Our case report describes acute hepatic decompensation from an occult pancreatic malignancy. A 64-year-old man presented with abdominal distension for 2 weeks associated with decreased appetite and a weight loss of 13.6 kg, over the past 8 months. Significant admission labs were serum creatinine: 6.15 mg/dL, serum bilirubin: 27 mg/dL, aspartate aminotransferase (AST): 316 u/L, alanine aminotransferase (ALT): 198 u/L and serum alkaline phosphatase: 2121 u/L. He was admitted to the medical intensive care unit and was started on dialysis for acute renal failure. MRI of the abdomen showed multiple masses in the liver concerning for metastatic disease, cystic lesions in the pancreatic body and ascites. He underwent paracentesis and ascitic fluid analysis was positive for adenocarcinoma. CA 19-9 was 17 828 u/mL. The patient’s condition gradually deteriorated, and he died of cardiac arrest.
