BACKGROUND
To evaluate the sonographic findings of soft-tissue nonsubungual glomus tumors.
METHODS
The sonographic appearances of nine histologically proven soft-tissue glomus tumors of nonsubungual location in nine patients (mean age, 49 years; M:F = 7:2) were reviewed retrospectively. Doppler examination and surgical excision were performed in all cases.
RESULTS
The mean size of the lesions was 1 cm. The margins of the lesions were relatively well-circumscribed in eight of nine patients (89%) with an ovoid shape in seven of nine patients (78%). The vascularity was moderate to rich in all cases, with an arterial flow pattern but no arteriovenous shunt patterns. The "vascular stalk sign" was noted in six cases (67%).
CONCLUSIONS
Nonsubungual glomus tumors are rare soft-tissue tumors with abundant vascularity and arterial flow pattern.
背景
评估非甲下血管球瘤的超声表现。
方法
回顾性分析9例经组织学证实的非甲下部位软组织血管球瘤患者（平均年龄49岁；男∶女 = 7∶2）的超声表现。所有病例均行多普勒检查及手术切除。
结果
病变平均大小为1 cm。9例患者中有8例（89%）病变边界相对清晰，9例患者中有7例（78%）呈椭圆形。所有病例血管丰富程度为中度至丰富，呈动脉血流模式，但无动静脉分流模式。6例（67%）可见“血管蒂征”。
结论
非甲下血管球瘤是罕见的软组织肿瘤，血管丰富且呈动脉血流模式。
