Interhemispheric View of the Quadrigeminal Cistern and Quadrigeminal Plate

Surgical Correlation


Interhemispheric view of the quadrigeminal cistern and quadrigeminal plate. The straight sinus within the falx cerebri is retracted medially to reveal the superior and inferior colliculi of the quadrigeminal plate, looking rostrally toward the midline pineal gland. Within the quadrigeminal cistern are the superior cerebellar arteries and the precentral cerebellar vein. Just dorsal to the pineal gland is the splenium of the corpus callosum, with its associated splenial arteries (branches of the parieto-occipital branch of the posterior cerebral artery) and posterior pericallosal vein. The basal vein of Rosenthal joins the internal cerebral vein and the precentral cerebellar vein to drain into the midline great cerebral vein of Galen and ultimately to the straight sinus. Laterally, calcarine branches of the posterior cerebral artery course along the medial occipital lobe. (Image courtesy of AL Rhoton, Jr.)
