A CT abdomen/pelvis without contrast revealed an interval increase in the size of hypoattenuating right adrenal mass measuring 9.7 x 7.7 x 6.1 cm compared with 8.2 x 6.9 x 6.4 cm 6 months prior (Figure 1).
(A) Normal adrenal gland cortex (*) and myelolipoma characterized by
hematopoietic elements and adipose tissue (hematoxylin and eosin [H&E],
100x). (B) Myelolipoma hematopoietic elements and adipose tissue reminiscent
of normal bone marrow (H&E, 200x).

Pathology of the adrenal tumor demonstrated an 11.5 x 9.5 x 7.5 cm well-circumscribed, partially encapsulated proliferation of mature adipose tissue with admixed hemopoietic elements consistent with myelolipoma weighing 29.3 g (Figure 2).
