J Bone Joint Surg Br. 1984 Jan;66(1):16-20. The behaviour pattern of the scoliosis associated with osteoid osteoma or osteoblastoma of the spine.Ransford AO, Pozo JL, Hutton PA, Kirwan EO.
The behaviour pattern of the scoliosis associated with osteoid osteoma or osteoblastoma of the spine is described. In patients presenting with symptoms at or around skeletal maturity, the scoliosis is postural. Excision of the lesion ensures complete resolution of the curve. In the growing child, however, an initial postural scoliosis may develop vertebral rotation with structural characteristics. The magnitude of the curve and the associated vertebral rotation is dependent on the time interval between the onset of symptoms and the surgical treatment. Although removal of the lesion usually results in regression of the curve, a prolonged delay in treatment may result in a progressive structural scoliosis. A possible mechanism for the behaviour of the scoliosis is discussed.

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, making the relationship less clear.

Orthopaedics:
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 in diameter.

Discussion: - unusual benign osseous tumor; - it resembles osteoid osteoma in some respects buts is larger ( >2 cm); - unlike osteoid osteoma: - occurs in older adolescents and young adults; - osteoblastoma usually does not cause localized night pain, and when pain occurs, pain is usually not relieved by ASA; - intense bony reaction that is seen w/ osteoid osteoma, does not occur with osteoblastoma; - osteoblastoma more often located in the posterior elements of vertebra; - osteoblastoma will not resolve spontaneously; - sites of involvement: spine, femur, bone of the foot; - an associated soft tissue mass may be seen in about 25% of patients; - in rare cases, malignant transformation is possible
