title: CT of adrenal myelolipoma: report of 7 cases.
abstract: Seven cases of adrenal myelolipoma are reported. The series consisted of 1 male and 6 females, ranging in age from 30 to 76 years. In 5 cases the tumor originated from the right adrenal, in 1 case from the left adrenal and the remaining patients had bilateral tumors. Symptoms related to the mass were present in 4 cases but in contrast to other reports no hematuria was found in this series. All the tumors laid behind the angles formed by the lateral and medial limbs of adrenals. Fat density dominated in 6 tumors and soft tissue density dominated in 2. Calcification spots were revealed in 3 tumors. In two predominantly soft tissue density tumors the complete peripheral rims were revealed, while in the remaining 6 tumors the peripheral rims were considered incomplete based on the CT images. In 3 cases large amounts of fat were found surrounding the normal contralateral adrenal. The cause is still open to further investigation. Spiral CT with thin collimation provided detailed morphological information for adrenal myelolipoma.
