Typical imaging manifestations of patients with local recurrence treated with extended curettage. (a) Anteroposterior and lateral radiographs showed that the proximal and lateral parts of the right tibia had obvious osteolytic foci at the original site. (b) Computed tomography (CT) scan confirmed low-density osteolytic changes in the original site. (c) Extended curettage, cement filling, and subchondral bone grafting were performed after relapse of GCTB was confirmed by biopsy (white arrow points to the lesion).
