Correlative study of CT and clinical signs on brain atrophic diseases of children.

【Objectives】 To explore the relationship between CT scans of brain atrophy and their clinical characteristics. 【Methods】 187 cases of brain atrophy were analyzed. 【Results】 The major etiologies of brain atrophy in children were perinatal abnormality,infection of central nervous system and brain trauma.They accounted for 41.7、24.1、12.3 percent of all the 187 cases separately.Types of paralysis were related to the range and degree of brain atrophy,it was different between the diffuse atrophic and local group.The incidence of epilepsy was 70.6 percent.It related to the range of brain atrophy.The larger range of brain atrophy,the higher incidence of epilepsy.The epileptic incidence of diffuse atrophy was higher than that of local and central atrophy dramatically. 【Conclusion】 In the diagnosis of intracranial diseases,CT can show the intracranial structure exactly,and its manipulation is rapid and safe.Being a useful tool for clinical diagnosis and prognostic judgment,CT is one of the most reliable technique in the diagnosis of brain atrophy at present.
