T2 weighted image demonstrates chemical shift artifact around the lipoma in the frequency encoding direction (anteroposterior). Note how there is signal loss anteriorly (black arrows) and hyperintensity posteriorly (white arrows). This is the result of inaccurate spatial encoding, resulting in the lipoma being incorrectly placed posterior to its actual location.
It should be noted that this appearance is not seen on gradient-echo sequences, where signal drops out will be in all directions.
