Lateral radiograph of the distal femur of a 17-year-old girl who felt an asymptomatic, firm lump in her popliteal space but had no disability. The radiograph revealed a 3 cm periosteal lesion on the back side of the distal femoral metaphysis with a sclerotic base and shell of reactive bone and calcification extending over the top of the lesion taking on the appearance of a large blister on the back side of the femur. There is evidence of matrix calcification in the central portion of the lesion suggesting a low-grade chondroid tumor.
