case_images: (a) 2 months later, the lytic lesion has rapidly progressed and destroyed the external cortical bone of the proximal peroneal head. (b) Initial right knee radiography where we notice a small bony spicule at the proximal fibula head.

case_images: Knee radiography showed a lytic lesion with ill-defined margin in the proximal right fibula measuring 1 x 1 cm and breaking through the outer cortex (Figure 1(a)). We reserved the differential diagnosis of focal osteomyelitis versus a tumoral process since the radiography showed that progressive lesion (Figure 1(b)).
case_images: Sagittal MRI section of the lower limbs. We notice the presence of a T2 hypersignal at the level of the proximal right fibular head, with erosion of the lateral cortical bone and extension into adjacent soft tissues in the form of a collection.

case_images: T2 images of the proximal right fibular head with breakage through the outer cortical bone and an abscess extension in the surrounding soft tissues. This excluded the tumoral process as a causal agent and oriented us to a focal osteomyelitis with local infiltration of peripheral tissues (Figure 2).
