title: Cerebral 1H MR spectroscopy showing elevation of brain guanidinoacetate in argininosuccinate lyase deficiency.
abstract: MR spectroscopy in a patient with argininosuccinate lyase deficiency revealed elevated cerebral guanidinoacetate signals, indicating that the phenomenon of increased levels of this compound in brain tissue is not limited to creatine deficiencies.
