    Notes: Summary Four cases of jugular foramen neurinoma, extending from the posterior fossa into the temporal bone through the jugular foramen, are reported. The information provided by magnetic resonance imaging was compared with that by computed tomography. Due to the excellent sensitivity, the absence of bone artifacts, and the ease of imaging in any plane, magnetic resonance imaging gave better information particularly about the location of the tumour than X-CT scan did. It included the dumb-bell-shaped tumour through the jugular foramen, the extra-axial nature of the tumour, and the precise anatomical relationships between the tumour and the facial and acoustic nerves or the internal carotid artery. Sagittal and coronal views clearly demonstrated the superior and inferior margins of the tumour. The information is very useful not only for preoperative diagnosis but also for planning the surgical approaches and postoperative follow-up.

    Notes: Summary Surgical results of paediatric patients with Moyamoya disease who were treated by indirect revascularization procedures are reported. Encephalo-duro-arterio-synangiosis (EDAS), encephalomyo-arterio-synangiosis (EMAS), and/or encephalo-myo-synangiosis (EMS) were performed on 47 sides of 29 children with Moyamoya disease. The results of those non-anastomotic EC-IC bypass procedures were evaluated clinically, angiographically, and by computed tomography (CT). Postoperative external carotid angiograms showed a good collateral formation through EDAS, EMAS, or EMS in about 70–80 percent of all surgically treated sides. The symptoms such as TIA, RIND, and/or involuntary movements disappeared in the cases with a good collateral formation but not in those with insufficient development of the collateral circulation. The indirect EC-IC bypass surgery seems effective for most of the children with Moyamoya disease who present with ischaemic signs.
