| 摘 要： | 目的 探讨肾上腺囊肿的CT、MRI表现,以提高诊断的准确性.方法 回顾性分析手术病理证实的10例肾上腺囊肿的CT、MRI表现.结果 10例肾上腺囊肿,6例行CT检查：囊肿壁薄、均匀,1例囊壁有钙化,1例囊内可见分隔,分隔上见点状钙化灶.平扫囊内密度均匀,CT值约为15 HU～30 HU,增强扫描囊内均未见强化,1例囊壁轻度强化,5例囊壁及分隔均未见强化.4例行MRI检查：囊内均呈长T1、长T2信号,囊壁呈长T1、略长T2信号,增强扫描囊内和囊壁均未见明显强化.结论 肾上腺囊肿的CT、MRI表现具有特征性,有助于临床明确诊断.

| Abstract: | Objective To evaluate CT and MRI findings of the adrenal cyst in order to improve diagnostic accuracy. Methods The CT or MRI studies of 10 histologically-proven adrenal cysts were retrospectively analyzed. Results CT was performed in 6 cases and showed smooth thin cyst wall （6）, mural calcification （1）, septation with punctuate calcification （1）. The CT densities of cyst fluid were 15-30 Hounsfield units without contrast enhancement. The wall of 1 cyst enhanced slightly whereas the remaining 5 did not enhance with intravenous contrast. All 4 cysts on MRI were T1 hypointense and T2 hyperintense without contrast enhancement. Conclusion CT and MRI findings of adrenal cysts are characteristic and conducive to diagnosis. |
