HOSPITAL COURSE SUMMARY:

Patient Case Report: A 70-year-old man presented with a hypervascular, 7 cm pancreatic body mass that involved the splenic vein on routine surveillance CT scan. He had a history of RCC and underwent a left nephrectomy and adrenalectomy in 2002, as well as pancreaticoduodenectomy for adenocarcinoma of the ampulla of Vater in 2003. He never received chemotherapy for either the RCC or PDA.

Hospital Course:
- Completion pancreatectomy and splenectomy were performed to resect the newly discovered pancreatic lesion.
- Due to the patient's apancreatic status, he received diabetic teaching and was started on parenteral insulin. He was referred to an endocrinologist for follow-up.
- He received appropriate vaccinations for encapsulated organisms due to his splenectomy and asplenic status.
- Repeat CT scans were scheduled at 4 months postoperatively, and every 3 months thereafter provided no active disease progression.
- The patient followed up with the medical oncologist who advised against adjuvant chemotherapy or radiation therapy, opting for imaging surveillance for now despite the one positive lymph node.
