Microencephaly in macrocephaly: Rare report of two siblings with glutaric aciduria type 1

Glutaric aciduria type 1: MR findings in two cases.

Glutaric aciduria type 1 is an autosomal recessive metabolic disorder caused by a deficiency of glutaryi-CoA dehydrogenase. This disorder is characterized by progressive dystonia and dyskinesia. Laboratory evaluation demonstrates excessive levels of glutaric acid urinary excretion as well as absence of demonstrable functional levels of glutaryi-CoA in fibroblast cultures. We present the CT and ...

Bilateral arachnoid cysts of the sylvian region in female siblings with glutaric aciduria type I. Report of two cases.

Two sisters, aged 6 and 2 1/2 years, presented with macrocephaly and delayed motor development and were found on computerized tomography to have bilateral arachnoid cysts of the sylvian region. Cystoperitoneal shunting of the larger cysts resulted in considerable neurological improvement in both children. Subsequent screening of the patients' urine for organic acids showed that the two sisters ...

Glutaric aciduria type 1 in adulthood.

Macrocephaly and bitemporal arachnoid cysts not associated with glutaric aciduria type I in a child.

A 45-month-old child who had bitemporal arachnoid cysts and macrocephaly unrelated to glutaric aciduria type 1 (GA 1) was reported. The patient was admitted to the emergency unit after head trauma at 11 months of age. CT and MRI showed bitemporal arachnoid cysts (BACs). Acylcarnitine profile was normal in serum using tandem mass spectrometry. Urine and blood screening tests were within normal r...

Glutaric Aciduria Type 1 in Korea: Report of Two Novel Mutations

Glutaric aciduria type I (GA I) is an autosomal recessive disorder caused by a deficiency of glutaryl-CoA dehydrogenase. Although over 400 patients confirmed as GA I have been reported, reports from the Asian population had contributed to the minor proportion. We recently diagnosed two cases of GA I confirmed with mutational analysis. Here, we present their rather atypical clinical presentation...
