【摘要】：目的部分肿瘤患者骨显像发现上颌骨额突单发放射性浓聚灶,诊断困难,并且相关研究较少。本文旨在探讨骨显像上颌骨额突放射性浓聚灶的性质及原因,以提高对该病变的认识。资料与方法选择上颌骨额突放射性浓聚但不伴其他骨转移瘤的21例患者,分析骨显像放射性浓聚灶的形态及分布,对比随访骨显像,观察病变有无变化,总结相应CT所见病变的部位、数目、大小、内部密度、边缘等形态学特点。结果 21例上颌骨额突浓聚灶累及单侧17例,双侧4例,1例伴其他颅骨病变。14例复查骨显像病变均未见变化,且未见新增病变。12例发现16个放射性浓聚灶,其中15个CT有异常表现,14个位于额突基底部鼻泪管周围。所有病变边界清楚,横截面最大径线平均7.1 mm。10个呈均匀磨玻璃密度,5个内部可见更低密度区。结论骨显像上颌骨额突浓聚灶倾向良性病变,CT提示骨纤维异常增生症样病变为导致异常浓聚的原因之一。
[Abstract]:Objective to investigate the characteristics and causes of the single radioactive foci in frontal process of maxilla by bone imaging in some patients with tumor, which is difficult to diagnose, and few related studies have been done in this paper. The purpose of this study was to investigate the characteristics and causes of the focal foci in the frontal process of maxillary bone on bone scintigraphy. Materials and methods 21 cases of maxillary frontal process with radioactive concentration but no other bone metastases were selected to analyze the shape and distribution of radioactive foci in bone scintigraphy, and to compare the follow up of bone scintigraphy. The location, number, size, internal density, edge and other morphological features of the lesions were summarized. Results 17 cases of unilateral lesions were involved in 21 cases of maxillary frontal process thickening foci. 1 case of bilateral bone lesions with other skull lesions. 14 cases of bone imaging lesions did not change, and no new lesions. 12 cases found 16 radioactive foci. Fifteen of them had abnormal CT findings, 14 of which were located around the nasolacrimal duct at the base of the frontal process. The mean maximum diameter of cross section was 7.1 mm.10, and the density of glass was even lower in 5 cases. Conclusion Bone imaging shows that the focus of frontal process of maxillary bone tends to be benign. Ct findings suggest that fibrous dysplasia of bone may lead to abnormal lesions. One of the reasons for concentration.
