Gamma Knife treatment of recurrent CNS metastases of pancreatic origin: a case report and review of the literature

Brain metastases (BM) of pancreatic origin are extremely rare. We review the literature around BM of pancreatic origin and describe a 38-year-old woman who developed BM 10 months after pancreaticoduodenectomy for treatment of pancreatic adenocarcinoma.
