Abstract:
Objective To explore the computed tomography (CT)manifestations of adrenocortical oncocytoma (ACO)for better understanding the disease and improving its diagnosis accuracy.Methods The CT manifestations of 9 cases with adrenocortical onco-cytomas confirmed by surgery were retrospectively reviewed and compared with pathological results.Results Five of cases were lo-cated in left side while 4 cases were in right side.Well defined and round or oval border could be found in all the cases.Of all the ca-ses,3 cases were solid lesions with equal density,< 3 cm in diameter,and mild consistent intensification after enhancement.Cystic lesion was detectd in 6 cases with > 3 cm in diameter.The mixed cystic and solid components with polycystic changes could be found on CT image,and remarkable intensification on solid lesion while no intensification on cystic lesion after the enhancement. Moreover,patchy or cotton-like shape could be found on solid lesion in 4 cases and 1 case with island like intensification;reticular pattern could be found in the central of lesion in 3 cases and 1 case with stellate shape.Pathological observation showed that the on-cotytomas were comprised of cells with abundant eosinophilic cytoplasm and necrotic and fibrous capsule without pathological mitosis could be found in some of lesion.Conclusion The characteristic CT features of adrenocortical oncotytoma has a worse specificity,its diagnosis was dependent on pathologic examination.
