Sagittal T1-weighted images show a lesion in the distal femur, that is isointense to fat marrow and contains bony inclusions. It has a sharp, signal-free border to the normal bone.
T2*-weighting shows bone susceptibility effects within and around the lesion. In Coronal STIR, most of the lesion's signal is suppressed, except for some hyperintense patches.
Transverse PD-FSE fat sat, the predominantly fatty components of the lesion appear dark. There is, however, some focal bright signal.
