A 47-year-old male with hypertension presented with epigastric pain. He did not have gallstones and rarely drank alcohol. Physical examination revealed tachycardia and epigastric tenderness. Abdominal CT scan showed pancreatic stranding. Serum triglycerides were 3568 mg/dl (range 0–150 mg/dl). He was diagnosed with hypertriglyceridemia-induced pancreatitis (HTGP).
