目的探讨罗-阿氏窦(RA窦)在影像学上诊断胆囊腺肌增生症(GBA)的作用与限度。方法26例术前均行B超检查,6例行CT检查。比较经组织学证实的GBA患者的影像学和病理学资料,结合文献复习,分析RA窦的影像学基础及其GBA影像学诊断依据。结果本组术前明确诊断GBA仅3例,诊断率为11.5%,其中2例由CT诊断,1例由B超诊断,其特征表现为在增厚变形的胆囊壁上显现RA窦,并突入肌层,但对判定其是否已癌变无特异性。结论RA窦可以出现在GBA和胆囊癌的胆囊壁上,也可能出现在正常的胆囊壁上,正确选择影像学检查方法和仔细观察RA窦形态特征是GBA早期诊断和治疗的关键。
Objective To investigate the role and limitation of radiolucent aortic sinus (RA sinus) in the diagnosis of gingival adenomyosis (GBA). Methods Twenty-six patients underwent preoperative B-ultrasound and 6 underwent CT. Comparing the imaging and pathological data of histologically confirmed GBA patients with literature review, we analyzed the imaging basis of RA sinus and the diagnostic evidence of GBA. Results In this group, only 3 cases of GBA were diagnosed preoperatively, with a diagnosis rate of 11.5%. Two cases were diagnosed by CT and one case was diagnosed by B-ultrasound. The manifestations of this group were manifestations of RA sinus in the thickening deformed gallbladder wall, Muscle, but to determine whether it has no specific cancer. Conclusions RA sinusoids may appear on the gallbladder wall of GBA and gallbladder cancer, and may also appear on the normal gallbladder wall. Correct choice of imaging method and careful observation of RA sinusoidal features are the key to early diagnosis and treatment of GBA.
