63例弥漫性轴索损伤的多层螺旋CT影像分析

Mului-slice spirai CT imaging analysis of the diffuse axonal injury

目的探讨弥漫性轴索损伤的多层螺旋CT(MSCT)影像特征及诊断价值。方法结合病理改变,分析弥漫性轴索损伤的MSCT征象。结果灰白质交界处点状或小片状出血灶52例(82%);胼胝体、脑干、基底节区或三脑室周围灶状出血9例(14%);蛛网膜下腔出血28例(44%)和(或)脑室内出血16例(25%)例;脑肿胀和(或)脑水肿4例(6%);另发现颅骨骨折、颅内积气及鼻窦、乳突积液等。结论MSCT检查准确率较高,是目前急诊检查诊断弥漫性轴索损伤的有效手段。

Objective To explore the Multi-slice spiral CT（MSCT） imaging characteristics and diagnosis value of the diffuse axonal injury. Methods The MSCT signs of the diffuse axonaI injury were analyzed combining with pathology. Results 52cases（82% ）had spotting or small patchy intracerebral hemorrhage at the gray-wite matter interface. 9cases（ 14% ）had mall spot intracerebral hemorrhage at icorpus callosum, the brain stem, the basal nuclei or surrounding the 3th ventricle,44cases（70% ） had subarachnoid hemorrhage and（or） intraventricular hemorrhage ;4cases（6% ）had cerebral swelling and（or） cerebral edema;We aIso can find skull fracture, cerebral pneumatosis,fluid accumulation in sinus or cellulae mastojdeae. Conclusion MSCT accrate rate is higher than the others in diagnosis for the diffuse axonal injury. It is an efficient method of the emergency examination
