[Myelolipoma of the adrenal gland]

The Authors report a case of adrenal myelolipoma, with clinical picture of abdominal painful syndrome. Myelolipoma is a mixed tumor of mature adipose tissue, intermingled with myeloid tissue. None of the many theories advanced up to day has succeeded in explaining how these myeloid and adipose inclusions occur in the adrenal gland. In the case reported tumor has a mass of huge size, displacing down the homolateral kidney. Useful diagnostic tools for this pathological condition are discussed. In the personal experience of the Authors urography, echotomography combined with C.T. allow a right preoperative diagnosis in a large amount of cases.
