Abstract
Late recurrence (more than five years) of benign giant-cell tumor of bone is uncommon. Two patients were evaluated by angiography, including injection of vasoactive drugs, because of osteolytic lesions developing six and seven years after primary operation for benign giant-cell tumor. Angiography established a probable recurrence in both cases. Angiography also permitted accurate evaluation of tumor extension, facilitating pre-operative planning. Giant-cell tumors are predominantly hypervascular lesions. Angiographic evaluation is therefore recommended when a recurrent lesion is suspected.
