Summary
The authors report a case of tentorial sinus draining the telencephalic and diencephalic tributaries of the basal vein. Dorsally the sinus joined the straight sinus and later the confluence of the sinuses. Attention should be paid to this normal variation whenever a transtentorial surgical approach is considered.
Résumé
Les auteurs rapportent un cas de sinus de la tente du cervelet drainant les affluents télencéphaliques et diencéphaliques de la veine basale. En arrière, le sinus rejoint le sinus droit puis le torcular. Une attention particulière pré-opératoire devrait être accordée à la mise en évidence de cette variété lorsqu'une approche transtentorielle est discutée.
