They are usually associated and, practically speak-ing, severe cerebral symptoms are alone produced by thrombi. Throm-bosis may occur in the pial vessels of the convexity and extend intothe longitudinal sinus, or, beginning in the sinus, may invade thecortex and give rise to localized softening and focal manifestations.The entire subject may be conveniently described under the head ofSinus Thrombosis.
