摘　　要：目的：探讨肾上腺囊肿的CT、MRI表现，以提高诊断的准确率。方法：回顾性分析手术病理证实的9例肾上腺囊肿的CT、MPI表现。结果：9例肾上腺囊肿，5例行CT检查：1例呈圆形，2例呈椭圆形，2例呈分叶状。平扫囊肿密度均匀，CT值15～35HU，3例囊壁有钙化；增强扫描囊内均无强化，2例囊壁呈环形强化，3例囊壁无强化。4例行MR平扫：均呈长T1长T2异常信号，并且囊内可见分隔，分隔与液体相比呈短T1短T2异常信号，厚薄均匀，边缘光滑。结论：CT、MRI是肾上腺囊肿定位、定性诊断较为可靠和准确的方法。Objective：To evaluate CT and MR/findings of the adrenal cyst in order to improve diagnostic accuracy. Methods：Tile CT or MRI images of 9 adrenal gland cysts confirmed by pathology were retrospectively analyzed. Results：5 adrenal gland cysts with CT examination appeared as 1 round, 2 oval shaped and 2 lobulated cystic masses with fifteen to thirty-five of plain scan CT values. The cystic fluid of all the cases showed no contrast. But 3 cases have the cystic wall calcification, the walls of 2 cases have enhancement, but the other 3 have no enhancement. All of the four cases with MR examination appeared long T1, long T2 abnormal intensity with short T1, short T2 septation compared with fluid signal. Conclusion： CT and MR/ are the accurate methods to locate and diagnose the adrenal cysts.
