Bilateral basal ganglia infarction following resection of a right parietal parasagittal dural tumour requiring sinus repair -- an atypical complication of an atypical venous drainage.

The case of a 68-year old woman who underwent surgery for a right parietal parasagittal dural tumour is reported. In the preoperative angiography the straight sinus failed to show. During tumour resection the lateral wall of the parietal superior sagittal sinus was opened and reconstructed.

Case history: multicentric glioma with involvement of the optic chiasm.

The case is reported of a man, aged 68, with a right-sided temporal glioblastoma multiform and a left sided chiasmal anaplastic glioma, as well as an occipital tumor, presumably of glial nature. The patient had a complete prostatectomy of adenocarcinoma a year before. The coincidence of multicentric gliomas and prostate cancer is briefly discussed.
