Video Transcript

The intended approach to use was a reopening of the previous posterior transcallosal approach. This is the postoperative MRI after the second procedure showing that the surgical cavity is now significant, and the residual parts of the tumor still lying into the upper part of both the lateral ventricle, and the coronal section help to identify the lesion well illuminated on the right, and left upper part of the surgical cavity just below the corpus callosum. And also, the sagittal T2 drive images of the MRI the two remnants on the right and left lateral ventricle just below the remnant of the corpus callosum, very close to the previous approach.

The decision made to use the same approach was also based on the 3D rendering of the tumor residual, showing that the longest axis still remained the cranial-caudal axis that is better exposed in full by a reopening of the previous transcallosal approach. The multiplanar reconstruction of the trajectory shows that the– presents of the largest surgical cavity may help significantly the surgeon in further dissection and in aiming the final target.
