Abstract: Objective To study the CT and MRI features of malignant adrenal tumors(MAT)for improving the understanding of the disease and imaging diagnosis.Methods CT and MRI findings were retrospectively reviewed in 1 7 patients with MAT proved by surgical pathology.CT scan was performed in 1 7 cases,and CT enhancement scan was performed in 14 cases;MRI scan was comple-ted in 3 cases,and MRI enhancement scan was performed in 2 cases;CT and MRI scans were examinated in 3 cases.Results Among 1 7 patients with MAT,there were 3 adrenocortical carcinomas,2 neuroblastomas,1 malignant pheochromocytoma,1 lymphoma,1 leiomyosarcoma,and 9 adrenal metastatic tumors.The CT and MRI characteristics in size,shape,boundary,density or signal,and en-hancement features,can discriminate MAT.Conclusion CT and MRI findings of some MAT have a certain characteristic;The ima-ging findings combined with clinical data are helpful in correctly making preoperative diagnosis.
