Radiologic and histologic findings. (A) Axial CT view of the upper abdomen after intravenous contrast injection and oral contrast administration: Large solid mass in the right suprarenal region with faint central calcification and central stellar hypodensity. Small arrows indicate the anterior border of this mass. The smaller more homogeneous solid lesion in the left suprarenal region is indicated by one large arrow. The right-sided lesion displaces the inferior vena cava anteriorly and medially, and there is visibility of an intracaval defect corresponding to a clot. (B) H&E stain showing elongated spindle cells arranged in a storiform pattern admixed with scattered chronic inflammatory cells (original magnification ×400). The images were captured digitally through a Nikion Eclipse i80 microscope (Nikon) with a 40×/0.75 objective at room temperature without flourochromes. The camera was a Pixelink PL-SW Microscopy (Canimpex Enterprise Ltd) with acquisition software of Pixelink Capture SE Version 4 software for Windows XP (Canimpex Enterprise Ltd). No subsequent image reprocessing occurred.
