title: [A case of clinical Reye syndrome with symmetrical abnormal signal areas in the pons and thalami by MRI].
abstract: We report a two-year-old boy with clinical Reye syndrome. Brain CT disclosed symmetrical low-density areas in the pons and thalami, a part of which was recognized as being of high-intensity on both T1 and T2 weighted MRI. These lesions were suspected of being caused by vascular involvement, since the methemoglobin induced by bleeding may have contributed to the high-intensity regions. The lesions gradually disappeared within four months after the onset, and clinical symptoms also improved markedly without serious neurologic impairment. This case was characterized by the marked improvement in neurological and radiological findings in spite of the serious neurological involvement at onset.
