Objective To study the clinical and pathological features of adrenal myelolipoma. Methods The clinical manifestration,experimental and imaging data of 6 patients with adrenal myelolipoma were retrospectively analyzed. Results The disease manifested nonspecific symptoms and signs,including faint lumber,flank or bulk pain.The diagnosis of adrenal myelolipoma depends on B ultrosound scan,CT and MRI,revealing a fatty mass with various other densities such as soft tissue,intratumoural haemorrhage,calcification and residual adrenal cortex.Tumor excision and adrenalectomy were performed in all patients.The pathological examination showed that the tumor consists of mature fat cells and hematopoietic elements.The patients have been asymptomatic on following up for 0.5～7 years and there is no recurrence of tumor. Conclusions CT and MRI images features are helpful for the pre operative diagnosis of adrenal myelolipoma.Pathologically,it is characterized by a mixture of mature fat and hematopoietic elements.
