Predictors of Good Functional Outcome in Patients with Tandem Occlusion After Revascularization Treatment: Single-Center Experience with 12-Month Follow-Up.

OBJECTIVE: The optimal management and procedural strategy for tandem occlusion (TO) in acute ischemic stroke are still unclear, as is the long-term outcome of these patients. The aim of this study was to evaluate predictors of good functional outcome in patients with TO through the analysis of demographics, clinical, and radiological data with a 1-year follow-up. METHODS: We collected data on 100 patients with TO who underwent revascularization treatments in our comprehensive stroke center. We divided patients into 2 groups: those with good functional outcome, defined as a modified Rankin Scale 0-2, and those with poor functional outcome, defined as a modified Rankin Scale 3-6 at 3, 6, and 12-month follow-up. Moreover, we investigated which variables were able to influence mortality. RESULTS: At multivariate analysis, endovascular treatment with mechanical thrombectomy combined with emergent cervical carotid artery stenting was an independent predictor of good functional outcome at 6 and 12 months (adjusted odds ratio [aOR] 4.3, confidence interval [CI] 1.49-12.31, P = 0.007) (aOR 3.5, CI 1.25-9.61, P = 0.017) and was associated with a lower rate of mortality at 3 and 6 months follow-up (aOR 0.14, CI 0.04-0.57, P = 0.006 and aOR 0.296, CI 0.97-0.902, P = 0.032, respectively). Furthermore, smoking habit was associated with a better outcome at 3-month follow-up (aOR 10.7, CI 2.2-51.6, P = 0.003) but not at 6- and 12-month. CONCLUSIONS: Our research, conducted in a small sample size of patients with acute ischemic stroke due to TO of anterior circulation, found that acute stent placement seems to be safe, improving clinical outcome, and it is associated with low rate of mortality at long-term follow-up.

Thrombectomy in ischemic stroke patients with tandem occlusion in the posterior versus anterior circulation.

BACKGROUND: Mechanical thrombectomy (MT) was found to be beneficial in acute ischemic stroke patients with anterior tandem occlusion (a-TO). Instead, little is known about the effectiveness of MT in stroke patients with posterior tandem occlusion (p-TO). We aimed to compare MT within 24 h from last known well time in ischemic stroke patients with p-TO versus a-TO. METHODS: We conducted a cohort study on prospectively collected data of patients registered in the Italian Registry of Endovascular Treatment in Acute Stroke (IRETAS) who were treated with MT within 24 h from last known well time for acute ischemic stroke with p-TO (n = 275) or a-TO (n = 1853). RESULTS: After adjustment for unbalanced pre-procedure variables (year 2015-2021, age, sex, NIHSS score, ASPECTS, and time strata for puncture groin) and pre-stroke mRS score as pre-defined predictor, p-TO was significantly associated with lower probability of mRS score 0-2 (OR 0.415, 95% CI 0.268-0.644) and with higher risk of death (OR 2.813, 95% CI 2.080-3.805) at 3 months. After adjustment for unbalanced procedural and post-procedure variables (IVT, general anesthesia, TICI 3, and 24-h HT) and pre-stroke mRS score as pre-defined predictor, association between p-TO and lower probability of mRS score 0-2 (OR 0.444, 95% CI 0.304-0.649) and association between p-TO and with higher risk of death (OR 2.971, 95% CI 1.993-4.429) remained significant. CONCLUSIONS: MT within 24 h from last known well time in ischemic stroke patients with p-TO versus a-TO was associated with worse outcomes at 3 months.

Characteristics and outcomes of cerebral venous thrombosis associated with COVID-19.

INTRODUCTION: Previous reports and meta-analyses derived from small case series reported a mortality rate of up to 40% in patients with coronavirus disease 2019 associated cerebral venous thrombosis (COVID-CVT). We assessed the clinical characteristics and outcomes in an international cohort of patients with COVID-CVT. PATIENTS AND METHODS: This was a registry study of consecutive COVID-CVT patients diagnosed between March 2020 and March 2023. Data collected by the International Cerebral Venous Thrombosis Consortium from patients with CVT diagnosed between 2017 and 2018 served as a comparison. Outcome analyses were adjusted for age and sex. RESULTS: We included 70 patients with COVID-CVT from 23 hospitals in 15 countries and 206 controls from 14 hospitals in 13 countries. The proportion of women was smaller in the COVID-CVT group (50% vs 68%, p < 0.01). A higher proportion of COVID-CVT patients presented with altered mental state (44% vs 25%, p < 0.01), the median thrombus load was higher in COVID-CVT patients (3 [IQR 2-4] vs 2 [1-3], p < 0.01) and the length of hospital stay was longer compared to controls (11 days [IQR 7-20] vs 8 [4-15], p = 0.02). In-hospital mortality did not differ (5/67 [7%, 95% CI 3-16] vs 7/206 [3%, 2-7], aOR 2.6 [95% CI 0.7-9]), nor did the frequency of functional independence after 6 months (modified Rankin Scale 0-2; 45/58 [78%, 95% CI 65-86] vs 161/185 [87%, 81-91], aOR 0.5 [95% CI 0.2-1.02]). CONCLUSION: In contrast to previous studies, the in-hospital mortality rate and functional outcomes during follow-up did not differ between COVID-CVT patients and the pre-COVID-19 controls.

The Telltale Botox: Botulinum Toxin Injection by an Expert Hand as an Intracranial Aneurysm Detector.

Complications in aesthetic medicine can be considered a consequence of the inexperience of the performing physician, but in some cases, they can unveil far more serious conditions, hitherto silent. We present a case of a 48-year-old patient who, following botulinum toxin type A (Botox) injection for treatment of forehead wrinkles, returned to our attention 12 days later for a discrete, newly onset right eyelid ptosis. This ptosis was a telltale sign of the presence of an intracranial aneurysm closely related with the oculomotor nerve. The lack of compensatory action by the frontalis muscle in maintaining the eyelid in position allowed us to highlight the extrinsic compression deficit of the oculomotor nerve. Subsequently, the patient underwent endovascular treatment of the aneurysm, leading to complete resolution of the case.

Factors associated with hemorrhagic transformation after endovascular treatment despite early recanalization.

PURPOSE: To identify new factors associated with hemorrhagic transformation (HT) despite early recanalization in patients with acute ischemic stroke treated with mechanical thrombectomy. METHODS: We retrospectively included patients with known onset of large vessel occlusion treated with mechanical thrombectomy +/- intravenous thrombolysis. Non-contrast CT was performed at 24 +/- 12 h from endovascular procedure. We collected data on patient characteristics, risk factors, radiological and treatment features, stroke severity on admission and discharge, carotid intima-media thickness (CIMT), Neutrophils-to-Lymphocytes ratio (NLR), white matter hyperintensities measured according to the Fazekas score on FLAIR MRI data. The main outcome measures were the incidence of HT and factors associated with it. Secondary outcome measures were symptomatic intracerebral hemorrhage and parenchymal hematoma. RESULTS: Of 874 patients, 472 met the inclusion criteria, 211 (44.7%) had HT. Factors significantly associated with increased risk of HT included onset-to-recanalization time, CIMT (normal/mild), ASPECT-MRI < 6, and a higher NLR. We found that beyond 7.67 h from onset-to-recanalization, the risk of HT increases and exceeds 50%. ASPECT-MRI, NLR, and CIMT independently predict HT despite early recanalization. CONCLUSIONS: We identified novel factors associated with HT in patients with acute ischemic stroke of known onset treated with mechanical thrombectomy. We found that at 7.67 h from onset to recanalization, the risk of HT is >50%, and we identified factors responsible for HT despite early recanalization.

Prevalence, clinical features, and radiological pattern of artery of Percheron infarction: a challenging diagnosis.

PURPOSE: Occlusion of artery of Percheron (AOP), a rare variant of paramedian branches of posterior cerebral artery, results in a characteristic pattern of ischemic lesions in bilateral paramedian thalami with or without midbrain and anterior thalami involvement. AIM: To evaluate the prevalence, the clinical, and the imaging features of AOP infarction in a single comprehensive stroke center experience. METHODS: We retrospectively search in our stroke center database, patients with ischemic lesions in the AOP distribution. We collected clinical features and time between hospital admission and diagnosis. Imaging findings were categorized following a pre-selected classification. RESULTS: Of 2830 ischemic stroke admitted in our center, we identified 15 patients with AOP infarction (0.53%). Clinical manifestations were variable, but oculomotor disturbances, particularly vertical gaze palsy, were the most observed, followed by consciousness impairment, varying from drowsiness to coma. The most frequent imaging pattern was bilateral paramedian thalamic infarction with midbrain infarction, and the V-sign was recognized in 6 cases from this group. In 8 patients a fetal origin of the PCA was observed. The average time from first hospital admission to diagnosis was 28.09 h. CONCLUSIONS: The prevalence of AOP infarction in our center was 0.53%. Diagnosis of AOP infarction can be challenging and should be suspected in case of sudden altered consciousness.

Sleep and sleep-modifying factors in chronic migraine patients during the COVID-19 lockdown.

AIMS: The objective of the present study was to evaluate sleep features and sleep-modifying factors in patients with chronic migraine (CM) during the first Italian COVID-19 lockdown. MATERIAL AND METHODS: The study was based on an e-mail survey addressed to CM patients of our headache center. The survey investigated demographic, life-style, sleep, psychological, and migraine features during the first COVID-19 lockdown period and the month before. The outcomes were sleep quality (measured using PSQI) and variation in sleep quality, duration, and latency. RESULTS: Ninety-two patients were included. The mean PSQI was 11.96. Sleep quality was improved in 14.1%, stable in 47.8%, and worsened in 38.0%. Sleep latency was reduced in 5.4%, stable in 46.7%, and increased in 47.8%. Sleep duration was reduced in 29.3%, stable in 34.8%, and increased in 35.9%. Significant associations were found with age, work/study, remote working, job loss, meal quality change, smoking variation, COVID-19 province prevalence, home-inhabitant relationship, ratio of house size/number of people, stress, state anxiety, anxiety/depression variation, future concern variation, computer hours, internet hours, and television hours. CONCLUSION: The study described sleep features of chronic migraineurs during COVID-19 lockdown, pinpointing the main factors involved in sleep quality and sleep changes. Our findings revealed that migraineurs' sleep was closely linked with life-style and psychological features. Several modifiable factors came to light and they should be considered in order to develop an optimal management of CM. An appropriate and more aware treatment of sleep problems could be a way to improve migraineurs' life.

Carotid free-floating thrombus during COVID-19 vaccine era: causality or not?

Carotid free-floating thrombus (FFT) is very rarely diagnosed in patients with acute ischemic stroke. It is a real clinical emergency due to the significant risk of death associated with thromboembolic complications. Herein, we present three patients with ischemic stroke caused by carotid FFT after less than 20 days from administration of mRNA vaccine BNT162b1 (Pfizer/BioNTech) for Severe Acute Respiratory Syndrome-CoronaVirus 2 (SARS-CoV-2). To our knowledge, these are the first cases reporting carotid FTT following SARS-CoV-2 vaccination.

Non-conducted premature atrial complexes: A new independent predictor of atrial fibrillation in cryptogenic stroke.

INTRODUCTION: Atrial fibrillation (AF) is the main cardiac cause of stroke, but it frequently remains undetected. In patients with cryptogenic stroke an Holter electrocardiogram (ECG) monitoring for AF is recommended. OBJECTIVE: To evaluate the prognostic role of Non-Conducted Premature Atrial Complexes (ncPACs) recorded on Holter ECG. METHODS: We prospectively enrolled consecutive patients admitted to the Stroke Unit of our hospital with a diagnosis of cryptogenic stroke between December 2018 and January 2020; all patients underwent 24-h Holter ECG monitoring during hospitalization. Two follow-up visits were scheduled, including a 24-h Holter ECG at 3 and 6 months to detect AF. RESULTS: Among 112 patients, 58% were male with an average age of 72.2 ± 12.2 years. At follow-up, AF was diagnosed in 21.4% of the population. The baseline 24-h Holter ECG burden of ncPACs and Premature Atrial Complexes (PACs) was higher in patients with AF detected on follow-up (13.5 vs 2, p = 0.001; 221.5 vs 52; p = 0.01). ROC analysis showed that ncPACs had the best diagnostic accuracy in predicting AF (AUC:0.80; 95% CI 0.68-0.92). Cut-off value of ≥7 for ncPACs burden showed the highest accuracy with sensitivity of 62.5% and specificity 97.7% to predict AF onset at follow-up. Moreover, at multivariate Cox-proportional hazard analysis ncPACs burden ≥7 was a powerful independent predictor of AF onset (HR 12.4; 95% CI 4.8-32.8; p < 0.0001). CONCLUSIONS: NcPACs burden ≥7 represents a new predictor of AF that could guide the screening of this arrhythmia in cryptogenic stroke patients.

Association of the careggi collateral score with radiological outcomes after thrombectomy for stroke with an occlusion of the middle cerebral artery.

We aimed to examine the association between Careggi Collateral Score (CCS) and radiological outcomes in a large multicenter cohort of patients receiving thrombectomy for stroke with occlusion of middle cerebral artery (MCA). We conducted a study on prospectively collected data from 1785 patients enrolled in the Italian Registry of Endovascular Treatment in Acute Stroke. According to the extension of the retrograde reperfusion in the cortical anterior cerebral artery-MCA territories, CCS ranges from 0 (absence of retrograde filling) to 4 (visualization of collaterals until the alar segment of the MCA). Radiological outcomes at 24 h were the presence and severity of infarct growth defined by the absolute change in ASPECTS from baseline to 24 h; presence and severity of cerebral bleeding defined as no ICH, HI-1, HI-2, PH-1, or PH-2; presence and severity of cerebral edema (CED) defined as no CED, CED-1, CED-2, or CED-3. Using CCS = 0 as reference, ORs of CCS grades were significantly associated in the direction of better radiological outcome on infarct growth (0.517 for CCS = 1, 0.413 for CCS = 2, 0.358 for CCS = 3, 0.236 for CCS = 4), cerebral bleeding grading (0.485 for CCS = 1, 0.445 for CCS = 2, 0.400 for CCS = 3, 0.379 for CCS = 4), and CED grading (0.734 for CCS = 1, 0.301 for CCS = 2, 0.295 for CCS = 3, 0.255 for CSS = 4) shift in ordinal regression analysis after adjustment for pre-defined variables (age, NIHSS score, ASPECTS, occlusion site, onset-to-groin puncture time, procedure time, and TICI score). Using CCS = 4 as reference, ORs of CCS grades were significantly associated in the direction of worse radiological outcome on infarct growth (1.521 for CCS = 3, 1.754 for CCS = 2, 2.193 for CCS = 1, 4.244 for CCS = 0), cerebral bleeding grading (2.498 for CCS = 0), and CED grading (1.365 for CCS = 2, 2.876 for CCS = 1, 3.916 for CCS = 0) shift. The CCS could improve the prognostic estimate of radiological outcomes in patients receiving thrombectomy for stroke with MCA occlusion.

Moyamoya Vasculopathy: Cause, Clinical Manifestations, Neuroradiologic Features, and Surgical Management.

In moyamoya disease, the progressive occlusion of the distal portion of the internal carotid artery and its major branches is typically responsible for the formation of an extensive network of collateral vessels at the base of the brain. When moyamoya collateral network develops in association with various systemic or acquired diseases, the term moyamoya syndrome is used to denote this phenomenon. Sudden changes in the supraclinoid internal carotid artery and middle cerebral artery can be recognized with noninvasive neurovascular imaging techniques, which also allow a differential diagnosis with similar diseases such as degenerative steno-occlusive disease, cerebral vasculitis, and twig-like middle cerebral artery. Once the diagnosis is established, the definitive treatment for moyamoya disease is surgical revascularization, with the goal of increasing cerebral blood flow and preventing recurrent stroke. We provide a comprehensive review of the clinical and radiologic features in moyamoya vasculopathy along with its surgical management.

Ischemic stroke and reperfusion therapies in diabetic patients.

INTRODUCTION: The study aimed to identify the main prognostic factors in diabetic patients with ischemic stroke undergoing reperfusion therapies (RT). METHODS: This retrospective study included 170 diabetic patients: 62 treated with intravenous thrombolysis (IVT) alone and 108 with mechanical thrombectomy (MT). Among MT patients, 29 underwent IVT. We collected clinical, laboratory, and radiological data. The outcomes were 3-month functional impairment (measured by modified Rankin scale, mRs), discharge neurological severity (measured by National Institutes of Health Stroke Scale score, NIHSS), 3-month mortality, intracranial hemorrhage (ICH), and symptomatic intracranial hemorrhage (SICH). We performed a general analysis for all RT and sub-group analyses for IVT and MT. RESULTS: A lower mRs was associated with lower glycemia and admission NIHSS (aNIHSS) in all RT and MT; lower aNIHSS and younger age in IVT. Mortality increased with hyperglycemia, aNIHSS, and age in all RT; age and aNIHSS in IVT; hyperglycemia and systolic pressure in MT. A lower discharge NIHSS was related with lower aNIHSS, thrombolysis, and no thrombectomy in all RT; lower aNIHSS in IVT; lower aNIHSS and thrombolysis in MT. ICH was associated with elevated aNIHSS, older age, and lower platelets in all RT; lower platelets and older age in IVT; higher aNIHSS in MT. SICH depended on longer thrombectomy duration in all RT; no metformin use in IVT; higher weight in MT. CONCLUSION: The study shed light on diabetic patients and stroke RT highlighting the protective effect of metformin in IVT and the role of glycemia, weight, and combined treatment in MT.

Repeated reperfusion treatment in recurrent ischemic stroke: A retrospective single-center case series.

Data regarding repeated reperfusion therapy (rRT) in acute ischemic stroke (AIS), including intravenous thrombolysis and endovascular treatment (EVT), are quite poor. To date, there are only few case reports and five larger studies on repeated EVT. We aimed to report our single-center experience and describe different clinical scenarios of recurrent AIS with emergent large vessel occlusion (LVO), for which the decision-making process could be challenging in the emergency setting. We retrospectively reviewed 765 consecutive AIS patients with LVO, who underwent reperfusion procedures at our comprehensive stroke center, from 2014 to 2020, and identified rRT patients. We identified and reviewed the medical records of eight patients (1.05%), who repeated reperfusive treatment for recurrent stroke within 30 days (early arterial reocclusion, EAR) and after 30 days (late arterial reocclusion, LAR). We assigned collected data to three clinical scenarios, each divided into EAR and LAR cases. All patients had recurrent emergent LVO in the same vessel territory previously affected, both in EAR and LAR patients. A good clinical outcome has been achieved in EAR patients (modified Rankin Score ≤ 2). Artery-to-artery embolic mechanism was more common in the EAR group, while LAR was more frequently associated with cardioembolic source. RRT appears to be an effective treatment option for recurrent LVO, and it should not be withheld in carefully selected patients. EVT should be considered, including aspiration-only and stenting procedures in patients with AIS and recurrent LVO after previous reperfusive treatments, even after a very short time.

Ischemic Stroke and Asymptomatic Pulmonary Opacities.

PURPOSE: Pulmonary opacities are described in many chest radiograph reports in stroke patients and are often asymptomatic. The aim of this study is to investigate the clinical features associated with asymptomatic pulmonary opacities (APO) and evaluate APO prognostic value in ischemic stroke. METHODS: We prospectively analyzed patients with acute ischemic stroke without pneumonia symptoms referred to our stroke center. All patients underwent a chest x-ray within 48 hours after admission. We divided patients with APO (defined as asymptomatic area of increased pulmonary attenuation) and patients without APO. Firstly, we compared clinical, laboratory, and echocardiographic parameters between groups; secondly, APO were evaluated as a possible predictor of the neurological severity at discharge and functional outcome at 90 days. RESULTS: We included 162 patients, 78 of whom had APO. On univariate analysis, we observed a significant difference between patients with APO and patients without APO in terms of neutrophils (73,56±10,10 vs 69,72±12,29; p=0,031), atrial fibrillation (AF, paroxysmal 27,4% vs 25,6%; permanent 19% vs 2,6%; p<0,002), cardioembolic etiology (37,2% vs 22,7%, p <0,033), thrombectomy (58,3% vs 42,9%, p <0,05), dysphagia/vomit (34,5% vs 14,10%, p<0,005), admission NIHSS (14,20±5,98 vs 10,29±5,82, p=0,001), discharge NIHSS (8,68±6,73 vs 5,64±6,20; p=0,003), and 90 days mRS (3,47±2,12 vs 2,31±1,93; p=0,001). On multivariate analysis, APO were significantly associated with admission NIHSS and AF. APO were a predictor of outcome on univariate analysis, but not on multivariate. CONCLUSION: APO in acute ischemic stroke are associated with AF. APO were not a predictor of neurological and functional outcome.

Vascular pattern and radiological follow up in a case of pontine warning syndrome.

Pontine warning syndrome (PWS) is a condition characterized by crescendo transient ischemic attacks due to pontine ischemia. The reported case described a 72-year-old woman who presented repetitive sudden episodes of double vision, impaired balance, slurred speech and right-sided weakness. Neurological deficits lasted a few minutes-hours and disappeared during the first seven days after onset. On the 1st day, MRI revealed acute left paramedian pontine infarction with focal swelling. Supra-aortic vessel imagining revealed bilateral internal carotid stenosis of 50%; hypoplasia of the left vertebral artery. On the 7th day, MRI showed a tissue swelling reduction, and from that day, she had no symptoms. These clinical and radiological features were suggestive of PWS. Our patient presented a particular vascular pattern that could favour symptoms fluctuation. We performed a close MRI follow up and it allowed us to observe a clinical stabilization in association with edema reduction.

Variants of the circle of Willis in ischemic stroke patients.

PURPOSE: We aim to provide prevalence and pattern of anatomical variants of circle of Willis in over one thousand ischemic stroke patients compared to an age- and sex-matched control group, and to determine their role in the severity and in-hospital prognosis. METHODS: Two groups of neuroradiologists evaluated all vascular images of ischemic stroke patients and controls to identify anatomical variants using a preexisted classification. We collected data concerning patient characteristics, stroke severity on admission and discharge, in-hospital mortality, hemorrhagic transformation, acute treatment performed, and etiology. RESULTS: We included 1131 patients with acute ischemic stroke and 562 controls. Among stroke patients, 702 (62.1%) had one or more vascular variants, compared to 308 (54.8%) of the control group (p < 0.01), 165/702 (23.5%) had an anterior circulation variant only, 384/702 (54.7%) had a posterior circulation variant only, and 153/702 (21.8%) patients had variants in both anterior and posterior circulation. Patients with variants were older (69.7 ± 13.9 years vs 72.0 ± 12.9 years; p = 0.039). The most prevalent variant was the agenesis/hypoplasia of the ACA (201/1131; 17.8%) followed by the unilateral fetal type of the PCA (137/1131; 12.11%). CONCLUSIONS: We provided the prevalence and the pattern of the brain vascular variants of the circle of Willis in a cohort of patients with ischemic stroke. The prevalence of variants was higher in stroke patients compared to controls. Patients with variants were older but had no differences in sex, neurological admission severity, hemorrhagic transformation, etiology, and in-hospital outcome compared to patients with a typical circle of Willis.

Minor stroke with bilateral acute infarctions and combined vascular anomalies: A complex case report.

We report the case of a patient with bilateral acute ischemic lesions (AIS) in middle cerebral artery (MCA) territory associated with an extremely rare combination of anomalies of the aortic arch and the left internal carotid artery (ICA). The diagnosis deposed for bilateral minor embolic stroke of undetermined source (ESUS), inpatient with patent foramen ovale (PFO) and positive antiphospholipid (aPL) test. To our knowledge, this is the first description of a patient with this rare combination of vascular anomalies.

Isolated Insular Stroke: Clinical Presentation.

The symptoms related to insular ischemia have been the object of several studies in patients affected by stroke, although they are often accompanied by other ischemic alteration of adjacent brain structures supplied by the middle cerebral artery (MCA). The insula is vulnerable because of an ischemia due to thromboembolic vascular occlusion of the M1 MCA segment and the 2 main MCA branches (M2), mainly when they abruptly arise from the principal stem at a right angle. This topographical and anatomical peculiarity could enable an embolic formation, especially due to atrial fibrillation (AF), to occlude the transition pathway between M1 and M2, while the proximal origin of vascular supply protects the insula from ischemia due to hemodynamic factors. The aim of the study is to characterize the clinical aspects of acute ischemic strokes as a first event in the insular territory with specific attention to atypical manifestation. We have considered 233 patients with a first event stroke involving the insular territory and 13 cases of isolated insular stroke (IIS), from the stroke registry of the Policlinico "G.Martino", University of Messina, between the February 10, 2014 and the February 7, 2018. IIS patients showed CT/MRI lesions restricted to the insular region. Exclusion criteria were coexisting neurological diseases, structural brain lesions, extension to the subinsular area >50% of the total infarct volume. We identified 13 IIS patients (mean age 74 years), with an isolated symptom or a combination of typical and atypical aspects. Furthermore, we observed high frequency detection of cardiac disturbances. To our knowledge, just a few previous studies have described IIS; their incidence is still not well defined. IIS manifested with a combination of deficits including motor, somatosensory, speaking, coordination, autonomic and cognitive disturbances. After an ischemic stroke, AF manifestation could follow briefly the major event and its duration could be very short, as an autonomic dysfunction due to an insular infarction. This clinical condition requires a continuous cardiac monitoring for this dangerous occurrence.

Recurrent intracranial hemorrhage and cerebral venous sinus thrombosis: an atypical case of Neuro-Behçet's Syndrome.

We report the case of a 22-year-old man with an history of headaches, seizures, cognitive impairment associated with recurrent intracranial hemorrhage (ICH), acute ischemic stroke (AIS), worsened over the last eighteen months for a new onset of uveitis and cerebral venous sinus thrombosis (CVST). After excluding common causes of lobar ICH, and some rare ones according to the diagnostic protocol proposed by Beuker et al, in the suspicion of Primary Angiitis of the Central Nervous System (PACNS), the gradual development of a low-grade fever, a cutaneous rash, and a papulopustular manifestation on lower back after rachicentesis (pathergy phenomenon), allowed us to make a diagnosis of Neuro-Behçet's Syndrome (NBS) without oral/genital aphthous ulcerations, according to the International Study Group for Behçet's Disease classification criteria for BD (ICBD).
