背景:疣状静脉畸形(VVM),以前被称为“疣状血管瘤”,“是一种罕见的血管畸形。
目的:对VVM的超声特征知之甚少。本研究旨在显示VVM的常规US和弹性成像特征。
方法:回顾性评估了103例VVM患者的US检查结果。
结果:在灰度超声图像上,98例(95.1%)病变显示皮下脂肪从皮肤穿过肌肉浸润到深筋膜。其他5例(4.9%)位于皮下层,无皮肤受累。大多数(96.1%)病变为高回声。此外,71.8%的病变为异质性,其中68.9%的利润率不明确。5.7%和10.7%的VVM病例存在钙化和可见血管,分别。通过彩色多普勒超声,所有病变均发现血管密度低,4.9%的病变在受压后血流增强.在67.0%的病变中观察到静脉谱。弹性评分为2.66±0.48。
结论:VVM的诊断在临床上具有挑战性。然而,我们发现,大多数VVM病变呈现独特的超声成像特征.这些超声检查结果可能有助于VVM诊断的准确性。尤其是那些没有表皮变化和缺乏真皮参与的人。
Verrucous venous malformation (VVM), previously called \"verrucous hemangioma,\" is a rare type of vascular malformation.
Little is known about the ultrasonographic characteristics of VVM. The present study aimed to show the conventional US and elastographic features of a VVM.
The US findings in 103 patients with VVMs were retrospectively evaluated.
On gray-scale ultrasound images, 98 (95.1%) lesions showed subcutaneous fat infiltration from skin across muscle to deep fascia. The other 5 (4.9%) sat in the subcutaneous layer with no skin involvement. Most (96.1%) lesions were hyperechoic. Furthermore, 71.8% of lesions were heterogeneous, 68.9% of which were with ill-defined margins. Calcifications and visible vessels were present in 5.7% and 10.7% of the VVM cases, respectively. By color Doppler ultrasound, all lesions were found with low vascular density and 4.9% showed enhanced blood flow after compression. Venous spectrum was observed in 67.0% of lesions. The elasticity score was 2.66 ± 0.48.
Diagnosis of a VVM is challenging in the clinic. However, we found that most VVM lesions present distinctive ultrasound imaging characteristics. These ultrasound findings may well contribute to the accuracy of VVM diagnosis, especially in those with the absence of epidermal changes and the lack of dermal involvement.
