Abducens internuclear neurons, which project to the contralateral medial rectus subnucleus of the oculomotor nucleus via the medial longitudinal fasciculus 3. Neurons that project to the cerebellar flocculus The genu of the facial nerve curves over the dorsal and lateral surfaces of the nucleus, while the medial longitudinal fasciculus lies medial to each nucleus. A chronic sixth-nerve paresis, even if isolated, may be neither benign nor idiopathic. We describe five patients with tumors in the basisphenoid region manifested clinically by isolated, unilateral abducens paresis for five to 20 years. There were three meningiomas (one confirmed by biopsy, two presumed), a neurilemmoma, and a chondrosarcoma. Isolated abducens paresis may persist for years in Dear Sir, We report on two patients with the clinical sign of isolated bilateral paresis of the sixth cranial nerve. A 66‐year‐old male patient complaining of double vision showed an almost complete left‐sided and a moderate right‐sided paresis of the abducens nerve.

Abducens nerve palsy, or sixth nerve palsy, results in weakness of the ipsilateral lateral rectus muscle. Clinical presentation Patients present with horizontal diplopia with an inability to abduct the ipsilateral eye, thereby resulting in an e 2001-06-01 · PURPOSE: To describe two cases with bilateral abducens nerve paresis associated with serum anti-GQ1b IgG antibody. METHODS: Case reports.

After an extensive imaging diagnostic procedure, we also documented a peritonsillar abscess and various types of thromboses in intracranial and extracranial veins. Ocular muscle palsies are well known complications of herpes zoster ophthalmicus, especially those involving the third nerve. The prognosis for these palsies is usually good with most cases This is most likely the cause of the left abducens nerve paresis, evidenced by medial gaze deviation and lateral rectus atrophy. Smaller left abducens nerve compared to the right presumably represents atrophy secondary to the involved abducens nucleus. 1 article … However, few cases of only bilateral abducens paresis with this antibody have been described. 1,2 Recently, we evaluated two teenaged patients with bilateral abducens paresis associated with the anti-GQ1b IgG antibody.

The tumor may be located within the … We describe an unusual and clinically confusing case of a young woman with an acute paresis of the abducens nerve and partial paresis of the right oculomotor nerve. After an extensive imaging diagnostic procedure, we also documented a peritonsillar abscess and various types of thromboses in intracranial and extracranial veins.

As in these cases, the experience with our patients suggests that the abducens nerve is more vulnerable to the anti-GQ1b IgG antibody than are other cranial nerves and that bilateral abducens palsy is a characteristic sign of the pathologic state. Causes for abducens nerve paresis are due to many neurosurgical diseases, such as Unruptured Cavernous Carotid Aneurysm, Chronic Intracranial Hypertension and tumors [7,8].

Dumas S, Shults WT. Posterior fossa aneurysms comprise a minority of intracranial aneurysms, but produce a wide array of signs and symptoms. We describe an unusual and clinically confusing case of a young woman with an acute paresis of the abducens nerve and partial paresis of the right oculomotor nerve.
