A small radiolucent rounded lesion with surrounding sclerosis of the medial femoral metaphysis.
Case Discussion
Radiographically, the hallmarks of a periosteal desmoid are its radiolucent saucer-shaped appearance, with sclerosis at the base eroding the cortex or producing cortical irregularity. Occasionally, it may simulate an aggressive and even malignant tumor.
