摘　　要：目的分析21例外伤性基底节出血的CT与MRI表现,探讨其诊断价值。方法收集我院21例外伤性基底节出血的临床、CT和MRI资料,所有病例在伤后马上作CT平扫,在1～3d内作MRI平扫,其中12例加做弥散功能成像(DWI)检查。并对所有病例的CT与MRI表现作回顾性总结。结果发现单纯基底节出血8例;复合性基底节出血13例,合并硬膜下血肿6例,硬膜外血肿3例,蛛网膜下腔出血2例,其他部位脑挫裂伤6例,颅骨骨折4例。21例26个基底节出血灶,其中有11例14个出血灶在苍白球部位,首次CT检查与苍白球钙化无法区别,经MRI检查证实为出血。MRI检查多发现脑挫裂伤灶5个,脑白质剪切伤灶4个。结论CT与MRI结合检查,能够全面、及时、准确地诊断外伤性基底节出血及其合并症,对临床治疗和预后评估有重要价值。Objective To analyze CT and MRI features of traumatic basal ganglia hemorrhage and investigate the diagnostic value. Methods 21 cases with traumatic basal ganglia hemorrhage diagnosed by clinic, CT and MRI in our hospital were collected in this study. Plain CT scan were immediately performed in 21 cases after injury, plain MR scan were performed in 1 to 3 days.12 cases of them underwent diffusion weighted imagine（DWI）. The CT and MRI findings were retrospectively summarized. Results 8 cases were found with simple traumatic basal ganglia hemorrhage. Complexity of basal ganglia hemorrhage occurred in 13 cases, 6 cases combined with subdural hemorrhage, 3 cases with epidural hematoma, 2 cases with subarachnoid hemorrhage, 6 cases with brain contusion and laceration in other locations, 4 cases with skull fracture. 26 lesions of basal ganglia hematoma were showed in 21 cases, 14 lesions of pallidum hemorrhage in 11 cases confirmed by MR could not be distinguished from calcification at the first CT scan. 5 more lesions of brain contusion and laceration and 4 more lesions of brain white matter laceration were found by MR. Conclusion CT in combination with MRI can diagnose traumatic basal ganglia hemorrhage and its complications early, comprehensively and accurately, which plays an important role in the clinical therapy selection and prognosis evaluation.
