PURPOSE To elucidate the abnormality of interictal regional cerebral blood flow (rCBF) of West syndrome at the onset. METHODS Quantitative measurement of rCBF with an autoradiography method using N-isopropyl-((123)I) p-iodoamphetamine single photon emission computed tomography (SPECT) was performed on 14 infants with cryptogenic West syndrome. Regions of(More)
We reported the clinical and neuroradiological findings of 8 patients (4 males; 4 females; age range; 3 - 14 years) with posterior leukoencephalopathy syndrome (PLES). Previous case reports suggested that one of the major factors leading to PLES was severe hypertension. We divided the patients into two groups with or without severe hypertension, and each(More)
A retrospective analysis of the clinical and MRI features in 20 Japanese children diagnosed with central nervous system inflammatory demyelinating disorders was performed.
