Figure 1
Plain radiograph of the right leg and knee, anteroposterior and lateral views. Proximal tibiofibular joint shows erosion in juxta articular area in both tibia and fibula
Figure 2
Figure 2
(a) Axial T2-weighted image of proximal leg reveals a lobulated heterogeneous soft tissue mass of predominantly hypo intense signal intensity centered at proximal tibiofibular joint associated with articular erosions (arrows) and extension into muscles of both anterior and posterior compartments. (b) Sagittal T1-weighted image shows hypo intense mass in proximal leg with preserved knee joint. (c) Axial postgadolinium fat-suppressed T1-weighted image shows intense, heterogeneous predominantly peripheral enhancement of the mass. The mass encases anterior and posterior interosseous neurovascular bundles. (d) Coronal gradient echo image shows characteristic “blooming” phenomenon

Photomicrograph of the lesion (H and E, ×40) shows sheets of dyscohesive round to oval cells with extensive intracytoplasmic hemosiderin pigment (arrow) (a) and osteoclastic type of multinucleate giant cells (arrow) within the tumor (b)

Post 36 months follow-up magnetic resonance images showing mild dimensional disease reduction. (a) Axial T2-weighted image of proximal leg. (b) Sagittal T1-weighted image shows hypo intense mass in proximal leg with preserved knee joint. (c) Axial postgadolinium fat suppressed T1-weighted image. (d) Coronal gradient echo image
