肌肉内血管瘤的MRI诊断

MRI diagnosis of the intramuscular hemangioma

探讨肌肉内血管瘤的MRI诊断价值。方法:回顾性总结15例经手术和病理证实的肌肉内血管瘤的MRI表现 结果:15例MRI检查见软组织肿块,T_1WI呈等信或稍高信号T_2WI旱高信号,其中10例信号不均匀,5例可见肿瘤内流空血管影;13例注射Gd-DTPA后扫描肿瘤呈明显强化 结论:MRI可以帮助确诊肌肉内血管瘤,对确定手术范围有重要的价值。

Qingyuan People's Hospital of Guangdong Province,Qingyuan 511500,China This is an evaluation of MRI in the diagnosis of the intramuseularbemangioma. Materials and Methods: The MRI findings in 15 cases of intramuscular bemangioma were retrospectively analyzed. All the cases were proved by surgery and pathology- Results: In MRI, the intramuscular hemangioma represented an intramuscular mass with homogeneous or slightly high intense signal on T1WI and extremly hyper intense signal on T2WI. There were mhonloge-neous intense ignal in 10 cases. In 5 cases the blood vessels of the tumor were revealed by flowing voideffecl. After the administration of Gd - DTDA, the lesions were significantly enhanced in 13 cases. Conclusion: MRI is a valuable examination in diagnosis of the intramuscular hemangioma and helpful in confirming the extent of lesion to be removed in surgery.
