Axial T1-weighted (A), fat-suppressed T2-weighted (B), axial (C), and sagittal (D) contrast-enhanced magnetic resonance images demonstrate a solid and cystic distal fibular lesion with cortical breakthrough, an extra-osseous mass, and surrounding inflammatory changes. Note T2-weighted hyperintense nonenhancing cystic areas, and moderately T2-weighted hyperintense enhancing solid nodular elements.
