Bone hemangiomas are benign and infrequent lesions. At Tc-99m bone scintigraphy they show variable degrees of radiotracer uptake and even absence of it. At fluordeoxy-glucose (FDG) Positron Emission Tomography-Computed Tomography (PET/CT), hemangioma is one of the causes of "cold" vertebrae, apart from postexternal radiotherapy. We present a woman diagnosed of breast carcinoma, with a photopenic defect at a thoracic vertebrae at Tc-99m bone scan. In order to rule out bone lytic metastasis, a FDG PET/CT was performed showing a "cold" vertebrae too. Findings were highly suggestive of vertebral hemangioma, that was confirmed by magnetic resonance imaging.
骨血管瘤是一种良性且罕见的病变。在锝-99m骨闪烁扫描中,它们显示出不同程度的放射性示踪剂摄取,甚至无摄取。在氟脱氧葡萄糖(FDG)正电子发射断层扫描-计算机断层扫描(PET/CT)中,血管瘤是“冷”椎骨的病因之一,外部放疗后除外。我们报告一名被诊断为乳腺癌的女性,在锝-99m骨扫描中胸椎有放射性缺损。为排除溶骨性骨转移,进行了FDG PET/CT检查,结果也显示为“冷”椎骨。这些发现高度提示为椎体血管瘤,磁共振成像证实了这一点。
