Osteoblastomas are rare tumors accounting for approximately 1% of all primary bone tumors. We report a case of osteoblastoma of the mandible with high FDG uptake. Initially, this lesion was judged as an osteosarcoma. Osteoblastomas are benign slow-growing tumors. High-resolution thin-slice CT images of the lesion as part of the PET/CT study help to characterize its morphology and extension, thus facilitating biopsy planning and resection. Approximately 25% of osteoblastomas initially have the imaging appearance of a malignant tumor. In our case, complete resection of the lesion followed by reconstruction with a bone graft was performed.
成骨细胞瘤是一种罕见的肿瘤，约占所有原发性骨肿瘤的 1%。我们报告了一例下颌骨成骨细胞瘤，其摄取 FDG 较高。最初，该病变被判断为骨肉瘤。成骨细胞瘤是良性的、生长缓慢的肿瘤。作为 PET/CT 研究的一部分，病变的高分辨率薄层 CT 图像有助于其形态和扩展特征，从而有助于活检计划和切除。大约 25%的成骨细胞瘤最初具有恶性肿瘤的影像学表现。在我们的病例中，对病变进行了完全切除，然后用骨移植物进行重建。
