Clinical outcome and magnetic resonance imaging findings in infants with hypoglycemia.

The authors examined clinical outcome and cranial magnetic resonance imaging (MRI) findings in infants with hypoglycemia to determine the effects of hypoglycemia on the developing brain. A total of 110 infants with hypoglycemia were included in the study. Of the patients, 36 were females and 74 were males. The age of the infants was between 1 day and 22 months. Of the 110 infants, 47 were preterm neonates, 40 were term neonates, and 23 were older than 28 days. No difference in serum glucose level was noted between symptomatic and asymptomatic infants. The most common observed abnormal findings were hyperintense lesions, encephalomalacia, and cerebral atrophy. Abnormal MRI findings were found in 4% of preterm infants, in 32.5% of term infants, and in 43.5% of older infants. Abnormal MRI findings were statistically significantly more common in symptomatic infants than in asymptomatic infants. Of the infants, 45.5% of hypoglycemic infants had cerebral palsy and/or cerebral palsy plus epilepsy.
