Extract

Osteoid osteomas are rare, benign tumors. They are differentiated from osteoblastomas by their size. McLeod et al. defined lesions with a diameter of =1.5 cm as osteoid osteomas and those with a diameter of >1.5 cm as osteoblastomas1. Approximately 20% of osteoid osteomas occur in the spine, and most involve the posterior elements2,3. Ten percent of those in the spine occur in the vertebral body4. The lumbar spine is the most commonly involved segment3,4. The rate of associated compensatory scoliosis has been reported to be as high as 74%; Heiman et al. reported that seventeen (74%) of twenty-three patients with osteoid osteomas or osteoblastomas had a spinal deformity4. The tumor typically is located at or near the concave apex of the curve5,6. If the fourth or fifth lumbar vertebra is involved, the apex is typically cephalad to the lesion and pelvic obliquity is present5. Asymmetric pain-provoked muscle spasm on the side of the lesion is thought to be the cause of the scoliosis6. Ransford et al. postulated that the concave-side muscle spasms, if present for long enough, eventually will cause asymmetric growth inhibition of the vertebral epiphysis, leading to a rotational deformity and making the curve more structural7.
