Unicentric Castleman Disease Mimicking a Pancreatic Tumor: A Case Report

摘要


Castleman disease is a group of uncommon lymphoproliferative disorders. It is characterized by lymph node enlargement and may mimic various benign and malignant tumors in the neck, chest, abdomen, and pelvis. The most frequent appearance of abdominal or pelvic Castleman disease is a single, well-defined hypervascular enhancing mass with prominent feeding vessels on the surface. While smaller tumors (< 5 cm) display homogeneous enhancement, larger tumors (> 5 cm) show heterogeneous enhancement due to central necrosis and degeneration. We report a case of Castleman disease mimicking a pancreatic tumor that received surgical resection to make the final diagnosis.
