目的探讨血管畸形和血管中间性肿瘤的影像鉴别诊断。方法回顾性分析58例血管畸形和血管中间性肿瘤患者的影像表现。结果血管畸形42例,CT与MRI显示病变边缘均呈不规则形,边界清晰,CT与X线显示5例病变对邻近骨质产生压迫改变。31例MRI中,T2WI3例呈较高信号(接近脂肪信号),28例呈混杂高信号(高于脂肪信号),其中20例在病变区显示圆形血管样高信号。血管中间性肿瘤16例,CT与MRI显示7例肿块呈类圆形,边界规则,8例肿块呈分叶状,1例边缘呈“蟹爪”状,5例瘤周可见水肿和占位效应,CT与X线显示3例周围骨质产生侵蚀改变,2例肿瘤在骨内可形成溶骨性破坏。11例MRI中,T2WI11例呈较高信号。结论血管畸形和血管中间性肿瘤影像表现不同。
Objective To investigate the differential diagnosis of vascular malformations and intermediate vascular tumors. Methods A retrospective analysis of 58 cases of vascular malformations and vascular tumors in patients with imaging performance. Results Vascular malformations were found in 42 cases. The CT and MRI showed that the edge of the lesion was irregular and the border was clear. CT and X-ray showed that 5 cases had oppression changes in the adjacent bone. Among 31 cases of MRI, T2WI showed higher signal (close to fat signal) in 3 cases and mixed high signal (higher than fat signal in 28 cases), of which 20 showed circular blood vessel-like high signal in the lesion area. Among the 16 cases, there were 16 cases of intermediate vessels in blood vessels. CT and MRI showed that the tumors were round in shape. The boundary was regular. There were 8 lobes with lobes. One of them showed “crab claw” margin. Bit effect, CT and X-ray showed three cases of bone erosion around the change, two cases of tumors in the bone can form osteolytic destruction. 11 cases of MRI, T2WI11 cases showed a higher signal. Conclusions Vascular malformations and intermediate vascular images show different images.
