Rare occurrence of pancreatic adenocarcinoma metastasis to the brain

A 56-year-old man with known pancreatic adenocarcinoma presented to the emergency department with facial twitching and a left-sided facial droop. Magnetic resonance imaging of the brain and subsequent biopsy revealed metastatic pancreatic adenocarcinoma with no other metastatic sites shown on computed tomography of the chest, abdomen, and pelvis. Following craniotomy and tumor resection, the patient has shown clinical improvement with no deleterious complications to date.
