20 year-old male with history of osteosarcoma. There are postsurgical changes from left proximal fibular resection with adjacent scarring and mildly increased T2 signal within the surgical bed and soft tissues likely representing edema. There are foci of signal void artifact within the lateral proximal tibia and soft tissues of the surgical bed related to orthopedic hardware and clips. On postcontrast imaging there is no evidence of abnormal enhancing mass to suggest residual tumor or tumor recurrence. There is mild edema-like signal about the medial femoral condyle which is nonspecific. There are periosteal changes at the resection margin of the fibular as well as increased marrow signal which is favored to be postoperative in etiology. There is no lymphadenopathy. The remainder of the visualized tibia, fibula, and femur are unremarkable.
Postsurgical changes without definitive evidence of residual tumor or tumor recurrence.
