A 64-year-old man with a midbrain cavernoma and prior bleeding presented with a 1-week history of diplopia, partial left oculomotor nerve palsy, and worsening dysmetria and right-sided weakness. MRI revealed a hemorrhagic left tectal plate and midbrain cavernoma. A left suboccipital supracerebellar transtentorial approach in the sitting position was performed for resection of his lesion utilizing the lateral mesencephalic sulcus safe entry zone. Postoperatively, he developed a partial right oculomotor nerve palsy; imaging depicted complete resection of the cavernoma. He recovered from the right third nerve palsy, weakness, and dysmetria, with significant improvement of his partial left third nerve palsy.The video can be found here: https://youtu.be/ofj8zFWNUGU.

A 69-year-old woman presented with an 8-month history of diplopia and examination findings consistent with a right third-nerve palsy. Head MRI identified the presence of a 5.8 mm, nodular, isointense lesion in the suprasellar cistern, which demonstrated enhancement with gadolinium contrast. The lesion did not show any evidence of growth over a 3-month follow-up period. These MRI findings, alongside the clinical features, suggest oculomotor nerve schwannoma. Oculomotor schwannomas are a rare cause of third-nerve palsy. The presenting features and management options for oculomotor schwannomas are discussed to provide a framework for the diagnosis and management of these patients.

Third Nerve

Patients with intracranial aneurysm located at the internal carotid artery-posterior communicating artery (ICA-PComA) often present pain on the orbit or fronto-temporal region ipsilateral to the aneurysm, as a warning sign a few days before rupture. Given the close proximity between ICA-PComA aneurysm and the oculomotor nerve, palsy of this cranial nerve may occurduring aneurysmal expansion (or rupture), resulting in progressive eyelid ptosis, dilatation of the pupil and double vision. In addition, aneurysm expansion may cause compression not only of the oculomotor nerve, but of other skull base pain-sensitive structures (e.g. dura-mater and vessels), and pain ipsilateral to the aneurysm formation is predictable. We reviewed the functional anatomy of circle of Willis, oculomotor nerve and its topographical relationships in order to better understand the pathophysiology linked to pain and third-nerve palsy caused by an expanding ICAPComA aneurysm. Silicone-injected, formalin fixed cadaveric heads were dissected to present the microsurgical anatomy of the oculomotor nerve and its topographical relationships. In addition, the relationship between the right ICA-PComA aneurysm and the right third-nerve is also shown using intraoperative images, obtained during surgical microdissection and clipping of an unruptured aneurysm. We also discuss about when and how to investigate patients with headache associated with an isolated third-nerve palsy.

Palsy of the third cranial nerve (oculomotor nerve, CNIII) is a well-known clinical presentation of posterior communicating artery (P-com) aneurysm. We report a series of 11 patients with partial or complete third nerve palsy secondary to P-com aneurysm. All were treated with endovascular embolization within seven days of symptom onset. Third nerve palsy symptoms resolved in 7/11 (64%), improved in 2/11 (18%) and did not change in 2/11 (18%) patients

Recurrent painful ophthalmoplegic neuropathy (RPON), previously called ophthalmoplegic migraine, is a rare condition characterised by recurrent episodes of headache and ophthalmoplegia. We report a case of 11-year-old girl with recurrent painful ophthalmoplegia due to isolated right oculomotor nerve involvement. MR brain imaging showed enhancing lesion of cisternal segment of right oculomotor nerve. A possibility of Tolosa Hunt syndrome was considered and she was treated with glucocorticoids, followed by azathioprine due to recurrence. In the fourth episode, she developed migraine headache followed by right third nerve palsy, after which the diagnosis was revised to RPON. She was started on flunarizine along with short-term glucocorticoids. At 1-year follow-up, she remained asymptomatic. RPON should be considered in patients with recurrent third nerve palsy to avoid inadvertent long-term exposure to immunosuppressive agents.

✓ Aberrant regeneration of the oculomotor nerve usually follows injury to the nerve by posterior communicating artery aneurysms or trauma. A case of idiopathic third nerve palsy with pupillary involvement occurred in an otherwise healthy 38-year-old man. Follow-up examination 32 months later showed evidence of oculomotor function with aberrant regeneration.

AbstractLesions of the oculomotor nerve as the first sign of pituitary adenoma are rare. The cause of such lesions without other clinical symptoms is discussed in this study. A small cohort of 4 patients (3.1%) with oculomotor nerve palsy (third nerve palsy) as the only neurologic deficit, from 129 patients who got operated upon for pituitary adenomas, is presented. In this group (mean age: 55 years, range: 36–65 years), all patients (two women and two men) underwent surgery. In two cases, there was arrested pneumatization and thickened bone. In the remaining two cases, a macroscopically visible, very solid opaque diaphragm was present, after the removal of the tumor and thickened bone. Complete adjustment was observed in all patients within 1 week after the surgery. Two factors that seem to increase the high risk for the development of oculomotor nerve palsy are that the cavernous sinus may be the only weak structure surrounding the sella turcica when the diaphragm and bone are thickened; and the rapid development of increased pressure in this region. The increased pressure on the cavernous sinus during the anatomical variations is the primary cause for lesions on the oculomotor nerve. However, this conjecture cannot be statistically demonstrated because of the small number of cases. Future research should be conducted on larger samples to increase statistical inference and generalizability.

✓ Forty-two patients with aneurysm-induced third nerve palsy are described. After carotid ligation, 58% showed satisfactory and 42% unsatisfactory functional recovery. In some patients the deficit continued to increase even after carotid ligation. Early ligation provided a better chance of recovery of third nerve function. Patients in whom third nerve palsy began after subarachnoid hemorrhage had a poor prognosis. No relationship was noted between the size of the aneurysm and the recovery of third nerve function.
