甲状旁腺囊肿的超声诊断临床误诊分析

Clinical misdiagnosis of ultrasonography on parathyroid cyst

[目的]探讨甲状旁腺囊肿的超声诊断临床特点,以避免误诊。[方法]回顾性分析2012年6月—2013年5月3例甲状旁腺囊肿误诊病例的超声诊断图像资料。[结果]3例患者病灶均位于左侧甲状腺下极背侧,均经手术、病理学证实。超声声像图共同表现:病灶呈圆形或椭圆形的无回声区,边界清晰,包膜完整,壁薄且光滑。甲状旁腺囊肿与甲状腺两者包膜表现为锐角。[结论]甲状腺超声检查时,甲状旁腺区域的病变,尤其是甲状腺下部,均要考虑与甲状旁腺来源的病变鉴别。

Objective To study clinical ultrasonography characteristics on parathyroid cysts , so as to avoid misdiagnosis of that in clinic . [ Methods] The ultrasonic image data on parathyroid cyst of 3 misdiagnosed cases hospitalized from June 2012 to May 2013 were retrospectively analyzed . [ Results] The foci of 3 cases were located in the dorsal area under the left lobe distal polar of thyroid , and were con-firmed by surgery and pathology .The common performance of ultrasonic images：round or oval anechoic ar-ea, clear boundary , integrity membrane , thin and smooth wall .The envelop between parathyroid cyst and thyroid presented with acute angle . [ Conclusion] In thyroid ultrasonic examination , lesions in the par-athyroid gland area , especially around the inferior pole of thyroid , should be considered to be differentiated from that of parathyroid disease .
