Fig. 2. Photomicrograph of histopathologic specimen of percutaneous
core needle biopsy of subcapsular lesion in 41-year-old woman shows hepatic
fatty deposition within vacuolar spaces (white arrows). Black arrow
marks direction of liver capsule. Note increasing concentration of fat toward
capsular surface of liver. (H and E)

Fig. 5A. 61-year-old man with hepatic subcapsular steatosis. Axial
contrast-enhanced CT scan shows typical nodular form of hepatic subcapsular
steatosis (arrows). Peritoneal dialysis and therefore intraperitoneal
insulin were stopped immediately after scan because of peritonitis.

(arrows) are smaller, whereas others have resolved.
