Olanzapine-induced diabetes in a seven-year-old boy.

The atypical antipsychotics have been recognized to induce diabetes mellitus and ketoacidosis in the adult psychiatric population. This report notes the onset of weight gain, diabetes, and apparent ketosis in a prepubertal boy diagnosed with bipolar disorder and treated with olanzapine. The hyperglycemia rapidly normalized after discontinuation of the olanzapine.

We measured temporal lobe volumes in five children with left middle cranial fossa arachnoid cysts using morphometric analysis of magnetic resonance imaging scans.
