We present the sonographic findings of tumoral calcinosis in two patients compared with conventional radiography, CT, and MRI. Sonography in both patients demonstrated fluid-sedimentation levels, with more echogenic debris layering dependently. This appearance has been referred to as the "sedimentation sign" on conventional radiography and results from dependent layering of hydroxyapatite crystals within cystic spaces of the lesion. There are only three reported cases in the world literature of sonographic findings in patients with tumoral calcinosis. We describe the first two cases of sonography demonstrating the "sedimentation sign," which may aid in the diagnosis of tumoral calcinosis.
我们展示了两名肿瘤性钙化患者的超声检查结果，并与传统X线摄影、CT和MRI进行了比较。两名患者的超声检查均显示出液-沉积水平，更多的高回声碎屑呈依赖性分层。这种表现被称为传统X线摄影中的“沉积征”，是由羟基磷灰石晶体在病变囊性空间内的依赖性分层所致。在世界文献中，仅有3例关于肿瘤性钙化患者超声检查结果的报道。我们描述了首例超声显示“沉积征”的两例病例，这可能有助于肿瘤性钙化的诊断。
