Figure 1.
The adrenal MRI findings of PAL. MRI of the abdomen was performed in Cases 1 (1A-1B), 3 (2A-2B) and 4 (3A-3B). T2-weighted imaging revealed that the intensity was almost the same as that of the renal parenchyma in one case (1A; arrows). Heterogeneous hyperintensity was observed in the other two cases (2A and 3A; arrows). Diffusion-weighted imaging (DWI) showed high intensity in all 3 cases (1B, 2B and 3B; arrows).
