T1 weighting (T1W) demonstrated a lesion with peripheral high signal (Figure 1).
T1-weighted coronal spin-echo pulse sequence. Peripheral high signal is seen within the entire lesion.

T2-weighted images revealed marked signal drop out centrally due to magnetic susceptibility artefact from altered blood products, usually haemosiderin (Figure 2). The mass was shown to extend posteriorly as far as the medial cortex of the femur and medially to the femoral canal (Figure 3).
T2-weighted gradient-echo pulse sequence. Marked low signal is seen centrally secondary to magnetic susceptibility artefact from haemosiderin.
