15例小儿肌肉内海绵状血管瘤的MRI诊断

MRI Diagnosis of Cavernous in Extremity Muscle of Children

目的 :探讨磁共振成像 (MRI)对肢体深部海绵状血管瘤的诊断价值。方法 :回顾分析 15例下肢肌肉内海绵状血管瘤 ,病例均经手术及病理证实。结果 :12例在T1WI上为稍高信号 ,T2WI上均为高信号 ,信号不均匀 ,边缘不光整 ,肌肉受侵蚀 ,骨骼少受侵蚀。结论

Objective: To evaluate the diagnostic value of cavernous MRI findings in extremity muscle of children. Methods:MRI findings of pathologically proved cavernous were analyzed retrospectively in 15 cases.Results: 12 of the 15 cases were slightly high signal intensity on T1 weighted image(T1WI). 15 cases were all high signal intensity on T2 weighted image(T2WI). All of the cases showed non homogeneous signal intensity with unclear margin. Muscle was invaded by cavernous in all of the cases,but bone was not.Conclusion: MRI may be taken as a good method in diagnosis of cavernous in extremity musclue.
