骨岛又被称为骨斑或内生骨疣,是位于松质骨内大小不一的致密骨,好发于骨盆、股骨及其他长骨,一般是由软骨内骨化过程中的异常引起[1]。常见的骨岛多较小,大部分患者无临床症状,骨扫描通常未见代谢增高[2],临床上显示为代谢增高的骨岛较少见[3-6],易造成误诊。我们分析了1例最终经组织病理学检查结果证实的99Tcm-MDP SPECT/CT全身骨显像代谢增高的骨岛患者的影像表现特点及鉴别诊断过程,以提高影像医师对该病的认识。
99Tcm-MDP SPECT/CT代谢增高骨岛一例
An increased metabolic bone island with 99Tcm-MDP SPECT/CT imaging: a case report

摘要: 骨岛是一种良性骨病变,大多数的骨岛较小,临床上骨显像显示代谢增高的骨岛较少见。笔者报道了1例99Tcm-亚甲基二膦酸盐(MDP) SPECT/CT代谢增高的骨岛患者,分别从临床症状、影像学表现及组织病理学检查结果等方面介绍并分析了该病的特点,并通过文献复习加深了对骨岛的认识,旨在提高影像医师对该病的认识,避免误诊。Abstract: Bone islands are completely benign bone lesions, most of the bone islands are small. In clinical, bone imaging shows that bone island with increased metabolism is rare. The author reported a case of bone island with 99Tcm-methylenediphosphonate(MDP) SPECT/CT showing increased metabolism. The characteristics of the disease were analyzed including the clinical symptoms, imaging manifestations, pathological diagnosis and histopathology, and were deepened the understanding through literature review. The aim of this study is to improve the awareness of the disease and to avoid misdiagnosis for imaging physicians.
