title: MR imaging and 1H-MR spectroscopy in a case of cerebral infarction with transient cerebral arteriopathy.
abstract: A case of cerebral infarction with transient cerebral arteriopathy in a 12-year-old female is described. The child showed with an acute onset of left hemiplegia, central facial palsy and aphasia. She was diagnosed with right internal carotid artery obstruction with no predisposing factors for cerebral infarction. A serial MR image and MR spectroscopy of the brain was performed. MR angiography revealed reversible vascular changes in the right middle cerebral artery after several months. The ratio of choline/creatine was elevated and that of N-acetylaspartate (NAA)/creatine was depressed in the cerebral lesion, however, they were normalized during the remission phase with long echo time-MR spectroscopy. The elevation of the lactate peak was clarified with short echo time-MR spectroscopy. The longitudinal follow up using MR angiography, and MR spectroscopy with long and short echo time was useful for the evaluation of reversible vascular change with cerebral infarction in children.
