Figure 1
Conventional radiographs of the right leg, anteroposterior (A) and lateral (B) views. Cortical osteolytic lesions are visible in the distal third of the tibia and fibula (arrows). The lesions are well‑defined and associated with cortical thinning, without periosteal reaction or soft tissue involvement.
Figure 2
Axial CT image of the distal right leg showing well‑defined intracortical lucencies (arrows). Associated findings include cortical thinning and focal cortical defects, without evidence of periosteal reaction or extraosseous extension.
Figure 3
MRI of the distal right leg: T1‑weighted (A), T2 DIXON WATER (B), and post‑gadolinium contrast‑enhanced (C) sequences. Multiple intracortical lesions are centered in the cortex of the distal tibia, primarily involving the posterolateral and anterolateral aspects, with some extension into the anterior cortex (arrows). The lesions are hypointense on T1, hyperintense on T2 DIXON WATER, and show homogeneous enhancement after gadolinium administration. Additional small lesions are noted in the posteromedial cortex of the fibula.
