股骨上皮样血管肉瘤^(99)Tc^(m)-MDP SPECT/CT显像一例

^(99)Tc^(m)-MDP SPECT/CT imaging in epithelioid angiosarcoma of the femur:a case report

骨上皮样血管肉瘤(EA)是来源于血管内皮细胞的高度恶性骨肿瘤,临床上较为罕见。笔者报道了1例经组织病理学检查证实的发生于股骨的EA病例,分别从临床表现、实验室检查、CT及^(99)Tc^(m)-亚甲基二膦酸盐(MDP)SPECT/CT全身骨显像等方面分析了该病的特点,并通过文献复习总结了EA的影像学特征。^(99)Tc^(m)-MDP SPECT/CT显像能发现转移灶并与其他疾病进行鉴别诊断,具有一定的临床价值。

Bone epithelioid angiosarcoma(EA)is a highly malignant bone tumor of vascular endothelial origin.Bone EA is a rare disease in clinical practice.A case of femoral EA with^(99)Tc^(m)-methylenediphosphonate(MDP)SPECT/CT was reported and reviewed in terms of clinical symptoms,laboratory examination,CT and^(99)Tc^(m-MDP SPECT/CT imaging,the imaging features of EA were summarized by literature review.^(99)Tc^(m)-MDP SPECT/CT imaging is helpful for the detection of metastatic and the differential diagnosis of EA from other diseases,which has certain clinical significance.
