Right transverse and sigmoid sinus spared.

Case Discussion
This lady was admitted to neurology with headaches and visual changes.
She was six weeks post-partum when these developed.
The investigations showed extensive thombosis through the cerebral venous system and she was managed with warfarin (after discussion about risks during breastfeeding).
