Spinal Hemangioma An Unusual Photopentic Presentation on Bone Scan

摘要

A vertebral hemangioma is a slow-growing, benign tumor most frequently seen in the lower thoracic and upper lumbar vertebrae. The characteristics of this lesion have been described for the various imaging modalities.3,7,9Although hemangiomas usually produce increased activity on bone scans, we present an unusual case of a solitary vertebral hemangioma that produced a photopeni leision. This unexpected finding prompted further evaluation with radiographic and magnetic resonance imaging studies, which showed the lesion to have the typical findings of a hemangioma. A possible explanation is discussed.
