胆囊腺肌瘤的超声声像图特征及病理对照分析

Sonography of gallbladder adenomyoma and pathologic correlation

目的探讨胆囊腺肌瘤的超声声像图特征，提高本病的超声诊断与鉴别诊断能力。方法对8例经术后病理证实的胆囊腺肌瘤的超声声像图进行对照分析。结果8例胆囊腺肌瘤的超声声像图特征为局限于胆囊壁间、单发、类圆形或半圆形、较均质低回声结节，边界清晰光整，内可见散在无回声及点状强回声，多位于胆囊底部。本组5例伴发于胆囊多发结石及慢性胆囊炎。结论胆囊腺肌瘤具有典型声像图表现，并可与胆囊其他隆起性病变鉴别。

Objective To explore the features of gallbladder adenomyoma in sonogram, and improve the abilities of diagnosis and differential diagnosis. Method Sonograms of 8 patients with proven gallbladder adenomyoma were retrospectively analyzed and correlated with pathologic findings. Results Eight patients had sonographic evidence of localized intramural nodular,which were round-like and hypoechoic,with anechoic space and tiny bright echos, confined almost exclusively to the fundus of gallbladder. Five patients were also evident with associated gallstones and chronic cholecytitis. Conclusion Sonograms of gallbladder adenomyoma have marked features,which can be differentially diagnosed from other projective lesions of gallbladder.
