Cranial CT in children and adolescents with diabetic ketoacidosis.

Abstract

To determine the effects of diabetic ketoacidosis on the brain, we studied nine consecutive patients between the ages of 6 and 17 years by performing cranial CT on three occasions: on admission, before treatment; 6-8 hr after beginning treatment; and 7 days after admission. Both the pretreatment scans and those at 6-8 hr showed significantly reduced size of the lateral and third ventricles in comparison with the 7-day scans. A comparison of the pretreatment scans with those done at 6-8 hr showed no statistically significant differences. We conclude that the cerebral swelling of diabetic ketoacidosis is usually present before treatment.
