FIG 3. 80-year-old woman with primary pharyngeal cancer. A normal-sized, fat-replaced left jugulogastric lymph node was interpreted as abnormal because of inhomogeneous signal intensity.

A, Axial nonenhanced T1-weighted (600/17/1 [repetition time/echo time/excitations]) MR image shows intrinsic high signal intensity in the lymph node (arrows) consistent with fat.

B, Axial fat-suppressed T2-weighted (4000/80/1) MR image obtained at the same level as that in A shows hypointensity in the hilum of this node (arrow) consistent with suppressed fat.
