Lateral View of the Lateral Ventricles and Surrounding Structures

Surgical Correlation


Lateral view of the lateral ventricles and surrounding structures. The middle temporal gyrus has been resected to reveal the temporal horn of the lateral ventricle and hippocampus. The body of the lateral ventricle is bordered superiorly by the corpus callosum. Pericallosal arteries (of the anterior cerebral arteries) curve along the corpus callosum to supply the cingulate gyrus and medial frontal and parietal lobes. Within the inner curve of the lateral ventricle is the fornix, which is continuous caudally with the fimbriae of the hippocampus. Within this curve is the cleft called the choroidal fissure, through which the choroid plexus and its associated choroidal arteries and veins lie. (Image courtesy of AL Rhoton, Jr.)
