A typical endonchroma would typically be located in the metacarpals.
Did you see the density within the left distal fibular radiolucency?
This is a key to enchondroma type lesions. The sagittal MRI confirms posterior expansion with extension distally not appreciated on plain radiographs.
A low-grade chondrosarcoma may be a key differential consideration, however.
A soft-tissue mass, periosteal reaction, cortical disruption in the juxta-articular fibula, cortical thickening, and tumor size greater than 4.0 cm indicate chondrosarcoma over enchondroma of the fibula.1
