The cortex that surrounds the anterior Sylvian fissure controls important clinical functions. Understanding the variations in its venous drainage is critical to interventional radiologists and surgeons who attempt to treat vascular malformation and/or tumors of this region. In addition, these veins are surgical landmarks in surgery for suprasellar, temporal, and deep frontoparietal lobe lesions, and aneurysms of the middle cerebral artery bifurcation. In this article, the angiographic appearance and cortical territories of the six major variations in the venous drainage of the anterior Sylvian fissure are simplified and presented graphically.
