Abstract
The eight-and-a-half syndrome is a rare neuro-ophthalmological condition caused by a structural lesion in the dorsal portion of the pons, involving critical areas of the brainstem, i.e., medial longitudinal fasciculus (MLF), abducens nucleus, facial genu, and colliculus. It is characterized by internuclear ophthalmoplegia with horizontal gaze palsy and peripheral facial palsy. Although the syndrome is most frequently caused by vascular or demyelinating diseases, several different underlying causes might occur. Herein, we describe a case of the eight-and-a-half syndrome caused by a lung adenocarcinoma metastasis localized in the lower pontine tegmentum. Then, we review the current literature on the underlying causes of the eight-and-a-half syndrome.

Abstract
Nine syndrome is a rare clinical entity with core clinical signs of one and a half syndrome, ipsilateral facial palsy, and contralateral hemiparesis/hemianesthesia and localizing to the dorsal paramedian pontine tegmentum. The awareness of this sign helps in precise localization and consideration of relevant aetiologies. Here, we report a case consisting of right horizontal gaze palsy with right internuclear opthalmoplegia and right lower motor neuron type VII nerve palsy constituting eight-and-a-half syndrome. With the additional involvement of left upper and lower limb upper motor neuron weakness, it revealed the lesion responsible for the ‘nine’ syndrome in magnetic resonance imaging of the brain. It is our purpose to highlight the genesis of this combination of clinical signs.

Abstract
RATIONALE "Nine" syndrome, that is "eight-and-a-half" syndrome associated with hemiplegia and hemidysesthesia, is a rare disorder. This study aimed to report a Chinese patient with acute bilateral pontine infarction manifesting as eight-and-a-half syndrome plus hemiplegia (atypical nine syndrome), and also the clinical and neuroimaging findings were explained and discussed with review of the literature. PATIENT CONCERNS A 79-year-old woman experienced sudden vertigo, nausea, vomiting, and weakness at her left arm and leg. The neurological examination disclosed her right horizontal gaze palsy, internuclear ophtalmoplegia (INO), and right-sided peripheral facial paralysis combined with slight left-sided hemiplegia, which were consistent with atypical nine syndrome. DIAGNOSES Cranial magnetic resonance imaging (MRI) displayed acute multiple ischemic infarction, involving bilateral pontine tegmentum, basilar part of right paramedian pontine, and left cerebellar hemisphere. Intracranial MR angiography (MRA) revealed right middle cerebral artery occlusion, no clear visualization of bilateral vertebral arteries, and basilar artery hypoplasia with stenotic segments. INTERVENTIONS Thrombolysis could not be performed due to the time window. The patient was given low molecular weight heparin for anticoagulation because of posterior circulation and progressive stroke. OUTCOMES The vertigo disappeared, and a notable improvement with minimal restriction in the right horizontal gaze and partial relief of her facial paralysis were found at discharge, while her left hemiparesis was fully resolved. No recurrence of cerebral infarction was observed during follow-up as well. LESSONS This case report with atypical nine syndrome is fairly rare. Nine syndrome may refer to the lesion located in unilateral tegmentum of the caudal pontine plus paramedian pontine, with an important localization value.

Abstract
The pathologic involvement of brainstem and midbrain nuclei and white matter tracts in various combinations may result in a spectrum of arithmetically derived syndromes. They include ‘one and a half syndrome’, ‘eight and a half syndrome’ and ‘fifteen and a half syndrome’. We report a case of ‘nine syndrome’, which has been reported more recently, caused by caused by acute pontine infarcts and characterised clinically by a combination of internuclear ophthalmolplegia, ipsilateral horizontal gaze palsy, lower motor neuron type of facial palsy, contralateral hemiparesis and hemianesthesia. We highlight the genesis of this combination of clinical signs, revisit the different variants of INO and review the literature on ‘Nine syndrome’.

Abstract
The one and a half Fisher syndrome is produced by an unilateral lesion in the dorsal and inferior part of the pons located specifically in the pontine tegmentum. This is an area that contains the medial longitudinal fasciculus (LMF), the paramedian pontine reticular formation (PPRF) and the nucleus of the sixth cranial nerve, responsible for the horizontal movements of the gaze. Clinically it manifests with conjugate gaze palsy with internuclear ophthalmoplegia. The case is reported on a 60 year-old patient, who presented with binocular diplopia, ophthalmoplegia and paralysis of the gaze conjugated to the left. Imaging studies were performed that showed a hemi-protuberant haematoma secondary to a cavernoma. As expected, he presented with several episodes of re-bleeding with clinical worsening: headache, diplopia, tetraparesis, and hypoaesthesia in the right side of the face, as such that the microsurgical exeresis of the protuberant cavernoma was considered.

Abstract
Eight-and-a-half syndrome, a combination of one-and-a-half syndrome and ipsilateral facial palsy, was first described by Eggenberger in 1998. Intracranial capillary telangiectasia (ICT) is a rare type of latent cerebral vascular malformation characterized by a number of small, dilated, and thin-walled blood capillaries with normal brain tissues between them. Susceptibility weighted imaging is the recommended diagnostic method to detect ICT. Oommen once reported 1 case about pontine hemorrhage causing Fisher one-and-a-half syndrome with facial paralysis. Here, we report a case with regard to pontine tegmentum ICT and hematencephalon presenting as eight-and-a-half syndrome.

Abstract
This case talks about ‘One-and-a-half plus syndrome’, a clinical syndrome affecting binocular vision and facial nerve. One-and-a-half plus syndrome is a less known clinical syndrome which constitutes of a conjugate horizontal gaze palsy in one direction and an internuclear ophthalmoplegia in the other direction. Despite the known association between ischemia, autoimmune disorders, multiple sclerosis, with mono neuritis multiplex resulting in extra ocular movement disorder, one-and-a-half plus syndrome is rarely considered in the differential diagnosis of eye ball movement disorders, as many clinicians are not able to diagnose such a case as ‘ the eyes don’t see what the mind doesn’t know’. Our report aims to raise awareness about connective tissue disorders presenting as neuro-ophthalmological syndrome, as early recognition can accelerate diagnosis and decrease the morbidity.

Abstract
Eight-and-a-half syndrome is a rare condition that is described as a combination of one-and-a-half syndrome and an ipsilateral facial nucleus lesion. We present a clinical case of occurrence of eight-and-a-half syndrome that was caused by a demyelinating lesion in the dorsal pontine tegmentum. A 44-year-old man presented to the hospital with a subacute onset of horizontal diplopia and left-sided facial weakness. MRI revealed a T2 hyperintense lesion in his dorsal pons, which was consistent with a demyelinating pathology. Treatment with intravenous steroids showed significant improvement in his symptoms. In our case, it occurred due to a suspected demyelinating lesion that was this patient's first and only demyelinating event, leaving him with a diagnosis of clinically isolated syndrome. His responsiveness to steroids represents the first case report of an adult patient presenting with an eight-and-a-half syndrome secondary to a suspected demyelinating pathology.

Abstract
BACKGROUND Eight-and-a-half syndrome is caused by a lesion in the dorsal tegmentum of the caudal pons involving parapontine reticular formation and median longitudinal fasciculus, as well as the nucleus and/or the fasciculus of the facial nerve. It is characterized by one-and-a-half syndrome and an ipsilateral cranial nerve VII palsy. Also, many variants of eight-and-a-half syndrome have been described, including nine syndrome, thirteen-and-a-half syndrome and fifteen-and-a-half syndrome. METHODS We describe a case of a 49-year-old man who presented with eight-and-a-half syndrome combined with contralateral hemiparesis. We reviewed the literature describing the related spectrum of eight-and-a-half syndrome associated with various etiologies. RESULTS Brain computed tomography scan revealed a hyperdensity located in the left paramedian aspect of the dorsal pons. T2-weighted magnetic resonance imaging at the 11-month follow-up showed hyperintensity and enlargement of the inferior olivary nuclei, which were compatible with a diagnosis of hypertrophic olivary degeneration. In light of our observations and cases reported in the literature, we categorize the spectrum of eight-and-a-half syndrome into three types, namely classic eight-and-a-half syndrome, eight-and-a-half syndrome variants and eight-and-a-half plus syndrome. Besides, the clinical feature and outcome of the three types are discussed in this article. CONCLUSIONS Recognition of the spectrum of eight-and-a-half syndrome allows precise anatomic localization of the lesion to pontine tegmentum region.

Abstract
One-and-a-half syndrome is a syndrome characterized by horizontal movement disorders of the eyeballs, which was first reported and named by Fisher in 1967. It presents a combination of ipsilateral conjugate horizontal gaze palsy (one) and ipsilateral internuclear ophthalmoplegia (INO) (a half). On the basis of the one-and-a-half syndrome, there are a series of related rare syndromes called the one-and-a-half syndrome spectrum disorders. This article reviews rare cases of one-and-a-half syndrome spectrum disorder, describes the clinical and pathological features of different syndromes, and summarizes their nomenclature.

Abstract
“Eight-and-a-half” syndrome is a rare condition involving the ipsilateral abducens nucleus or paramedian pontine reticular formation (PPRF), the ipsilateral medial longitudinal fasciculus (MLF), and the adjacent facial colliculus/facial nerve fascicle. The condition is often caused by a lesion (vascular or demyelinating) in the dorsal tegmentum of the caudal pons. There are new variants of this syndrome caused by extension of lesion to involve new adjacent structures in pontine tegmentum.
