La stéatose focale du segment IV hépatique peut ressembler à une lésion de carcinose péritonéale, au scanner et en IRM

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 pre-operative 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.
