甲状腺超声检查时对偶发性甲状旁腺腺瘤的发现和诊断

Detection and Diagnosis of Parathyroid Incidentalomas during Thyroid Ultrasound

目的 探讨对甲状腺疾病患者进行甲状腺超声检查时偶发性甲状旁腺腺瘤发现率。方法 对 1667例患者进行甲状腺超声检查 ,甲状腺实质后方组织发现椭圆形、均匀低回声团块记为可疑病例 ,并对其进行甲状旁腺功能亢进的血生化检查 ,与手术病理对照。结果 发现可疑病例 2 2例 ,与手术病理结果比较 ,其中 8例为甲状旁腺腺瘤 (3 6.4% ,8/ 2 2 ) ,偶发性甲状旁腺腺瘤的发生率为 0 .47% (8/ 1667)。结论 甲状腺超声检查时可以发现偶发性甲状旁腺腺瘤。对于甲状腺疾病患者 ,超声对于预先确定甲状旁腺组织的价值较低。

Objective To evaluate the incidence of incidentally finding parathyroid adenomas (incidentalomas) in patients under ultrasound examination of the neck for thyroid disease. Methods A total of 1667 patients underwent ultrasound of thyroid. The patient with a hypoechoic, oval compatible nodule was called suspectable patient. Biochemical screening for hyperparathyroidism was also performed. The result of ultrasound was compared with the operation and pathological diagnosis. Results Twenty two suspectable patients were found, including 8 (36.4%) parathyroid adenomas, the incidence of incidentally found parathyroid adenomas was 0.47%(8/1667). Conclusion Parathyroid adenoma may be incidentally discovered during undergoing ultrasound of the thyroid. In patients with thyroid disease, the positive predictive value of ultrasound in the identification of parathyroid tissue was low.
