Introduction: Introduction: Global developmental delay is diagnosed when there is a significant delay in two or more of the following domains of development: gross motor, fine motor, speech and language, cognition, and social/personal development. The etiology of global developmental delay varies from specific diseases to sequelae of perinatal ischemic insult. Determination of causality may or may not lead to treatment modification but has specific implications with regard to prognosis and counseling of the family. Magnetic resonance imaging is the modality of choice in investigating infants and children with developmental delay.
Aim: To study and classify brain magnetic resonance imaging findings in children aged 3 months-18 years who presented with global development delay.
Materials and Methods: Clinical records and imaging studies of 90 developmentally delayed children between the ages of 3 months to 18 years who presented to the Dept of Radio-diagnosis, BMCRI for brain magnetic resonance imaging during September 2013 to August 2014 were analyzed retrospectively.
Results: Out of 90 children (male-44, female-46) who presented to us, abnormal findings were present in 65 (male-32, female-33) (72%), of which most (53) of them had features sequelae to ischemic insult such as periventricular leukomalacia, encephalomalacia and thinning of corpus callosum. 10 of the children (male-3, female-7) had structural malformations including corpus callosum agenesis (4), subcortical nodular heterotopia, etc.
Conclusion: Out of all 72% children with global developmental delay who underwent Magnetic resonance imaging showed positive findings, showing that MRI can contribute significantly to the determination of causality.
