Neuro-ophthalmology for neuroradiologists. Left lower motor neuron facial palsy was observed [ Figure 1 ]. Informed consent from the patient was obtained prior to inclusion in the study. The incidence in the general population is 0. Due to their slow-growing but dynamic nature, patients with cavernomas may remain asymptomatic or may only have focal neurologic deficits. She had a left horizontal gaze palsy that could not be overcome with vestibulo-ocular reflex.
In the paramedian access, coagulation of the pre-central cerebellar vein was not necessary, and the entry point to the brainstem was through the lateral mesencephalic sulcus. She had a left horizontal gaze palsy that could not be overcome with vestibulo-ocular reflex. Inability to adduct the eye opposite the lesion past midline gaze. Origin and central course. Focal tumors behave differently from diffuse tumors.
We started dexametasone with good response and again she recovered from facial palsy and improve headaches. The third cranial nerve is a key reference point in this approach. Cerebral aneurysm Intracranial berry aneurysm Charcot—Bouchard aneurysm. The section of the dentate ligament next to the entry of the vertebral artery facilitates mobility of the medulla, and so the lateral access becomes easier, as it avoids opening the condyle. Focal Generalised Status epilepticus Myoclonic epilepsy. Detailed knowledge of the brainstem extrinsic and intrinsic anatomy is essential to avoid morbidity during the surgical approaches.
