proven case of superficial glomus tumor within the thigh with no detectable color flow signals on color or power Doppler sonography. In addition, real-time sonography showed spontaneous motions within the tumor, which were not synchronized with vascular or respiratory motions, and misled the presurgical diagnosis of a suspected parasite in a patient who had direct contact with multiple animal species. The etiology of this internal motion remains hypothetical but, if reconfirmed, this finding may be a useful adjunctive sign for the diagnosis of glomus tumors.
血管球瘤较为罕见，许多病例在彩色或能量多普勒超声检查中表现为高血管特征。我们报告一例经病理证实的大腿浅表血管球瘤，在彩色或能量多普勒超声检查中未检测到血流信号。此外，实时超声显示肿瘤内部有自发运动，该运动与血管或呼吸运动不同步，这在一名与多种动物有直接接触的患者中导致术前疑似寄生虫的误诊。这种内部运动的病因仍属推测，但如果得到再次证实，这一发现可能成为诊断血管球瘤的有用辅助征象。
