CT EVALUATION OF VARIOUS LINEAR INDICES IN CHILDREN WITH CLINICALLY SUSPECTED HYDROCEPHALUS
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2017, Vol 6, Issue 38
Abstract
BACKGROUND Objective- To prospectively measure and evaluate various CT linear indices namely Cella Media index (CMI), Frontal Horn Index (FHI), Evan’s Index (EI) and Ventricular/Biparietal (V/BP) Ratio in children with clinically suspected hydrocephalus caused by various aetiologies. MATERIALS AND METHODS Axial CT scans of 53 symptomatic children were studied prospectively with proper consent. Out of these 53 patients, 31 were males and 22 were females. All patients had 2-phase examination (pre- and post-contrast studies) of the brain using the department’s Siemens 128 slice somatom definition as multi-detector spiral CT. Predicated on the measurements various linear indices, notably Cella Media Index, Frontal Horn Index, Evan’s index and V/BP Ratio were calculated. RESULTS In our study, meningitis was found to be the most common cause of hydrocephalus in children followed by HIE, aqueductal stenosis and intracranial tumours. Of these 53 cases, 32 had communicating and 21 had non-communicating hydrocephalus. We can grade hydrocephalus based on measured linear indices as mild, moderate and severe. CONCLUSION Our study proved that combination of various indices measured together, rather than single index is better in grading hydrocephalus. CT is a valuable tool in differentiating communicating from non-communicating hydrocephalus depending on the level of obstruction. CT is also useful in determining the aetiology of hydrocephalus in children.
