Parietal and Occipital Tumors

Figs. 140 to 218
  • Wolfgang Seeger


Anterior margin of the parietal lobe is formed by Sulcus centralis. This is even more recognizable on the lateral surface using axial slices of MRI, similar to anatomical drawing of Fig. 142 than in sagittal slices, which will be compared with median sagittal slices. Here the dorsal end of the sulcus may be seen, as well as Lobulus paracentralis, which is an irregular cortical complex interposed between the regular shaped Gyrus front. I and the Praecuneus. Praecuneus begins posteriorly, at the typical configurated Fissura parieto-occipitalis and ends with its anterior limit at Lobulus parietalis. These structures may not always be defined. But Sulcus parieto-occipitalis presents a typical configuration immediately anteriorly to Lambda and will be easily identified. Bregma, 4 cm anteriorly to Sulcus centralis, will be easily identified, too. Now considerable errors for location of the Sulcus centralis will be excluded.
