The case is a 73-year-old man. We carried out the procedure pancreatoduodenectomy for distal cholangiocarcinoma of T2N0M0 Stage IB. After the operation, a follow-up CT scan of the pancreatic remnant was preformed. A enriching ingredient was found in the pancreatic remnant.
Blood tests showed a rise (773.8U/ml) of CA19-9 confirming MRI result. Thus, an endoscopic ultrasound (EUS) was preformed for the purpose of diagnosis purpose.
An endoscopic ultrasound fine-needle aspiration (EUS-FNA) was carried out for a low echo lesion of 12.1mm*7.2mm on the body of the pancreas, and the diagnoses of xanthogranuloma inflammatory tumor (xanthogranulomatous pancreatitis) in the pancreas was made. We continued with the follow-ups sessions. The tumor disappeared in the CT scan and the tumor marker improved afterwards, too. Diagnosis for xanthogranulomatous inflammatory tumor is easily confused with gallbladder tumors, so an operation is usually done to confirm the diagnosis. However, we were able to diagnose xanthogranuloma inflammatory tumor (xanthogranulomatous pancreatitis) in the pancreas by EUS-FNA. We report this case to show that it is possible to avoid unnecessary operations by observing the image changes over time.
