摘要
目的分析胆囊腺肌病的影像表现,提高诊断正确性。方法回顾性分析经手术病理证实的16例胆囊腺肌病患者的临床及影像资料,12例行64排螺旋CT平扫及多期动态增强扫描,7例(3例为CT检查后)MRI平扫及动态增强扫描。结果 16例胆囊腺肌病中,CT及MRI平扫表现为胆囊底部壁不均匀或结节状增厚9例,胆囊壁弥漫性增厚4例,胆囊颈及颈体交界处壁节段性增厚3例;出现典型Rokitansky-Aschoff窦(R-A窦)8例;合并结石3例。CT及MRI增强表现为动脉期黏膜强化,门静脉期强化范围进展,延迟期持续强化,R-A窦腔内无强化。结论CT、MRI平扫及增强扫描对胆囊腺肌病的诊断及鉴别诊断有重要价值;MRI显示R-A窦腔更好且具有确诊意义。
Objective To analyze imaging manifestations of gallbladder adenomyomatosis and to improve the diagnosis accuracy. Methods The clinical data and imaging manifestations of 16 patients with gallbladder adenomyomatosis proved by surgery were retrospectively analyzed. 12 cases underwent plain spiral CT and dynamic contrast enhanced spiral CT , and 7 cases （including 3 cases underwent CT examination） underwent plain MRI and dynamic enhanced MRI. Results Among 16 cases, 9 cases showed irregular or nodular thickening of the gallbladder bottom wall, 4 cases showed diffuse thickening of the gallbladder wall, 3 cases showed segmental thickening of the gallbladder neck or neck and body junction region. 8 cases showed typical Rokitansky-Aschoff sinus （ R A sinus）. 3 cases were accompanied with cholelithiasis. On CT and MRI enhanced images, the lesions showed mucosa enhancement at arterial phase, and continued to enhancement at portal venous phase and delay phase, the R A sinus cavity without enhancement. Conclusion CT and MRI plain and en- hanced scan has important value in diagnosis and differential diagnosis of gallbladder adenomyomatosis. MRI is better to display R A sinus cavity, which can confirm the diagnosis.
