Radiology:Osteoblastoma is an uncommon primary neoplasm of the bone. It has clinical and histologic manifestations similar to those of osteoid osteoma; therefore, some consider the two lesions to be variants of the same disease, with osteoblastoma representing a giant osteoid osteoma. However, an aggressive type of osteoblastoma has been recognized,...

Osteoblastoma is a rare primary neoplasm of bone, categorized as a benign bone tumor. However, an aggressive type of osteoblastoma has been described that has characteristics similar to osteosarcoma. Osteoblastoma is closely related to osteoid osteoma. It differs from osteoid osteoma in its ability to grow larger than 2 cm...
