Title: Imaging features and differential diagnosis of malignant vascular tumor of spine
Abstract: Objective:To explore the CT and MRI appearances of malignant vascular tumor of spine.Methods:CT and MRI findings of 9cases 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 hemangioendothelioma(EHE).The tumors of 5cases located in cervical spine,3cases in thoracic vertebra,and 1case in lumbar spine;the tumors were local in 4cases,multicentric in 2cases,and involved the adjacent vertebral body in 3cases.The main CT findings: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 T1WI;On T2 WI,3cases showed heterogeneous signal,2cases iso-intense signal and 4cases 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.
