RESUMEN
OBJECTIVE: The thromboinflammatory process is considered to play a role in the pathogenesis and prognosis of cerebral sinus vein thrombosis (CSVT). The purpose of the study was to compare the thromboinflammatory parameters between individuals with CSVT and healty controls. Additionally, the study sought to compare these parameters among CSVT subgroups with and without haemorrhage, as well as with and without papilledema. Furthermore, the investigation also aimed to identify which parameters had a more significant impact on the risk of hemorrhage and the development of papilledema in CSVT. METHODS: Thromboinflammatory parameters were compared retrospectively between the CSVT group of 88 patients and 80 age- and sex-matched healthy controls, and in the CSVT subgroups with (n = 35) /without hemorrhage (n = 53) and with (n = 52) /without papilledema (n = 36) after ethics committee approval. In both groups, parameters contributing to the risk of hemorrhage and papilledema development were determined by univariate and multivariate analyses. RESULTS: Regarding the risk of hemorrhage in CSVT patients, the most significant factors included hematocrit of <30.2 (%), mean platelet volume of ≤8.9 fL, neutrophil count of >5600, and hsCRP of >9 mg/L. Regarding the risk of papilledema development, the most important risk factors were age of ≤49, presence of vomiting, presence of blurred vision, HDL of >47 mg/dL, and D-dimer of >178 ng/mL. CONCLUSION: It was suggested that evaluating serum thromboinflammatory parameters, as well as demographic characteristics and neurological examination findings, had a critical role regarding prognosis and predictive factors in CSVT.

Vestibular migraine (VM) is accepted as the most common cause of spontaneous episodic vertigo. In most patients, vestibular symptoms follow migraine headaches that begin earlier in life. The aim of this multicenter retrospective study was to find out the differences between migraine patients without any vestibular symptoms (MwoV) and VM patients and to delineate the specific clinical features associated with VM. MwoV and VM patients were compared regarding demographic features, migraine headache years, headache attack frequency, intensity, symptoms associated with headache and vertigo attacks, presence of menopause, history of motion sickness and family history of migraine. Four-hundred and forty patients with MwoV and 408 patients with VM were included in the study. Migraine with aura was more frequent in patients with MwoV (p = 0.035). Migraine headache years was longer (p < 0.001) and headache intensity was higher in patients with VM (p = 0.020). Aural fullness/tinnitus was more common in patients with VM (p < 0.001) when all other associated symptoms were more frequent in patients with MwoV (p < 0.001) as well as attack triggers (p < 0.05). Presence of menopause and motion sickness history was reported more frequently by VM patients (p < 0.001). Logistic regression analysis indicated that longstanding history of migraine with severe headache attacks, aural fullness/tinnitus accompanying attacks, presence of menopause, previous motion sickness history were the differentiating clinical features of patients with VM.

PURPOSE: To find out clinical features associated with poor response to treatment in vestibular migraine (VM). METHODS: VM patients treated with drugs recommended in migraine prophylaxis were included in this multicenter study. Migraine features including type, age of onset of headache and vertigo attacks, attack frequency, intensity, associated symptoms, triggering factors, presence of interictal dizziness/imbalance, anxiety, depression, history of motion sickness, and family history of migraine were noted. Amitriptyline, flunarizine, propranolol, topiramate and venlafaxine were chosen depending on patients' individual requirements. Maximum dose of each drug was tried for 2 months to decide its efficacy. In the case of inefficacy, it was changed with another preventive drug of different class. If there was still no improvement, two drugs of different classes were combined. ≥ 50% reduction in attack frequency and severity in patients using one drug and a combination of two drugs was compared, with patients showing <50% reduction despite combination therapy, regarding their clinical features. RESULTS: The results of 430 VM patients, 65 men and 365 women with a mean age of 42.2 ± 12.2 years (range: 17-74 years), were analyzed. CONCLUSION: Cutaneous allodynia frequently associated with female sex, comorbid anxiety and depression and interictal dizziness/imbalance enhanced with comorbid anxiety were risk factors for reduced treatment response. Aural fullness might be the clue of impending concomitant Meniere's disease not responding to migraine preventives.

OBJECTIVE: To evaluate demographic and clinical features of vestibular migraine (VM) patients METHODS: Four hundred fifteen patients with VM were evaluated by using a structured questionnaire in addition to clinical examination. RESULTS: The mean age of headache and vertigo onset was 25 years and 39 years, respectively. In 12.3%, benign paroxysmal positional vertigo (BPPV) was detected during the interictal period. Ten percent had hearing loss on audiometry, in 8.7% it was one-sided low-frequency sensory-neural hearing loss below 2000 Hz and the history was typical for Meniere's disease (MD) in addition to VM. Tinnitus was present in 94.4%, aural fullness in 83.4%, nausea in 72.2% and vomiting in 30.5% of patients with VM/MD. The prevalence of these symptoms was higher in patients with VM/MD than in pure VM. Median attack severity determined by visual analog scale measured in centimeters from 0 to 10 was 8 for headache and 7 for vertigo for the whole group. Severe headache was significantly correlated with age of ≤ 43 years (OR: 6.831, 95% CI: [4.10-11.63]; p < 0.001) and severe vertigo was significantly correlated with age ≥ 41 years (OR: 7.073, 95% CI: [4.55-10.98]; p < 0.001). Motion sickness was revealed from past medical history in 51.8%. Family history of migraine was present in 72.5% and the age of onset of both migraine headaches (p = 0.008) and vertigo attacks (p = 0.004) was lower in these patients. CONCLUSION: Younger patients suffered more severe headache attacks whereas vertigo attack severity was higher in the elderly. BPPV and MD were commonly associated with VM and VM/MD was accompanied by aural and autonomic features more frequently than pure VM. Previous history of motion sickness was detected in more than half of the whole group. Family history of migraine was associated with younger onset of migraine headaches and vertigo attacks.

Patients with indirect carotid cavernous fistulas (CCF) were reviewed to emphasize the importance of diagnosing patients even with trivial findings and to raise awareness. Eighteen patients diagnosed as CCF were included. Neuro-ophthalmological findings before and after treatment, diagnostic investigations, treatment, clinical course was noted. Twelve patients were female (67%), 6 were males (33%) and the mean age at presentation was 54 years (range: 29-70 years). Conjunctival hyperemia was present in all patients. Seventeen (94%) patients had proptosis and diplopia, nine (50%) had orbital pain and/or headache, four (22%) had blurred vision, one (5.5%) had ptosis. On examination, 17 patients (94%) had restricted eye movements, four (22%) had low visual acuity and five patients had (28%) increased intraocular pressure (IOP). One patient had been diagnosed as myasthenia gravis and two as thyroid orbitopathy and had been on treatment accordingly before CCF was diagnosed. In two patients, bilateral findings were present despite unilateral CCF on angiography. Barrow Type B fistula was found in 7 (38%), Barrow Type D in 11 (62%) patients. In three bilateral CCF was detected. All were treated by endovascular intervention. Residual deficits at the sixth month control were, eye movement deficits in seven (39%), decrease in visual acuity in one (5.5%) and elevated IOP in one (5.5%) patient. Indirect CCF patients generally present with mild symptoms and the diagnosis may be overlooked. Mild progressive ophthalmoparesis with conjunctival hyperemia must be warning. Though rare bilateral CCF can be detected as well as unilateral CCF with bilateral findings.

Lesions affecting the body of the optic chiasm typically produce bitemporal hemianopia. The blood supply comes from the anterior communicating artery, anterior cerebral, posterior communicating, posterior cerebral, and basilar arteries. We herein report a young patient admitted to the emergency department with acute confusion, left-sided hemiparesis, hemihypoesthesia, and dysarthria. Bitemporal hemianopia was detected after resolution of confusion. On cranial magnetic resonance imaging (MRI), infarction in the right anterolateral thalamus in the territory of tuberothalamic artery (TA) and in posterior chiasma in the territory of the posterior communicating artery (PCoA) was revealed. Cerebral MR angiography showed luminal irregularity of the PCoA. The patient was presented to draw attention to the rare entity ischemic chiasmal syndrome.

BACKGROUND AND PURPOSE: Acute vestibular syndrome (AVS) is a common cause of emergency admittance and has very rarely been reported due to a vestibular nucleus infarction. Initial magnetic resonance imaging studies (MRIs) including diffusion-weighted images may reveal normal results and even bedside examination tests like HINTS battery which involves head impulse test (HIT), nystagmus and test of skew can be challenging in differing a peripheral vestibulopathy from a central lesion. METHODS: Four patients seen in the emergency department with AVS and evaluated with HINTS battery, cervical vestibular-evoked myogenic potentials (cVEMP) and cranial MRI revealing infarcts restricted to vestibular nuclei were evaluated. RESULTS: In two patients spontaneous nystagmus beating towards the unaffected side was present. In one patient spontaneous nystagmus changed direction on looking to the affected side. In the fourth gaze evoked nystagmus was present without any spontaneous nystagmus. In all, HIT was positive to the affected side. In three cVEMPs was studied revealing delayed latency, reduced amplitude p13/n23 potentials on the lesioned side in two of them. Initial MRIs including diffusion-weighted images disclosed acute infarction in the area of the vestibular nuclei in two patients, with normal results in the other two. Follow-up MRI's performed 48 hours later revealed vestibular nuclear infarction. CONCLUSION: It is not always easy to differentiate small lesions restricted to central vestibular structures from peripheral vestibular lesions both on clinical and radiological grounds. Follow-up cranial MRI is necessary in patients with known vascular risk factors.

OBJECTIVES: The importance and popularity of peripheral nerve block procedures have increased in the treatment of migraine. Greater occipital nerve (GON) block is a commonly used peripheral nerve block method, and there are numerous researches on its use in migraine treatment. MATERIALS AND METHODS: A search of PubMed for English-language randomized controlled trials (RCT) and open studies on greater occipital nerve block between 1995 and 2018 was performed using greater occipital nerve, headache, and migraine as keywords. RESULTS: In total, 242 potentially relevant PubMed studies were found. A sum of 228 of them which were non-English articles and reviews, case reports, letters and meta-analyses were excluded. The remaining articles were reviewed, and 14 clinical trials, seven of which were randomized-controlled on greater occipital nerve block in migraine patients, were identified and reviewed. CONCLUSIONS: Although clinicians commonly use greater occipital nerve block in migraine patients, the procedure has yet to be standardized. The present study reviewed the techniques, drugs and dosages, the frequency of administration, side effects, and efficacy of greater occipital nerve block in migraine patients.

PURPOSE: This study was planned to evaluate cognitive functions, especially attention and immediate recall, in children with childhood epilepsy with occipital paroxysms (CEOP), by using P300 and neuropsychological tests, which included visual and auditory number assays. Thirty patients with CEOP, ages ranging from 5 to 17 years were enrolled in the study. Twenty-five healthy children were taken as the control group. METHODS: Oddball paradigm was used in P300 recordings. The latency and the amplitude of the P300 wave recorded from Cz were taken into consideration. The neuropsychological test battery included visual and auditory number assays. RESULTS: P300 latency was significantly longer in the CEOP group (p=0.014). The results of the visual and auditory number assay test showed significant decline in the patient group when compared with the normal controls. CONCLUSIONS: Attention and immediate recall deficits as well as prolonged P300 latencies in children with CEOP can be due to an ongoing epileptic activity either influencing the whole brain or only the occipital lobe which can also be involved in the neuropsychological organization of the human cortex. Therefore, children with CEOP should be evaluated with more detailed neuropsychological tests for possible cognitive deficits.

A 26-year-old right handed female was admitted to hospital with right homonymous hemianopia associated with alexia without agraphia. Her cranial magnetic resonance imaging and magnetic resonance angiography revealed a left occipital venous infarction due to thrombosis of the left transverse, sigmoid sinuses and the left internal jugulary vein. The underlying conditions were protein C and protein S deficiency associated with the use of oral contraceptives. To our knowledge, alexia without agraphia has never been described due to a venous infarction associated with hereditary thrombophilia in the literature.

BACKGROUND AND PURPOSE: The clinical, etiological and stroke mechanisms are defined well before but the detailed clinical and etiologic mechanisms regarding to all clinical spectrum of posterior inferior cerebellar artery (PICA) infarcts were not systematically studied by diffusion-weighted imaging (DWI). METHODS: Seventy-four patients with PICA territory ischemic lesion proved by DWI with decreased apparent diffusion coefficient and FLAIR (fluid attenuation inversion recovery) included in our Registry, corresponding to 2% of 3,650 patients with ischemic stroke, were studied. The presence of steno-occlusive lesions in the posterior circulation were sought by magnetic resonance angiography, and reviewed with a three-dimensional rotating cineangiographic method. RESULTS: We found six subgroups of PICA territory infarcts according clinico-topographical relationship: (1) 9 patients with lesion in the territory lateral branch of PICA; (2) 23 patients with an infarct in the territory of medial branch of PICA; (3) 9 patients with a lesion involving both medial and lateral branches of the PICA; (4) 9 patients with cortical infarcts at the boundary zones either between medial and lateral branches of the PICA or between PICA and m/l superior cerebellar artery (SCA); (5) 10 patients with a lesion at the deep boundary zones either between medial and lateral PICA, or between PICA and medial/lateral SCA; (6)14 patients with concomitant multiple lesions in the PICA and in other vertebrobasilar artery territories. The main cause of PICA infarcts was extracranial large-artery disease in 30 patients (41%) patients, cardioembolism and in situ branch disease in 15 patients (20%) each. CONCLUSIONS: Multiple PICA territory lesions on DWI were not uncommon and could be caused by multiple emboli originating from break-up of atherosclerotic plaque in the subclavian/innominate-vertebral arterial system. DWI findings of single or multiple small lesions could account for some cases with transient and subtle cerebellar symptoms which have been considered before as 'vertebrobasilar insufficiency' without morphologic lesion. Different clinical-DWI correlations allow us to determine better definition of the topographical and etiological spectrum of acute PICA territory lesions, which was previously defined by pathological and conventional MRI studies.

BACKGROUND AND PURPOSE: Infarcts in the territory of superior cerebellar artery (SCA) are uncommon. The clinical, and etiological mechanisms of different infarct patterns of SCA are not well known. Diffusion-weighted imaging (DWI) is superior to conventional magnetic resonance imaging for detecting acute small and multiple ischemic lesions. METHODS: We studied 60 patients with lesions involving SCA territory proved by DWI, which have been selected from 3,800 patients with first ischemic stroke consecutively admitted to our stroke unit over a period of 5 years. RESULTS: There are 7 distinctive SCA lesion patterns: (1) a lesion was found in the medial (m) branch territory of SCA (mSCA) in 14 patients; (2) a lesion in the lateral (l) branch territory of SCA (lSCA) was seen in 9 patients; (3) a coexisting lesion involving mSCA and lSCA was found in 9 patients; (4) a lesion in cortical borderzones between SCA and m/l branches of the posterior inferior cerebellar artery (PICA) was observed in 6 patients; (5) a lesion in deep borderzones between lSCA and mSCA, and lPICA and mPICA was present in 8 patients; (6) a lesion involving the medial rostral cerebellum between the right and left SCA was found in 4 patients; (7) multiple lesions involving SCA and other vertebrobasilar artery territories were present in 10 patients. The main cause was possible artery-to-artery embolism from atherosclerotic vertebrobasilar arteries to distal branches of SCA in 20 patients (33%). Fourteen patients had a source of cardioembolism (23%), and 6 patients (8%) had concomitant atherosclerotic vertebrobasilar artery disease and a source of cardioembolism. CONCLUSIONS: An acute ischemic lesion in the SCA territory is mainly multiple. The lSCA territory was the most involved area. Small territorial infarcts were frequently associated with large territorial SCA infarcts. Borderzone SCA infarcts occurred in one third of the patients with transient benign symptoms. Mass effects are unusual despite the large amount of SCA involvement. Our results supported the fact that embolism is the predominant stroke mechanism in the SCA territory infarction.
