  Fig. 1. Precontrast axial (A) and coronal (B) CT showing heterogeneous right adrenal mass with high density medial component (arrow and mass effect on liver and right kidney).

• 

  Fig. 2. Precontrast axial (A), arterial phase (B), and late portal venous phase (C) CT showing mild enhancement of the medial component of the lesion.

• 

  Fig. 3. Axial MRI without contrast (A) and with contrast (B-D) showing Tl hyperintense component of the right adrenal lesion (white arrow) and progressive delayed enhancement of the medial component of the lesion.

• 

  Fig. 4. Axial MRI showing restricted diffusion within the medial aspect of the right adrenal lesion (arrows).
