OBJECTIVE: Hemifacial spasm occurs when a blood vessel compresses against an area near the root exit zone of the facial nerve. Developments in diagnostic neuroimaging have allowed three-dimensional (3D) observation of artery and nerve locations, an effective aid for treatment selection. However, an accurate interpretation of the 3D data remains challenging because imaging representations of complex small vessels are drowned out by noise. We used a noise elimination method to analyze artery and nerve locations and to determine their 3D relationship...

BACKGROUND AND PURPOSE: High-resolution 3D MR cisternography techniques such as 3D T2WI-driven equilibrium radiofrequency reset pulse (DRIVE) are used preoperatively to assess neurovascular anatomy in patients with neurovascular compression syndrome, but contrast between vessels and cranial nerves at the point of neurovascular contact is limited. The postprocessing technique subtraction of 3D T2WI-driven equilibrium radiofrequency reset pulse from contrast-enhanced 3D T1WI (sDRICE) provides both high spatial resolution and excellent contrast in depicting the neurovascular contact...

Here, we present a case of a 55-year-old woman with a 10-year history of hemifacial spasm accompanied by 1-month ipsilateral paroxysmal otalgia. Magnetic resonance imaging revealed the presence of vessels around the facial nerve root. Surgical exploration via suboccipital retromastoid craniotomy showed converging compression of the facial nerve root and intermediate nerve from both sides by an anterior inferior cerebellar artery loop. The patient's hemifacial spasm and ipsilateral otalgia were completely relieved after microvascular decompression of the facial nerve root and intermediate nerve...

Parry-Romberg syndrome (PRS) with hemimasticatory spasm (HMS) is quite an uncommon overlapping phenomenon which very often mimics jaw closing dystonia. A previously healthy 35-year-old female, during her 5(th) month of pregnancy started developing intermittent unilateral painful spasms of jaw while conversation, clinching of teeth, or eating, which led to frequent tongue bites. The spasms were worsened during pregnancy. She used to do certain manoeuvre like sensory tricks in form of touching involved side of the face to relieve the symptoms...

Congential hemifacial spasm is a rare condition that is characterized by the occurrence of paroxysmal hemifacial contractions in neonates. We review the clinical, neurophysiological, neuroimaging, and histopathological findings, as well as the differential diagnosis, therapeutic approach, and outcome of all the described cases. Moreover, we report two new cases including the ictal video-electroencephalography recordings. Hemifacial spasm starts early in life, and is characterized by unilateral, involuntary, irregular tonic or clonic contractions of muscles innervated by the seventh cranial nerve...

Although the mechanism of hemifacial spasm (HFS) is not yet well established, vascular compression of the facial nerve root exit zone and hyperexcitability of the facial nucleus have been suggested. We report a case of HFS in the setting of coinciding intracranial hemorrhage (ICH) of the pons and proximal ligation of the contralateral vertebral artery (VA) for the treatment of a fusiform aneurysm of the distal VA and discuss the possible etiologies of HFS in this patient. A 51-year-old male with an ICH of the pons was admitted to our hospital...

Dolichoectasia is a dilatation and elongation of the arteries, usually affecting intracranial basilar and vertebral arteries. It may cause posterior circulation stroke or transient ischemic attacks independent of atherosclerotic disease. Compression of cranial nerves or brainstem leads to hemifacial spasm, trigeminal neuralgia, or brainstem dysfunction (temporary or permanent). Intracranial bleeding is another possible manifestation. In general, the mortality and morbidity is higher in patients with dolichoectasia...

The role of hypertension in the late onset of hemifacial spasm (HFS) is evaluated in a family, spanning four generations. Magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) revealed a variable anatomical relationship between nervous and vascular structures in the symptomatic cerebello-pontine angle. In one case, showing neurovascular conflict (NVC), microvascular surgical decompression was followed by clinical resolution of HFS. Neuroimaging suggesting NVC was found in all symptomatic patients of the last two generations and in three younger subjects not affected by HFS...

A young female patient, who presented acutely with an unusual movement disorder characterized by hyperkinetic facial movements, was referred to us for hemifacial spasm. The only abnormality on neurological examination was myoclonus of the left perioral and bilateral periorbital muscles, exacerbated by mental tasks. A week later, the patient also presented two generalized tonic-clonic seizures on awakening and was successfully treated with antiepileptic drugs. Laboratory and neuroimaging investigations yielded normal findings...

OBJECT: Neuroimages often reveal that the trigeminal or facial nerve comes in contact with vessels but does not produce symptoms of trigeminal neuralgia (TN) or hemifacial spasm (HFS). The authors conducted this study to determine how often the trigeminal and facial nerves came in contact with vessels in individuals not suffering from TN or HFS. They also investigated the correlation between aging and the anatomical measurements of the trigeminal and facial nerves. METHODS: Between November 2005 and August 2006, 220 nerves in 110 individuals (60 women and 50 men; mean age 55...

BACKGROUND: Eyelid myokymia, unlike myokymia of the other facial muscles, is assumed to be a benign, self-limited disorder. However, no systematic follow-up study has been performed on patients with chronic, isolated eyelid myokymia to verify its benign nature. METHODS: Retrospective single-institution chart review of 15 patients examined between 1983 and 2002 with a diagnosis of isolated eyelid myokymia who have had at least 12 months of follow-up. RESULTS: In all patients, symptoms began as unilateral, weekly or biweekly, intermittent eyelid spasms, and progressed to daily spasms over several months...

We present the case of a 42-year-old woman with a 4-year history of definite multiple sclerosis (MS) and sustained contracture of the left hemiface with marked left deviation of the nose, deepened left nasolabial groove, narrowed palpebral fissure and weakness of the contracting muscles. Needle electromyography showed continuous resting activity of irregularly firing motor unit potentials (MUP) in the left orbicularis oculi (OO) and orbicularis oris, but not in the left frontalis. Simultaneous recording of maximal voluntary contraction of the OO on both sides showed marked preponderance on the right...

Three-dimensional (3D) neuroimages are generally considered useful for neurosurgical practice. Nevertheless, neuroimaging modalities such as 3D digital subtraction angiography and 3D computerized tomography angiography are still insufficient because the resulting images fail to delineate neural structures. Complex neurosurgical procedures are mostly performed in the cerebrospinal fluid (CSF) space of the basal cistern, where vessels and neural structures are present along with the lesion. The magnetic resonance (MR) imaging-derived 3D constructive interference in steady-state (CISS) imaging displays the margin between the CSF and neural structures, vessels, and dura mater in detail, in a two-dimensional fashion...

BACKGROUND: Hemifacial spasm (HFS) is a form of segmental myoclonus often associated with vascular compression of the seventh nerve at its exit in the brain stem. Although a few uncontrolled studies describe the association of arterial hypertension (AH) with HFS, their relationship remains to be elucidated. OBJECTIVES: To compare the clinical and radiologic features of patients with HFS and subjects with blepharospasm (BLS) with special emphasis on the presence of AH...

Seventeen patients with subarachnoid cysticerci received albendazole at doses of 15 mg/kg/day for eight days. All patients also received corticosteroids during the trial. Evaluation of the therapeutic response consisted of the comparison of the number of cysts shown by CT before and three months after treatment, and the evaluation of the clinical status of the patients before and after the trial. Before treatment, the 17 patients had 30 subarachnoid cysticerci, 11 of which were > 50 mm in diameter. Seventeen cysts were located at the convexity of cerebral hemispheres, seven at the sylvian fissure, five at the ambiens cisterns, and one at the cerebellopontine angle cistern...

A 62-year-old female presented with rapid aggravation of long-standing facial spasm occurring within a few months. Neuroimaging and angiography demonstrated compression of the root exit zone (REZ) of the facial nerve by an ipsilateral saccular aneurysm at the left vertebral artery (VA)-posterior inferior cerebellar artery bifurcation, in addition to the elongated VA. Neck clipping of the aneurysm and decompression of the REZ from the elongated VA and clipped aneurysm resulted in complete disappearance of the facial spasm...

Dolichoectasia of intracranial arteries is an infrequent disease with an incidence less than 0.05% in general population. It represents 7% of all intracranial aneurysms. Commonly seen in middle age patients with severe atherosclerosis and hypertension, the affected arteries include the basilar artery, supraclinoid segment of the internal carotid artery, middle, anterior and posterior cerebral arteries; males are more frequently affected. The clinical features of these fusiform aneurysms are divided in three categories: ische-mic, cranial nerve compression and signs from mass effect...
