摘要: 目的:探讨脊柱恶性血管源性肿瘤的影像表现。方法:对9例经病理确诊的脊柱恶性血管源性肿瘤的CT和MRI表现进行回顾性分析并总结其影像特点。结果:9例中2例为血管肉瘤,7例为上皮样血管内皮瘤;5例病变位于颈椎,3例位于胸椎,1例位于腰椎;4例为单中心、2例为多中心病变,3例累及相邻椎体。CT 表现:9例均显示溶骨性骨破坏、周围骨皮质不完整,其中5例肿瘤内部可见残存骨嵴。MRI 表现:肿瘤于 T1 WI 呈低信号,于 T2 WI 呈混杂信号(3例)、中等信号(2例)或高信号(4例);增强扫描示肿瘤呈明显强化4例 ,呈中等强化 1例。结论:恶性血管源性肿瘤主要影像表现为单中心性或多中心溶骨性骨破坏、多位于颈胸椎,部分具有血管瘤的特点,容易导致脊柱压缩变形。 Objective:To explore the CT and MRI appearances of malignant vascular tumor of spine.Methods:CT and MRI findings of 9 cases with malignant vascular tumor of spine confirmed by operation and pathology were retrospectively analyzed and summarized.Results:There were two cases of angiosarcoma and seven cases of epithelioid hemangioendothelio-ma (EHE).The tumors of 5 cases located in cervical spine,3 cases in thoracic vertebra,and 1 case in lumbar spine;the tumors were local in 4 cases,multicentric in 2 cases,and involved the adjacent vertebral body in 3 cases.The main CT fin-dings:osteolytic bone destruction with incomplete bone cortex could be found in all cases,residual bone trabecula within the lesions could be seen in five cases.MRI findings:all tumors were hypo-intense on T1 WI;On T2 WI,3 cases showed heteroge-neous signal,2 cases iso-intense signal and 4 cases hyper-intense signal;four tumors showed obvious enhancement and one showed moderate enhancement on post-contrast images.Conclusion:Malignant vascular tumors of spine have some CT and MRI characteristics,including that the main location is cervical and thoracic spine,osteolytic bone destruction may be local or multicentric,some of them may have the characters of hemangioma and lead to spinal compression.
