Middle cerebral veins

The middle cerebral veins - are the superficial and deep veins - that run along the lateral sulcus. The superficial middle cerebral vein is also known as the superficial Sylvian vein, and the deep middle cerebral vein is also known as the deep Sylvian vein. The lateral sulcus or lateral fissure, is also known as the Sylvian fissure.

Superficial middle cerebral vein

The superficial middle cerebral vein begins on the lateral surface of the hemisphere. It runs along the lateral sulcus to empty into either the cavernous sinus, or the sphenoparietal sinus. It is adherent to the deep surface of the arachnoid mater bridging the lateral sulcus. It drains the adjacent cortex.

Anastomoses

At its posterior extremity, the superficial middle cerebral vein is connected with the superior sagittal sinus via the superior anastomotic vein, and with the transverse sinus via the inferior anastomotic vein.

Deep middle cerebral vein

The deep middle cerebral vein receives tributaries from the insula and neighboring gyri, and runs in the lower part of the lateral sulcus.
