Ossifying fibroma of the lumbar spine: case report.

Ossifying fibroma of the vertebra is a very rare condition. We report a 16-year-old boy with ossifying fibroma of the third lumbar vertebra. Neurological and laboratory examinations demonstrated normal findings. Low-back pain, in the absence of radicular pain, was the presenting symptom. Plain radiography and computerized tomography scanning revealed an osteolytic lesion. The tumor in the third lumbar vertebra was curetted and filled with bone allograft. The histopathological diagnosis was consistent with ossifying fibroma. There was no postoperative complication. The case is the second to be reported. The clinical and radiological aspects of this rare tumor are discussed with the pertinent literature.
