To describe the gray-scale Doppler and sonographic features of a series of subcutaneous angioleiomyomas.
The sonographic appearances of 10 pathologically proven angioleiomyomas were retrospectively reviewed; 4 in women and 6 in men, with an age range from 33 to 77 years. We evaluated size, shape, echo pattern, margins, location, relationships with adjacent structures, and vascularity. Examinations were performed using a multifrequency linear array transducer (9-11 MHz) connected to a Logiq 500 scanner (GE, Milwaukee, Wl).
All tumors were subcutaneous and located in the extremities (7 in the lower extremities, 3 in the upper extremities). The sizes ranged from 0.6 to 6.4 cm, with an average size of 2 cm. All of the lesions were hypoechoic with well-defined margins, and 9 were oval. Intratumoral calcifications were observed in two patients. Vascularity was easily detected in all of them, and 4 tumors had a clear vascular pedicle. The spectral Doppler analysis performed in 5 cases, revealing a low-resistance arterial waveform in 4 patients.
Although angioleiomyomas are uncommon soft tissue tumors, the presence of a well-defined, hypoechoic, vascular subcutaneous tumor in the extremities should raise the possibility of such a diagnosis.
描述一系列皮下血管平滑肌瘤的灰阶多普勒及超声特征。
回顾性分析10例经病理证实的血管平滑肌瘤的超声表现；其中女性4例，男性6例，年龄范围为33至77岁。我们评估了肿瘤的大小、形状、回声模式、边界、位置、与相邻结构的关系以及血管情况。检查使用连接到Logiq 500扫描仪（GE，密尔沃基，威斯康星州）的多频率线性阵列换能器（9 - 11 MHz）进行。
所有肿瘤均位于皮下，且均位于四肢（下肢7例，上肢3例）。大小范围为0.6至6.4 cm，平均大小为2 cm。所有病变均为低回声，边界清晰，9例为椭圆形。2例患者观察到瘤内钙化。所有肿瘤均易于检测到血管，4例肿瘤有清晰的血管蒂。对5例进行了频谱多普勒分析，4例患者显示为低阻力动脉波形。
尽管血管平滑肌瘤是罕见的软组织肿瘤，但四肢出现边界清晰、低回声、有血管的皮下肿瘤应提高对此类诊断的可能性。
