Figure 12: Axial postcontrast computed tomography scan of the abdomen demonstrated a large hypovascular mass (extramedullary plasmacytoma; open red arrows) at the head of the pancreas. There was a marked circumferential narrowing of the second part of the duodenum due to infiltration of the plasmacytoma into the second part of the duodenum. The hyperdense linear structure at the center of the plasmacytoma (open yellow and green arrows) represented residual lumen of the second part of the duodenum
