ETIOLOGICAL REVIEW OF BRAIN INJURIES ON CT SCANNING IN THE ASSESSMENT OF PSYCHOMOTOR DEVELOPMENT DELAY IN CHILDREN UNDER FIVE (5) YEARS OF AGE AT THE LUXEMBOURG MOTHER-CHILD CHU

Objective: Our workaimed to describe the scan semiology of lesionsencountered in delayedpsychomotordevelopment (DPMD) in childrenunder 5 yearsold at the Mother-Child University Hospital Center Le Luxembourg

Methodology:This is a prospective analytical and descriptive studycarried out over a period of 18 months (from April 15, 2021 to September 15, 2022) in the radiologydepartment of the CHU-ME Mère et Enfant Le Luxembourg. It concerned all patients aged 0 to 5 yearsadmitted to the medicalimagingdepartment of the Luxembourg Mother and Child University Hospital for psychomotordelaywhohadundergone a brain scan. Childrenwithoutpsychomotordelaywereexcludedfromourstudy.

Results:Weretained 150 cases of psychomotordelayduringourstudyperiod. The age group of 0 to 02 yearswas the majority (67%) with an average of 1.33 years, an extreme of 1 month to 5 years and standard deviation of 5.807. The male genderwas in the majoritywith (55%) with a sex ratio of 1.22.The mostcommon type of deliverywas normal deliverywith a frequency of 62.0%. Prematuritywas the mostrepresentedobstetricrisk factor (18.0%).Convulsion was the mostrepresentedneonatalrisk factor (16.7%).Epilepsywas the mostcommon postnatal neurologicalantecedent (6.7%). The scan resultwasabnormalin 75% of our patients. The lesionsfoundwere:anoxo-ischemicleukoencephalopathy (47%), hydrocephalus (17%), malformative lesions (7%), sequelae of brain infections(3%) and tuberoussclerosis of Bourneville (1%)

Conclusion: ChildhoodDPMDrepresents a major healthproblemwith a relatively high prevalence. This studydemonstrates the diagnostic value of CT in the exploration of RPM in children. Of the 150 patients explored, brain CT revealed a lesionin 75.0% of cases.
