超声诊断急性化脓性甲状腺炎的价值

摘要

Objective To explore the value of ultrasound diagnosis of acute suppurative thyroiditis (AST)Methods The thyroid ultrasonic characteristics of 11 patients with AST and 20 normal subjects were analyzed retrospectively. Results In the 11 patients,lesions were located in the left side in 9 cases,lesions of the left side spreading to the isthmus in 3 cases,and lesions were located in the right side in 2 cases. The lesions with irregular shape,obscure border,and inhomogeneous echogenicy,linked with the soft tissue around thyroid glands were in 10 cases. The lesions with ellipse shape, sharp border and homogeneous echogenicy, located completely inside of thyroid gland were in 1 case. The neck lymphadenectasis could be observed in 5 cases. Blood flow signals could be detected mainly at the border area or periphery area of lesions, and inside the abnormal lymph nodes. Compared with normal group, the anterior-posterior diameter and left-right diameter in the group with AST lesions were enlarged(P＜0.05). The superior artery peak systolic velocity(PSV)in the side of thyroid with AST lesions increased(P＜0. 05). Among dynamic ultrasound followed-up of 8 patients,the size of lesions increased in 5 cases,and reduced in 3 cases. Conclusions Ultrasound plays an important role in diagnosis of AST.%目的 探讨超声诊断急性化脓性甲状腺炎(AST)的价值.方法 回顾性分析11例AST患者和20例健康对照者的甲状腺超声影像资料.结果 11例AST患者中,病灶位于左侧9例,其中蔓延至峡部3例;位于右侧2例.10例病灶与甲状腺周围软组织相连,边界不清,形态不规则,内部回声不均匀;1例病灶完全位于甲状腺内部,呈椭圆形,边界清晰,内部回声较均匀.病灶血流信号主要分布于边缘区或周边区.颈部淋巴结肿大5例,血流信号较丰富.与正常组比较,- AST患者患侧甲状腺前后径和左右径增大(P<0.01),患侧甲状腺上动脉血流收缩期峰速度(PSV)增快(P<0.01).超声动态随访8例,病灶缩小5例,增大3例.结论 超声诊断AST具有重要临床价值.
