    Notes: Summary Encephalo-duro-arterio-synangiosis (EDAS) is a new surgical operation for childhood moyamoya disease, and its effects have been studied by comparing pre-and postoperative angiograms in 27 patients. The development of collaterals from the external carotid arterial system into the territory of the middle cerebral artery was excellent in 16 of 54 cerebral hemispheres after EDAS, good in 25, and poor in 13. The development of collaterals after EDAS increased as the stenotic process in the internal carotid artery on preoperative angiograms increased except in the most advanced cases, where it seemed to decrease in comparison with the group with middle grade stenosis. After EDAS, not only the superficial temporal artery, but also the adjacent middle meningeal artery participated in forming collateral pathways. Furthermore, decrease of abnormal net-like vessels was observed when there was good to excellent development of collateral vessels. Stenotic lesions in the internal carotid and posterior cerebral arteries were often seen to progress, indicative of the rapidly progressive nature of childhood moyamoya disease. These results appear to suggest that EDAS should be performed as early as possible in childhood moyamoya disease before the occurrence of an irreversible ischaemic state and/or permanent neurological defects.

    Notes: Abstract Our purpose was to evaluate the diagnostic accuracy of MRI in moyamoya disease. We studied 30 patients with this disease, comparing MRI and angiographic findings. The diagnostic value of MRI was evaluated for occlusive lesions, collateral vessels, and parenchymal lesions. In all patients bilateral occlusion or stenosis of the supraclinoid internal carotid artery and proximal anterior and middle cerebral arteries was clearly shown by MRI, and staging of the extent of occlusion agreed with angiographic staging in 44 (73%) of 60 arteries. MRI, particularly coronal images, clearly showed basal cerebral moyamoya vessels in 54 hemispheres, and 45 of a total of 71 large leptomeningeal and transdural collateral vessels were identified. MRI also showed parenchymal lesions in 48 (80%) hemispheres, and the extent of occlusion in the anterior and posterior circulations respectively correlated with white matter and cortical and/or subcortical infarcts.

    Notes: Summary Three autopsy cases of pontine and extrapontine myelinolysis are reported; one, a malignant lymphoma in a man of 66 years, the other an alcoholic liver cirrhosis in a man of 54 years, and an esophageal cancer in a woman of 68 years who presented only with extrapontine myelinolysis, but lacked central pontine myelinolysis (CPM). The extrapontine lesions in these three cases revealed a characteristic and common localization; they occurred mostly (1) in the bundles of myelinated fibers in the gray matter, such as in the pons, basal ganglia, and thalamus; and (2) in the white matter surrounded by massive gray matter, such as the deeper layers of the cortex and subjacent white matter of the crowns and sides of the cerebral gyri, the white matter of the cerebellar folia and internal, external, and extreme capsules. Therefore, the third patient was classified as a subtype of pontine and extrapontine myelinolysis, which may be called the “extrapontine form” because of absence of CPM. Moreover, bilateral demyelination of the mamillary body was found in all cases, and laminar cortical astrocytosis and necrosis similar to Morel's cortical laminar sclerosis in two of them. From the clinical and pathologic findings, the significance of the changed osmolarity of the blood as a cause and the importance of some specificity of the tissue architecture in the pathogenesis are discussed.
