Pancreatic panniculitis is an inflammation and necrosis of fat at distant foci in patients with pancreatic disorders, most frequently, pancreatitis and pancreatic carcinoma. Clinically, pancreatic panniculitis is manifested by painless or painful subcutaneous nodules on the legs, buttocks, or trunk. The usual sites are the distal parts of the lower extremities. To the best of our knowledge, there have not been many reports for the radiologic findings of pancreatic panniculitis. In this article, we report a case of pancreatic panniculitis, including radiologic findings of CT and ultrasonography. The patient was presented with painful subcutaneous nodules on the trunk, and had underlying acute pancreatitis and hemorrhagic pseudocysts.
