What is an osteoma of the spine?
Osteoma = a type of tumor that develops in bones. Osteoid osteomas are small, benign bone tumors. Osteoid osteomas most commonly occur in the legs, hands, fingers, and spine. At the Spine Hospital at the Neurological Institute of New York, we specialize in osteoid osteomas of the spine.
Is Osteoblastoma curable?
Vertebral osteoblastoma is a rare benign tumor primarily of the posterior elements. It is curable by resection and has a good prognosis.
Can an osteoid osteoma come back?
It usually appears in teenagers and young adults. Its cause is unknown. The most common treatment uses radio frequencies to heat and kill cancerous cells. Treatments are usually successful, though the tumors can come back.
Can osteoid osteoma turn cancerous?
Osteoid osteoma is a benign bone-forming tumor that does not turn malignant.
Is osteoid osteoma hereditary?
Familial occurrence of osteoid osteoma is an exceedingly rare event.
How common is osteoid osteoma?
Osteoid osteoma accounts for around 5% of all bone tumors and 11% of benign bone tumors. Osteoid osteoma is the third most common biopsy analyzed benign bone tumor after osteochondroma and nonossifying fibroma. Two to 3% of excised primary bone tumors are osteoid osteomas.
Does osteoblastoma metastasize?
Benign tumors do not spread to various sites or organs. However, an aggressive type of osteoblastoma has been identified in very rare occasions that have led to metastasis, death, and mimicked osteosarcoma.
Are there any osteomas or osteoblastomas in the spine?
Object: Osteoid osteomas and osteoblastomas are rare primary bone tumors that usually do not arise in the spine. In this report the authors analyze 16 cases of osteoid osteoma or osteoblastoma of the spine that were surgically treated over a 27-year period.
How big is the rim of an osteoblastoma?
None of the patients with osteoid osteoma had neurological deficits. The diameters of osteoblastomas were 3 to 8 cm (mean 4 cm), and those of osteoid osteomas were 1.5 to 2 cm (mean 1.7 cm). Although the peritumoral bone was normal in patients with osteoblastoma, a sclerotic rim was observed in all patients with osteoid osteoma.
Is the peritumoral bone normal in Osteoblastoma?
Although the peritumoral bone was normal in patients with osteoblastoma, a sclerotic rim was observed in all patients with osteoid osteoma. All patients were treated with resection; tumor excision was complete in 15 cases. Follow-up periods ranged from 2 months to 13 years (mean 36 months).
Are there neurological deficits in patients with osteoblastoma?
Among 11 patients with osteoblastoma, six (two with paraparesis, four with monoparesis) had neurological deficits caused by extradural compression. None of the patients with osteoid osteoma had neurological deficits. The diameters of osteoblastomas were 3 to 8 cm (mean 4 cm), and those of osteoid osteomas were 1.5 to 2 cm (mean 1.7 cm).
