Her computerised tomography (CT) scan of the chest and abdomen showed an enhancing 8.7x8.6 cm left supra-renal mass with areas of heterogeneity (Fig. 1).

We subsequently performed a whole-body 18flouro deoxy glucose (FDG) PET/CT, which showed intense increased uptake of 18FDG within the mass with a standardised uptake value (SUVmax) of 25, suggesting malignancy (Fig. 2).
A 24-h urinary steroid profile: (a) pre-adrenalectomy compared with (b) the normal control. The profile is dominated by the Delta5 steroids, in particular pregnenetriol (5PT), DHEA (DHA) and 5PD, and the glucocorticoid precursor, THS. Peaks A, S and CB are internal standards.
