Unusual Patterns of Hepatic Steatosis Caused by the Local Effect of Insulin Revealed on Chemical Shift MR Imaging

OBJECTIVE: We reveal the chemical shift MR findings of unusual patterns of hepatic steatosis caused by the local effect of insulin. CONCLUSION: Unusual patterns of hepatic steatosis can be seen on MR imaging. Such patterns result from localized high concentrations of insulin. A rim of hepatic steatosis surrounding insulinoma metastases and a subcapsular distribution of hepatic steatosis in patients with diabetes treated with peritoneal dialysis are two such patterns that can be revealed on chemical shift imaging.
