Purpose: To evaluate CT diagnosis of the Large adrenal cysts. Materials and Methods: The CT features of 14 cases with the large adrenal cysts confired by operation and pathology,were analyzed retrospectively. Results: On axial CT scans,8 adrenal cysts appeared as a round and 6 oval shaped cystic masses. The most diameters of the cysts were between 4cm to 16cm,average 8 cm. All 14 adrenal cysts had homogeneous hypodensity,with a range of CT value 2～18Hu. Eight cystic wall were smooth,6 slightly lobulated. On post-contrast CT scans,there were no enhancement in all 14 cases. There were preoperative correct diagnosis in 12 cases and suspected diagnosis in 2 cases.
