目的评价颅脑CT在小儿结节性硬化症诊断中的价值。方法回顾性分析经临床CT共同确诊的39例小儿结节性硬化症的颅脑CT表现。结果39例小儿结节性硬化症CT平扫表现为颅内钙化或/和非钙化结节,发生于室管膜下39例(100%,)皮质或皮质下15例(38.5%,)脑白质12例(30.8%。)脑实质内可见孤立的斑片状钙化11例(28.2%;)双侧脑室轻度增大21例(53.8%)。结论小儿结节性硬化症的颅内结节多发生于双侧脑室外侧壁室管膜下,CT平扫对颅内高密度或钙化结节具有高度的特异性,是诊断小儿结节性硬化的首选方法。
Objective To evaluate the value of brain CT in the diagnosis of pediatric sclerosis. Methods The CT findings of 39 cases of pediatric tuberous sclerosis diagnosed by clinical CT were retrospectively analyzed. Results The CT findings of 39 cases of children with tuberous sclerosis showed intracranial calcification or / and noncalcified nodules, which occurred in 39 cases (100%) of 15 cases (38.5%) of cerebral cortex or subcortex In 12 cases of white matter (30.8%), isolated patchy calcification was found in 11 cases (28.2%) in brain parenchyma. Conclusion The intracranial nodules in children with tuberous sclerosis mostly occur in the lateral ventricle lateral ependymal membrane. CT scan is highly specific to intracranial high-density or calcified nodules and is a useful tool in diagnosis of tuberous sclerosis The preferred method.
