fig1
To reveal the internal bony landmarks, horizontal cuts were made through temporal bone, frontal bone, and occipital bone of the skull using a schissel and a hammer (Figure 1).
Frontal/superior view of the occipital bone and the misalignment of internal occipital crest (IOC) and internal occipital protuberance (IOP).

fig2
The internal occipital protuberance and groove for superior sagittal sinus are shifted to the right of the skull, as shown in Figures 2 and 3. As seen in Figures 2 and 4, there is a smaller cavity for right occipital lobe and right cerebellar hemisphere.

The internal occipital protuberance and groove for superior sagittal sinus are shifted to the right of the skull, as shown in Figures 2 and 3.
Superior view showing the reduction of space of the right side due to the shift of internal occipital protuberance to the right compared to the left side of the skull.

fig4
As seen in Figures 2 and 4, there is a smaller cavity for right occipital lobe and right cerebellar hemisphere.
Dura mater with superior sagittal sinus (SSS), two transverse sinuses (TS), and confluence of sinus (CS) joining the three sinuses.

 Figure 5 shows that there were no abnormalities associated with dura mater, superior sagittal sinus, transverse sinus, and confluence of the sinus.
Sagittal dissection of the brain (a) and horizontal dissection of the brain (b). This figure shows absence of inflammation of the brain and the size differences between right and left cerebrum.

fig6
Two different dissections of the brain are shown in Figure 6. As Figure 6 horizontal dissection shows, the posterior regions of left and right occipital lobe do not align with each other.
