In the last 30 years the development and widespread use of modern imaging techniques has caused a 20-time increase in the diagnosis of adrenal incidentaloma (AI).

Abstract
In the last 30 years the development and widespread use of modern imaging techniques has caused a 20-time increase in the diagnosis of adrenal incidentaloma (AI). Among AIs myelolipoma (ML) is reported with a frequency up to 10%. In the literature 8 patients with adrenal masses in thalassaemia or chronic haemolytic anaemia have been reported: five cases were shown to have extramedullary haematopoiesis (EH) and 3 ML. We describe here a case of an adult male affected by beta thalassaemia intermedia and large bilateral lipomatous adrenal masses. The patient was referred to our ward at the age of 55 and underwent hormonal testing, MRI, and SPECT/CT scans. Adrenal masses were hormonally inactive, and fat-containing on MRI and CT scans. SPECT/CT examination with 99mTccolloid demonstrated the presence of marrow tissue. ML and EH are the only two tumours with marrow tissue among lipomatous adrenal masses. In our patient a brown nodular mass was resected and histologically classified as ML. In benign adrenal masses, radiological follow-up is indicated; in case of large bilateral masses adrenal function tests are suggested periodically in order to detect possible adrenal hypofunction.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
