[Myelolipoma of the adrenals]

A 47-year-old man reported increasing feeling of fullness in the upper abdomen and pain in both flanks, radiating to both groins. Physical examination did not reveal any abnormalities. Biochemical tests demonstrated hypertriglyceridaemia and hypercholesteremia. Urography, abdominal ultrasound, computed and magnetic resonance tomography revealed a large, fat-containing tumour of the right adrenal. At operation a soft, somewhat elastic adrenal tumour, about 10 cm in diameter, was removed. Histologically it proved to be a myelolipoma. The correct preoperative diagnosis of such a tumour is possible in about 90% of cases.
