title: Focal fatty infiltration in Segment IV of the liver mimicking peritoneal carcinomatosis on CT and MR imaging.
abstract: Focal hepatic steatosis occurs often. If mistaken for liver metastasis, it can occasionally result in a decision against resection because of suspicion of locally advanced disease. Magnetic resonance imaging (MRI) often leads to the correct preoperative diagnosis, but if any doubt persists, surgery should not be precluded, even if the disease appears to be widespread, particularly since the classical age limitations for large magnitude operations have been steadily rolled back. The following 69-year-old patient, with peritoneal carcinomatosis from an appendiceal cancer and an atypical image in the liver corresponding to focal Segment IV steatosis, illustrates our message.
