CONGENITAL MALFORMATIONS OF BRAIN USING A 3 TESLA MRI-AN INSTITUTIONAL EXPERIENCE

Abstract

AIMS AND OBJECTIVES: To identify the different   presentations and frequency of the various congenital malformations presented in our tertiary care institution over a period of four years.

 MATERIAL &METHODS: MRI Brain using head coil was done in patients attending paediatrics outpatient department and those admitted in paediatrics and neonatology ward presenting with developmental delay and neurological problems .

RESULTS: Congenital abnormality was present in 4% of patients of our study .Most frequently was posterior fossa malformation (1.46%) among which chairi 1 malformation was most common. This was followed by malformations of cortical development (1.33%) among which heterotopias was most common. This in turn was followed by corpus callosum defects (0.8%). Other congenital anomalies were less frequent.

CONCLUSION: Congenital brain anomalies are a major cause of mortality and morbidity in paediatric population some of which may be potentially treatable to various extent. Most of the identified malformations followed the usual pattern .An accurate diagnosis is thus needed to help prevent some of the late complications arising thereof.MRI brain by providing a high spatial resolution and grey-white differentiation  helps us provide the finer details helping  in making a definitive  diagnosis and thus guide management -surgically or medically or both.
