MRI was performed before chemotherapy treatment. Axial T2-weighted image (A) reveals a large left-sided adrenal mass (*) that extends anteriorly to the superior mesenteric artery (arrow). Axial (B) postcontrast subtraction MR images display a homogeneous contrast enhancement of the mass (*). On diffusion-weighted images, (C) the lesion showed restricted diffusion. On coronal T2-weighted images (D, E) and postcontrast subtraction MR (F) images, the mass enhances and displaces the left kidney inferiorly, the spleen laterally, and extends to the midline, encasing the celiac trunk and splenic vein (arrows).

Based on MRI features, adrenal adenoma and adrenal hemorrhage were excluded (Figure 1).
MRI after two courses of chemotherapy: Axial T2- weighted image (A), axial T1-weighted image (B), coronal T2-weighted image (C), and coronal postcontrast T1-weighted image (D) demonstrate a decrease in the size of mass (*).

After two courses of chemotherapy, MRI displayed regression of the mass (>50-60% of initial size) and a decrease in the number of enlarged lymph nodes (Figure 2).
