Figure 2. Magnetic resonance imaging: (A) coronal T2-weighted, and (B) fat-suppressed steady-state free precession images show the heterogeneous signal intensity of the right adrenal mass. (C) Axial diffusion-weighted image (DWI, b-value=800 s/mm2) shows some areas of restricted diffusion. (D) Axial in-phase and (E) opposed-phase gradient echo T1-weighted images also reveal a heterogeneous signal. A small area of signal drop in the opposed-phase image (arrow) may represent intracytoplasmic fat. (F) Non-contrast fat-suppressed gradient echo T1-weighted image reveals that the T1-hyperintense foci (arrow) are intratumoral hemorrhages. (G–I) Late arterial phase, portal venous phase, and 10-minute delayed, post-contrast, fat-suppressed T1-weighted images show peripheral early enhancement with progressive heterogeneous enhancement in later-phase images.
