Introduction: Cerebral palsy (CP) is a clinical diagnosis, based upon neurological symptoms and a motor disorder causing an activity limitation. Although neuroimaging is not a prerequisite for the diagnosis of CP according to the Surveillance of Cerebral Palsy in Europe (SCPE), abnormalities are found in over 80% of these patients and MRI is recommended as a part of diagnostic work-up. Characterizing these lesions can elucidate the pathogenic patterns responsible for PC and the structure-function relationship, as well as allowing us to establish a prognosis. Thus, SCPE developed a qualitative classification system called MRI Classification System (MRICS) to standardize the different patterns of CP, categorized from A to E.
Objectives: To present the distribution of Portuguese children with CP in the different categories of the MRICS, as well as unveil the process of classification to the Portuguese neuroradiology community so as to improve the process of categorization.
Materials and methods: Data analysis from active surveillance of 5-years-old children with CP born between 2001 and 2012, residing in Portugal (Programa de Vigilância Nacional da Paralisia Cerebral - PVNPC5A). Classification of MRI based on the predominant pattern responsible for CP,according to the MRICS.
Results: From a total of 2216 registered children, MRIwas performed in 1443 and 1253 were classified based on the report. MRI predominant patterns were: A. Malformations 15% (n=190), B. predominant white matter 38 (n=481), C. predominant gray matter 30% (n=378), D. Miscellaneous 11% (n=132) and E. Normal 6% (n=72). Some clinical data correlation with imaging is also presented.
Conclusion: Neuroimaging is of great importance in the diagnosis of CP. Concise MRI reports of CP children may help improve the establishment of prognosis and early intervention.
