Pancreatitis and renal infarction on CT scan of abdomen/pelvis with IV contrast. Computed Tomography (CT) showing severe left hydronephrosis without discrete ureteral calculus. There is also left renal cortical hypo-enhancement, which is suggestive of pyelonephritis and acute pancreatitis (vertical red arrow) but no pancreatic necrosis or peri-pancreatic fluid. Bilateral kidneys were significant for renal infarctions (horizontal arrow).
