男性乳腺发育症的超声表现和诊断评估

Ultrasonic appearance and diagnostic evaluation of gynecomastia

目的了解男性乳腺发育症的年龄特征和超声图像表现。方法回顾性分析我院近10年经病理证实和临床随访诊断的1618男性乳腺发育症患者的临床、超声和病理资料。结果 1618例患者年龄呈双峰分布,发病高峰为16～20岁,其次为36～40岁。其声像图表现可分为结节型(41.9%)、树根型(11.6%)和类女性乳腺型(46.5%);手术组83例腺体层厚度(12.2±4.3)mm,与非手术组1535例腺体层厚度(8.3±4.8)mm比较差异有统计学意义(P<0.05),超声诊断男性乳腺发育症的敏感性为92.0%,特异性为94.7%,准确性为93.3%。结论超声测量男性乳腺腺体厚度是临床治疗的客观依据,超声检查可作为首选。

Objective To understand the age distribution and ultrasonic appearance of gynecomastia. Methods The clinical, ultrasonic and pathological data of 1618 patients with gynecomastia confirmed by pathology and clinical follow up for last ten years in our hospital were retrospectively analyzed. Result Most of the patients were 16-20 years old,and the patients were 36-40 years old followed. The ultrasonic images were was categorized into nodule type （41.9%）, flame shaped type （11.6% ） and female like breast type（46.5% ）. There was significant difference of gland thickness between surgical type（ 12.2 ± 4.3 ） mm and non-surgical group（ 8.3 ~ 4.8 ） mm（P 〈0.05 ）.The sensitivity, specificityand accuracy of ultrasound in diagnosis of gynecomastia were 92.0%, 94.7% and 93.3%, respectively. Conclusion The measurement of gland thickening in male by ultrasonography can be an objective indicator for clinical therapy, it can be used as the preferred diagnostic technique.
