✓ 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.

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.

✓ 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.

Object. The purpose of this study was to identify factors predictive of postoperative oculomotor nerve palsy among patients who undergo surgery for distal basilar artery (BA) aneurysms. The data can be used to estimate preoperative risk in this population. The natural history of oculomotor nerve palsy in patients with good outcomes is also defined. Methods. The cases of 163 patients with distal BA aneurysms, who were treated surgically between 1996 and 2002, were retrospectively studied to identify factors contributing to oculomotor nerve palsy. After the data had been collected, stepwise logistic regression procedures were used to determine the predictive effects of each variable on the development of oculomotor nerve palsy and to create a scoring system. Factors that interfered with resolution of oculomotor dysfunction in patients with good outcomes were also studied. Postoperative oculomotor nerve palsy occurred in 86 patients (52.8%) with distal BA aneurysms. The following factors were associated with postoperative oculomotor dysfunction, as determined by a categorical data analysis: 1) younger patient age (p < 0.001); 2) poor admission Hunt and Hess grade (p < 0.001); 3) use of temporary arterial occlusion (p < 0.001); 4) poor Glasgow Outcome Scale score (p < 0.001); and 5) the presence of a BA apex aneurysm that projected posteriorly (p < 0.001). For patients with good outcomes, postoperative oculomotor nerve palsy resolved completely within 3 months in 31 patients (52%) and within 6 months in 47 patients (80%). The projection of the BA aneurysm was associated with incomplete oculomotor recovery at 6 months postoperatively (p = 0.019). Conclusions. The results of this study can help identify patients with a high risk for the development of oculomotor nerve palsy. This may help neurosurgeons in preoperative planning and discussions.

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.

✓ Macroprolactinomas rarely present with apoplexy. The authors describe a patient with a macroprolactinoma who presented with apoplexy and rapid progression of a third nerve palsy. The patient was managed expectantly with bromocriptine, and within 48 hours, the patient's third nerve palsy had completely resolved. The authors suggest that all patients who present with pituitary apoplexy in the presence of a pituitary tumor receive an immediate course of bromocriptine and steroid therapy until the prolactin level can be determined. Emergency surgery is indicated if visual function is abnormal and the tumor is not a prolactinoma.

Object. The goal of this study was to assess the value of computerized tomography (CT) angiography as a diagnostic tool in isolated oculomotor nerve palsies. Methods. One hundred consecutive patients who presented with an isolated third nerve palsy were examined by CT angiography. This procedure was followed by conventional cerebral angiography in most patients in whom a vascular abnormality was noted on the CT angiography. Thus, all patients whose symptoms were caused by a compressive aneurysm were identified. The remaining patients were observed clinically to exclude the possibility that a missed cerebral aneurysm caused the isolated third nerve palsy. Eighteen patients harbored a cerebral aneurysm responsible for causing the isolated third nerve palsy. Most of the remaining patients experienced some degree of spontaneous recovery. There was no clinical evidence to indicate that a case of compressive cerebral aneurysm causing the isolated third nerve palsy had been missed on CT angiography. Conclusions. Computerized tomography angiography is a reliable diagnostic tool for use in the assessment of patients with an isolated third nerve palsy; it can identify the minority of patients in whom conventional cerebral angiography may be required.

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.

✓ Of the cerebral vascular lesions that can be treated with intravascular detachable balloon techniques, carotid-cavernous sinus fistulas and vertebro-vertebral fistulas have the best results. The great advantage of this technique is that the cerebral blood flow can usually be preserved after the occlusion of the fistula. The authors report 17 posttraumatic carotid-cavernous sinus fistulas successfully treated with preservation of the carotid blood flow in 12 cases. None of the patients died, and the morbidity was limited to one case of third nerve palsy. The treatment of aneurysms by this method is, however, much more difficult and dangerous. Of 14 cases treated, seven good results were obtained. Two patients died and two had a poor outcome. The embolization of certain brain angiomas with calibrated-leak balloons using bucrylate promises to be important in the future.
