The latter showed a left adrenal lesion measuring 62 x 45 mm, solid-necrotic with a spontaneous density of 40UH, 84% absolute washout, and 37% relative washout (Figure 1A-1B).
Voluminous mass in the external part of the left adrenal gland, well limited, with regular contours (orange circle), encapsulated, described in intermediate T2 signal with areas in marked T2 hypersignal (orange arrow), restrictive in diffusion (red circle), not showing any signal decrease in the OP sequences (red arrow)

III enhancement curve, outlining areas of necrosis (Figures 2-3). It measured 59 x 43 mm, responsible for the reflow of the external splenic vein, without any signs of kidney or pancreas invasion.
Heterogeneous and progressive enhancement following a type III enhancement curve, (non-subtracted series B' / subtracted series B''), delimiting areas of necrosis (red arrow).
