Early prenatal magnetic resonance imaging of glutaric aciduria type 1: case report.

We report on a 22-week-gestation fetus, in which prenatal magnetic resonance (MR) imaging revealed findings suggestive of glutaric aciduria type 1, which was confirmed by postnatal biochemical and imaging data. Well-known postnatal MR imaging characteristics of glutaric aciduria type 1 (eg, reduction of the anterior pole of temporal lobes) could be already present at early stage of fetal brain development. Early prenatal MR imaging may play a pivotal role in the diagnostic workout of this condition.
