Osteoid osteoma of the vertebral body: an unusual localization

As a benign skeletal neoplasm the osteoid osteoma that contains osteoblasts producing osteoid and woven bone, may be seen in various sites of the body. It is mostly seen in the long bones of the extremities and posterior elements of the vertebrae. Involvement of the vertebral body is not common. It may be confused with osteoblastoma; the only criteria in distinction the both condition is the lesion size. Here, we report a case of osteoid osteoma at the body of T8 vertebra, with its imaging findings.
