例1患者男,52岁。2年前无明显诱因出现双侧股骨疼痛,影像学检查示:左侧多根肋骨骨质破坏,双侧股骨上段骨质病变,考虑棕色瘤。甲状旁腺素:1 712.5pg/ml。彩超检查:左侧甲状腺背侧可见3.58cm×0.64cm边界清晰的条索状的极低回声,内部回声欠均匀,CDFI其内可见丰富的血流信号,频谱为低阻动脉型。超声造影:经肘静脉团注SonoVue造影剂2.4 ml后,12s时,左侧甲状腺背侧低回声病灶开始快速均匀强化增强,较甲状腺增强时间早、强度高;55s时,开始廓清,呈低增强(图1)。术后病理结果:甲状旁腺腺瘤。
Example 1 patient male, 52 years old. Two years ago there was no obvious incentive for bilateral femoral pain, imaging studies showed that: the left side of multiple ribs bone destruction, bilateral upper femur bone lesions, consider brown tumor. Parathyroid hormone: 1 712.5 pg / ml. Color Doppler ultrasound examination: the left thyroid dorsal visible 3.58cm × 0.64cm clear border cord-like low echo, the internal echo less uniform, CDFI its rich blood flow signal can be seen within the spectrum of low-resistance type. Contrast ultrasound: SonoVue contrast agent 2.4 ml bolus injection of the elbow vein, 12s, the left thyroid dorsal hypoechoic lesions began rapidly and uniformly enhanced, compared with the thyroid enhancement earlier, higher intensity; 55s, began to clear, was low enhancement (figure 1). Postoperative pathological findings: parathyroid adenoma.
