本文旨在描述甲下血管球瘤的常见影像学特征。该研究涉及2019年1月至2022年12月收集的数据。23名患者共31个血管球瘤接受了24 MHz探头的高频超声检查。两名经验丰富的放射科医生独立评估图像，仅使用更有经验的放射科医生的数据进行后续分析。肿瘤的平均大小为4.6毫米，其中大多数表现为均匀的低回声（90.3%）。 87.1%的病例观察到远端指骨骨重塑，平均轴周损失0.8毫米，表明血管球瘤生长缓慢且扩张。多普勒图像显示54.8%的病例有强烈的血管化，64.5%的病例出现反映肿瘤血管起源的茎征。最常见的临床特征是疼痛，占 84.6% 的病例，平均疼痛量表评分为 7.0，表明尽管是良性肿瘤，但对患者的生活产生了负面影响。该研究得出的结论是，超声评估对于诊断血管球瘤非常有用，尤其是当存在多种发现时，例如骨重塑、血管增多和柄征。这种方法可以实现准确的诊断、甲周结构的观察以及适当的手术计划，最终降低复发率。© 2023。作者，获得国际骨骼协会 (ISS) 的独家许可。

This article aimed to describe the common imaging features of subungual glomus tumors.The study involved data collected between January 2019 and December 2022. Twenty-three patients with a total of 31 glomus tumors underwent high-frequency ultrasound examinations with a 24-MHz probe. Two experienced radiologists independently evaluated the images, and only data from the more experienced radiologist were used for subsequent analyses.The average size of the tumors was 4.6 mm, and most of them appeared homogeneously hypoechogenic (90.3%). Bone remodeling of the distal phalanx was observed in 87.1% of cases, with an average axial circumference loss of 0.8 mm, indicating the slow and expansive growth of glomus tumors. Intense vascularization was found in 54.8% of cases on Doppler images, and the stalk sign, reflecting the vascular origin of the tumor, was present in 64.5% of cases. The most common clinical feature was pain, reported in 84.6% of cases, with a mean pain scale score of 7.0, indicating a negative impact on patients' lives despite being benign tumors.The study concludes that ultrasound evaluation is highly useful for diagnosing glomus tumors, especially when multiple findings, such as bone remodeling, hypervascularization, and the stalk sign, are present. This method allows for accurate diagnosis, observation of periungual structures, and proper surgical planning, ultimately reducing recurrence rates.© 2023.
