We aimed to study the neurovascular relationships between the anterior inferior cerebellar artery (AICA) and the abducens nerve to help determine the pathogenesis of abducens nerve palsy which can be caused by arterial compression. Twenty-two cadaveric brains (44 hemispheres) were investigated after injected of coloured latex in to the arterial system. The anterior inferior cerebellar artery or...

BACKGROUND Gradenigo's syndrome includes the triad of suppurative otitis media, ipsilateral sixth (abducens) cranial nerve palsy and facial pain in the distribution of the fifth (trigeminal) cranial nerve. Gradenigo's syndrome is rare, and the diagnosis is easily overlooked. This case is the first to report Gradenigo's syndrome presenting with meningitis on a background of chronic suppurative o...

While brain stem involvement in multiple sclerosis (MS) is relatively common, isolated cranial nerve palsies are rare, especially when they represent the initial presenting sign of a new diagnosis of MS. This report describes a patient with no prior history of MS whose sole presenting sign was an isolated abducens palsy. An enhancing pontine lesion was found on MRI which correlated with his abd...

Bilateral abducens nerve palsy related to ruptured aneurysm of the anterior communicating artery (ACoA) has only been reported in four patients. Three cases were treated by surgical clipping. No report has described the clinical course of the isolated bilateral abducens nerve palsy following ruptured ACoA aneurysm obliterated with coil. A 32-year-old man was transferred to our institution after...

neurobrucellosis is a rare complication of brucellosis. several clinical forms of brucellosis affecting the cns have been reported, including meningitis, meningoencephalitis, myelitis, radiculoneuritis, cranial nerve involvement, and demyelinating or vascular disease. in this case report we introduce a 2.5 years old girl with unilateral abdocens nerve palsy.

neurons in the paramedian pontine reticular formation responsible for ipsilateral horizontal saccade and (2) gaze centers playing a role in ipsilateral horizontal smooth pursuit. Both gaze centers project to the ipsilateral abducens nucleus which controls both abducens motor neurons (responsible for ipsilateral eye abduction) and internuclear neurons projecting via the medial lateral fasciculus...

BACKGROUND Sixth (abducens) nerve palsy (ANP) is far less frequent in children and has not been reported as a sign of acute disseminated encephalomyelitis (ADEM). We present an infant case of ADEM with bilateral abducens nerve palsy (BANP). CASE PRESENTATION We report one case of BANP in a 15-month-old boy of fulminant ADEM. The patient underwent physical examinations and brain MRI scan three...

Sphenoid sinus mucocoeles can stimulate a variety of pathological conditions and patients can present to a range of specialists. Because of the relative rarity of sphenoid sinus mucocoeles, diagnosis is often delayed and these lesions can progressively expand and cause direct mechanical compression on adjacent structures. We present three cases which presented with an abducens nerve palsy. Earl...

A fifty-two year old postmenopausal woman was admitted to the hospital with complaints of diplopia, headache, humming over the head, and pain over the left eye. Neurological examination showed right abducens nerve palsy. In a few days, she also developed left abducens nerve palsy and chemosis, exophthalmos, and proptosis of both eyes. There was pulsation over the left eye. Intraocular pressure ...

Over a period of 12 years, 80 patients underwent ventricular shunting for normal pressure hydrocephalus. Three developed sixth cranial nerve palsy in the first two weeks after surgery. This uncommon complication is usually transitory following the same pattern of abducens palsy after lumbar puncture or spinal anesthesia. Traction on the nerve with local ischemia has been involved as the respons...
