Patient Data
Age: 45 years
Gender: Female
From the case:

ill-defined central lytic bone lesion involving the proximal fibular metaphysis and epiphysis
rings and arcs calcifications suggestive of a chondroid matrix
From the case:
Enchondroma
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/129719/annotated_viewer_json?lang=us"}
well-marginated central lesion involving the proximal fibular epiphysis.
It demonstrates an intermediate signal on T1 and a predominantly high signal on T2
internal foci of a low signal: 'rings and arcs' (chondroid matrix)
no "grow" through the cortex or gross bone destruction
no periosteal reaction or soft tissue mass
no bone marrow or soft tissue edema
Case Discussion
Features of a benign lesion with a cartilaginous matrix of the proximal fibular epiphysis, highly suggestive of an enchondroma.
