Case 173: Steatosis / Steatohepatitis
57 year old woman, breast cancer surveillance.
CT: Focal fatty sparing and focal fat
CT shows incidental finding of focal area of fat sparing in typical location in segment 4, most likely related to small adjacent vessel (third inflow). Note also incidental focus of increased fatty transformation more anteriorly along the falciform ligament (first image), which could also represent an area of non-portal blood supply only rather than focal steatosis. Unenhanced image would be necessary to make that distinction.
