The lateral part of the parietooccipital fissure (Fig. 726) is situated about 5 cm. in front of the occipital pole of the hemisphere, and measures about 1.25 cm. in length. The medial part of the parietooccipital fissure (Fig. 727) runs downward and forward as a deep cleft on the medial surface of the hemisphere, and joins the calcarine fissure below and behind the posterior end of the corpus callosum. In most cases it contains a submerged gyrus. [WP,unvetted]. UMLS:C1744592 sulcus parieto-occipitalis subarachnoid sulcus
