Brain Surgery - Intracerebral Tumor with Blockage of CSF Circulation

This stock medical exhibit shows an intracerebral tumor with blockage of cerebrospinal fluid (CSF) circulation in a series of illustrations. The first illustration shows the normal anatomy of the brain in a coronal section, including the cerebrum, superior sinus, lateral ventricle, third ventricle and optic tract. The second illustration shows normal anatomy of the brain in a mid-sagittal view, including some of the previously mentioned structures and the pineal gland, cerebral aqueduct, fourth ventricle, subarachnoid space of the spinal cord, and the pathway of CSF circulation. The third illustration shows the actual condition in a coronal section of the brain, including the dilation of the ventricles from accumulated CSF, blockage of CSF circulation from the third ventricle by a tumor and a compromised optic tract due to raised intracranial pressure. The fourth illustration shows the actual condition of the brain in a mid-sagittal section, including the blocked CSF circulation from the third ventricle by the tumor. The fifth illustration shows the location of the ventriculoperitoneal shunt in a coronal section of the brain. The sixth illustration is an enlarged view of the fifth, showing the drainage of CSF through a cannula inserted into the lateral ventricle, the location of the intracerebral tumor and the decompression of the optic tract.
