Figure 2. Gadolinium-enhanced abdominal MRI with non-hepatic-specific contrast.

(A) T2WI sequence axial plane with markedly hyperintense signal of the right adrenal mass (light bulb sign) and (B) T1WI hypointensity signal. (C) T1FS post-contrast arterial phase axial imaging with hypervascular behavior. (D) Prominent vascular structures were present. (E) Dual-echo in-phase and (F) opposed-phase T1-weighted imaging showing loss of signal of the lesion inferior to the right renal pole.

MRI: magnetic resonance imaging; T1WI: T1-weighted imaging; T1FS: T1 fat suppression; T2WI: T2-weighted imaging.
