  		Fig. 1E. —Focal rim of hepatic steatosis surrounding an insulinoma metastasis in 27-year-old man. Photomicrograph of histologic specimen shows three zones: insulinoma metastasis (T), adjacent focal hepatic steatosis without tumor infiltration (asterisk), and normal hepatic parenchyma (L).

  		Fig. 2B. —Subcapsular rim of hepatic steatosis in 35-year-old woman with diabetes mellitus who had insulin in peritoneal dialysate. Axial breath-hold spoiled in-phase gradient-echo MR image (TR/TE, 250/4.2) reveals irregular peripheral subcapsular rim of higher signal intensity relative to adjacent hepatic parenchyma (arrows).
