报告经手术病理证实的肾上腺囊肿11例，讨论其病因、病理及影像学诊断。影像学检查是肾上腺囊肿术前诊断的主要依据，平片肾上腺区出现蛋壳样钙化为其特征性表现；CT和超声检查对囊肿的诊断有一定特征性，CT表现为肾上腺区边缘光滑、均匀水样密度的囊性占位，增强扫描无强化；MRI对囊肿的诊断无特征性，对定位诊断有帮助。上腹部的占位性病变，应综合多种影像手段进行定位和定性诊断。
Reported 11 cases of adrenal cysts confirmed by surgery and pathology to discuss the etiology, pathology and imaging diagnosis. Imaging examination is the main basis for preoperative diagnosis of adrenal cysts. The appearance of eggshell-like calcification in the adrenal glands of the plain film is a characteristic feature. CT and ultrasonography have certain characteristics in the diagnosis of cysts. CT shows a smooth and uniform edge of the adrenal region. The cystic lesion area of the water sample density was not enhanced by enhanced scans; MRI had no characteristic diagnosis of cysts, which was helpful for localization diagnosis. In the space-occupying lesions of the upper abdomen, a variety of imaging methods should be used for positioning and qualitative diagnosis.
