BACKGROUND
To describe the characteristic magnetic resonance imaging (MRI) findings of gallbladder adenomyomatosis in two cases.
METHODS
Two patients had abdominal MRI findings of gallbladder adenomyomatosis confirmed at cholecystectomy.
RESULTS
The surgical specimen showed findings typical of adenomyomatosis, including marked thickening of both epithelial and muscular elements with multiple Rokitansky-Aschoff sinuses. On gadolinium-enhanced spoiled gradient-echo images and single-shot fast spin-echo images, mild gallbladder wall thickening with multiple intramural cystic components from Rokitansky-Aschoff sinuses were readily visualized.
CONCLUSION
Adenomyomatosis of the gallbladder can be detected and diagnosed from MRI findings.
背景
描述两例胆囊腺肌增生症的特征性磁共振成像（MRI）表现。
方法
两名患者经胆囊切除术证实有胆囊腺肌增生症的腹部MRI表现。
结果
手术标本显示出腺肌增生症的典型表现，包括上皮和肌层明显增厚，伴有多个罗-阿窦。在钆增强扰相梯度回波图像和单次激发快速自旋回波图像上，可清晰看到胆囊壁轻度增厚，伴有来自罗-阿窦的多个壁内囊性成分。
结论
胆囊腺肌增生症可通过MRI表现进行检测和诊断。
