case_images: An abdominal magnetic resonance was ordered and showed an isointense smoothly marginated 4 cm mass in T1 (Fig. 1) and a signal intensity similar to the normal in T2 (Fig. 2).
case_images: Intraoperative aspect. White arrow: Castleman tumor. Blue arrow: Pancreatic head. Green Arrow: Duodenum.

case_images: Homogenous enhancement, similar to the pancreas in T1 with contrast (Fig. 3). On exploration, we found an encapsulated mass bulging in the retroperitoneum at the pancreatic head (Fig. 3).
case_images: Macroscopic appearance. The tumor had smooth borders and was capsulated.

case_images: The mass was completely excised, while preserving its capsule (Fig. 4), a feature that would not be typical in an pancreatic malignancy.
case_images: Immunohistochemistry. On the left: Prominent vascular proliferation and hyalinization of the vessel walls. On the right: Negative BCL2.
