Answer. D. Chemotherapy is the treatment of choice
Given image is of Giant cell tumor
- Giant cell tumors of bone, also known as osteoclastomas, are relatively common bone tumors and are usually benign.
- They typically arise from the metaphysis of long bones, extend into the epiphysis adjacent to the joint surface, and have a narrow zone of transition.
Classic appearance
There are four characteristic radiographic features when a giant cell tumor is located in a long bone:
- occurs only with a closed growth plate
- abuts articular surface: 84-99% come within 1 cm of the articular surface 1
- well-defined with non-sclerotic margin(though
- eccentric: if large this may be difficult to assess
Treatment
-
Classically, treatment is with curettage and packing with bone chips or polymethylmethacrylate (PMMA).
