Long-term outcome of giant cell tumor of bone involving sacroiliac joint treated with selective arterial embolization and curettage: a case report and literature review

BACKGROUND Giant cell tumor of the sacrum, especially involving the sacroiliac joint, is rare, but is particularly challenging to treat. The long term outcome of a patient was studied with giant cell tumor involving the sacroiliac joint treated with selective arterial embolization and curretage. METHOD One patient with giant cell tumor involving the sacroiliac joint was treated with selective arterial embolization and curettage in our hospital in October 2002. The curettage and bone grafting was done after two times of selective arterial embolization;1600 ml of blood were transfused and no complications developed during the operation. RESULTS At the final follow-up of 9 years after the operation, no local recurrence and metastasis developed and she retained normal activity in daily life. CONCLUSION We think it is an optimal treatment for giant cell tumor involving the sacroiliac joint, with repeated selective arterial embolization and curettage, which has the advantage of less injury, less blood loss and fewer complications.
