A 39-year-old woman with focal fat infiltration of the pancreatic head. Axial portal venous phase CT image (a) show low-attenuation area (arrows) in the pancreatic head with a tongue-like extension just posterior to SMV. No mass effect or MPD dilatation. Note the normal attenuation parenchyma around the CBD. Axial chemical shift MR images show no abnormality at in-phase sequence (b) and drop of signal of the same area (arrows) at opposed phase sequence (c) consistent of microscopic fat in focal fat infiltration
