myelolipoma

The wider application of increasingly sensitive ultrasonography and CT scanning has created a new problem for clinical management: the incidental discovery of asymptomatic adrenal lesions. These lesions, also called "incidentalomas" may be due to a large variety of etiologies, and although most of them prove to be benign cortical adenomas, diagnostic confirmation is frequently impossible preoperatively. For this reason, a general approach, based on the relative prevalence of benign and malignant, clinically silent adrenal masses, has been defined. This same approach is usually needed in the case of myelolipoma, a rare form of benign and silent adrenal neoplasms, containing hematopoietic and fatty elements. Actually, computed tomographic aspect of such tumors is very evocative but not pathognomonic, so it doesn't eliminate the possibility of malignant lesions, especially in the presence of heterogeneities. Because of these limitations and awaiting the development of more specific diagnostic procedures, it seems cautious to approach these tumors like incidentalomas in general.PublishedN/
