Clivuskanten Syndrome

When Clivuskanten syndrome is an important early clinical sign with horizontal displacement of the upper brain stem in tentorial notch. Pressure damage to the oculomotor nerve (3rd cranial nerve ) occurs with rapidly increasing intracranial pressure increases, for example with subdural hematomas after head trauma or bleeding from brain tumors and subsequent paralysis of the oculomotor nerve .

Pathology and symptoms

If the brain stem is pressed down against the cranial bone by increased pressure in the cranial cavity (for example in the case of an epidural hematoma or brain tumors ), the oculomotor nerve is also pressed against a bony structure in the area of ​​the brain stem (clivus edge).

First there is an expansion of the ipsilateral pupil due to irritation and stretching of the nerve in the tentorium slit, then to an oculomotor paralysis with a wide, light-rigid pupil. In the further course there is complete oculomotor paralysis as well as an additional dilatation of the contralateral pupil due to the displacement of the brain stem against the clivus edge.
