Abstract
"Reversible cerebral vasoconstriction syndrome" (RCVS) is a recently described entity that is mainly characterized by the association of severe ("thunderclap") headaches with or without additional neurological symptoms and diffuse, multifocal, segmental narrowings involving large and medium-sized cerebral arteries. By definition, angiographic abnormalities disappear within 3 months. The clinical course is usually benign, with a higher prevalence in young women. RCVS is idiopathic in the majority of the cases. However, recent papers have outlined the role of precipitating factors, including the use of vasoactive substances. Some patients, nevertheless, have a more severe clinical course with transient or permanent ischemic events. Hemorrhagic complications appear to have been underestimated. They are usually restricted to circumscribed cortical subarachnoid hemorrhage, in the absence of any ruptured cerebral aneurysm. This limited bleeding is unlikely at the origin of the diffuse vasoconstriction. The finding of an unruptured cerebral aneurysm in RCVS patients is probably incidental. An overlap is possible between RCVS and other syndromes such as posterior reversible encephalopathy syndrome. There is no standardized treatment regimen for RCVS patients. It appears rational to further investigate the efficacy and safety of the calcium-channel antagonist nimodipine.

Abstract
While primary angiitis of the central system (PACNS) remains a rare entity, the poor specificity of the available diagnostic tests and its multiple mimics create a major diagnostic challenge. Recently, there have been advances in understanding PACNS and differentiating it from its mimics. A recent breakthrough is the proposal of reversible cerebral vasoconstriction syndromes (RCVS) as a unifying concept for a group of disorders that highly mimics PACNS. RCVS are characterised by acute-onset, recurrent headaches, with or without additional neurologic events, with reversible vasoconstriction of the central nervous system (CNS) vasculatures, mimicking CNS vasculitis. RCVS are considered the most common mimics of PACNS. Advances in our understanding of RCVS have allowed for identification of patients previously confused with PACNS. The scope of this article focusses on the work-up, differential diagnosis and evaluation of PACNS, as well as a discussion of the secondary CNS vasculitides with emphasis on their clinical findings, diagnoses and treatment.

Abstract
OBJECTIVE To define the clinical characteristics and outcome of patients with idiopathic stenosis or occlusion of the basal arteries, without moyamoya collateral vessel formation. METHODS We identified patients who presented to our institution from 1996 to 2005 with occlusive disease of the distal internal carotid artery or the proximal middle or anterior cerebral arteries demonstrated by digital subtraction cerebral angiography. We excluded those with evidence of atherosclerotic disease, systemic vasculitis, moyamoya phenomenon, or any other condition that could otherwise explain their arterial occlusive disease. Medical records were reviewed for presenting symptoms and clinical characteristics. Outcome was determined from chart review and phone interviews. RESULTS Twelve patients were identified. All presented with transient ischemic attack or stroke. Eleven were women. Age at presentation ranged from 34 to 71 years. Nine had a history of hypertension; 5 had unilateral intracranial disease. Recurrent stroke on medical therapy occurred in none of the 5 during an average follow-up of 29 months. Seven had bilateral disease. Ischemic stroke occurred between 2 and 107 months after the initial event in 5 of 8 medically treated hemispheres. Moyamoya collateral vessels developed in 1 patient as shown on follow-up angiography. CONCLUSION The clinical features and outcome of these patients are similar to those reported in large case series of North American patients with moyamoya phenomenon. These data suggest a common etiology for the basal arterial occlusive process and a variable ability to form moyamoya collateral vessels.

Abstract
A 32-year-old man with a residual spastic quadriparesis from a traumatic C5-C6 fracture experienced a severe thunderclap headache. The medical history revealed an episode of autonomic dysreflexia (AD) due to neurogenic bladder/urinary tract infection (UTI). Blood pressure monitoring at admission revealed hypertension; blood pressure reaching 160/100 mmHg (average blood pressure in these patients and also in this patient being 90/60 mmHg). CT scan of the head, cerebrospinal fluid examination, CT angiography and MR angiography of the brain vessels were normal. Another UTI and a subsequent spell of AD were diagnosed. The patient continued to experience recurrent thunderclap headaches. Selective catheter cerebral angiography revealed multiple calibre changes in the intracranial blood vessels. A diagnosis of reversible cerebral vasoconstriction syndrome (RCVS) due to AD was considered. A magnetic resonance imaging (MRI) of the brain after 2 weeks revealed ischaemic changes in the left hemisphere. Follow-up brain MRI after 3 weeks showed reduction in size of the ischaemic changes, and catheter angiography after 6 weeks demonstrated improvement/normalization. A diagnosis of RCVS could be established. Repeated MRI/CT of the brain after 6 months demonstrated a large infarction in the left hemisphere. RCVS has been reported to occur in various clinical settings. It can occur in the setting of AD in patients with traumatic cervical cord injury. Prompt recognition of RCVS may be of vital importance to avoid further morbidity in patients with spinal cord injury.

Abstract
Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by recurrent thunderclap headaches and reversible cerebral vasoconstrictions. RCVS is more common than previously thought and should be differentiated from aneurismal subarachnoid hemorrhage. RCVS can be spontaneous or evoked by pregnancy or exposure to vasoactive substances. Patients tend to be middle-aged women but pediatric patients have been seen. Up to 80% of sufferers have identifiable triggers. Thunderclap headaches tend to recur daily and last for a period of around 2 weeks, while the vasoconstrictions may last for months. About one-third of patients have blood pressure surges accompanying headache attacks. The potential complications of RCVS include posterior reversible encephalopathy syndrome, ischemic strokes over watershed zones, cortical subarachnoid hemorrhage and intracerebral hemorrhage. Magnetic resonance images including angiography and venography and lumbar punctures are the studies of choice, whereas catheter angiography should not be implemented routinely. Patients with a mean flow velocity of the middle cerebral artery greater than 120 cm/s shown by transcranial color-coded sonography have a greater risk of ischemic complications than those without. The pathophysiology of RCVS remains unknown; sympathetic hyperactivity may play a role. Open-label trials showed calcium channel blockers, such as nimodipine may be an effective treatment in prevention of thunderclap headache attacks. In severe cases, intra-arterial therapy may be considered. Most patients with RCVS recover without sequelae; however, relapse has been reported in a small proportion of patients.

Abstract
Objectives: To study the clinical profiles, imaging findings and outcomes and field test the diagnostic criteria proposed by the International Classification of Headache Disorders, 2nd edition (ICHD-II) in patients with headache associated with sexual activity (HSA). Methods: We recruited 30 patients (16 men, 14 women, mean age at onset 40.2 ± 10.0 years) with headache associated with sexual activity at a headache clinic from 2004 to 2009. None of the patients had neurological deficits at onset. Results: Twenty patients (67%) had secondary causes, including one subarachnoid hemorrhage, one basilar artery dissection, and 18 cases reversible cerebral vasoconstriction syndrome (RCVS). Ten patients (33%) had primary HSA. The demographics, headache profiles, drug response and clinical course were similar between primary and secondary HSA. Compared to prior studies done in Western societies, our patients had similar clinical features but with a higher ratio of females (50%) and a higher frequency of chronic course (39%). Discussion: Sixty-seven percent of patients with RCVS could not fulfill the criteria of reversible angiopathy of the central nervous system (Code 6.7.3) proposed by the ICHD-II. The most common reason was headache resolution in more than two months. In addition, 40% of patients with primary HSA could not fulfill the ICHD-II criteria for primary HSA (Code 4.4). Conclusions: Our study found that intracranial vascular disorders were very common in patients with HSA. Thorough neurovascular imaging is required for all patients with HSA.

Abstract
OBJECTIVE To identify patterns of clinical presentation, imaging findings, and etiologies in a cohort of hospitalized patients with localized nontraumatic convexal subarachnoid hemorrhage. METHODS Twenty-nine consecutive patients with atraumatic convexal subarachnoid hemorrhage were identified using International Classification of Diseases-9 code from 460 patients with subarachnoid hemorrhage evaluated at our institution over a course of 5 years. Retrospective review of patient medical records, neuroimaging studies, and follow-up data was performed. RESULTS There were 16 women and 13 men between the ages of 29 and 87 years. Two common patterns of presentations were observed. The most frequent presenting symptom in patients < or =60 years (n = 16) was a severe headache (n = 12; 75%) of abrupt onset (n = 9; 56%) with arterial narrowing on conventional angiograms in 4 patients; 10 (p = 0.003) were presumptively diagnosed with a primary vasoconstriction syndrome. Patients >60 years (n = 13) usually had temporary sensory or motor symptoms (n = 7; 54%); brain MRI scans in these patients showed evidence of leukoaraiosis and/or hemispheric microbleeds and superficial siderosis (n = 9; 69%), compatible with amyloid angiopathy (n = 10; p < 0.0001). In a small group of patients, the presentation was more varied and included lethargy, fever, and confusion. Four patients older than 60 years had recurrent intracerebral hemorrhages in the follow-up period with 2 fatalities. CONCLUSION Convexal subarachnoid hemorrhage is an important subtype of nonaneurysmal subarachnoid bleeding with diverse etiologies, though a reversible vasoconstriction syndrome appears to be a common cause in patients 60 years or younger whereas amyloid angiopathy is frequent in patients over 60. These observations require confirmation in future studies.

Abstract
We report two patients with reversible cerebral vasoconstriction syndrome (RCVS) and carotid glomus tumour. The first patient presented with multiple thunderclap headaches. Cervical and cerebral magnetic resonance imaging showed diffuse cerebral vasoconstriction on magnetic resonance angiogram (MRA) and a carotid glomus tumour. The second patient presented with a cervical mass and was diagnosed with a non-secreting paraganglioma of the carotid body. Surgery with pre-operative angiography was followed by thunderclap headaches and MRA showed segmental cerebral vasoconstriction. Both patients were treated with nimodipine and headaches stopped. Both had normal cerebral arteries on the control MRA at 3 months. These two cases suggest that a paraganglioma may increase the susceptibility to develop RCVS. As a consequence, patients with RCVS should be investigated for a carotid glomus tumour, and patients with paraganglioma reporting severe headaches should have a cerebral MRA in order to rule out cerebral vasoconstriction.

Abstract
Thunderclap headache, a severe headache which is maximal in intensity at onset, is associated with numerous underlying disorders, including subarachnoid hemorrhage, unruptured intracranial aneurysm, cervical artery dissection, cerebral venous sinus thrombosis, stroke, intracranial hemorrhage, reversible cerebral vasoconstriction syndrome, and reversible posterior leukoencephalopathy. After exclusion of all possible causes, thunderclap headache may be considered a primary headache. This review summarizes the diagnostic considerations and clinical approach to thunderclap headache, with particular emphasis on the reversible cerebral vasoconstriction syndromes.

Abstract
We describe a 23-year-old male patient who presented with spontaneous intermittent and increasing attacks of severe, left-sided thunderclap headache combined with rapidly progressive muscle weakness and dysphasia, including gradual loss of consciousness. Subsequent CT, MRI and DSA showed progressive brain ischaemia and oedema within the left cerebral hemisphere with strict ipsilateral segmental arterial vasoconstriction. Despite extensive medical care, including steroids, the patient deteriorated rapidly. However, the clinical course changed dramatically within 15 h after the start of an intravenous infusion of prostacyclin at a dose of 0.9 ng/kg/min, with an almost complete recovery of consciousness and speech. In addition the pathophysiological alterations seen on magnetic resonance (imaging and digital) subtraction angiography including diffusion-weighted imaging and apparent diffusion coefficient maps shortly before prostacyclin treatment were clearly reduced when the patient was examined 3–4 days later and he continued to recover thereafter. Although not fully compatible, our case had several clinical characteristics and radiological findings reminiscent of those of the ‘segmental reversible vasoconstriction syndrome’, sometimes called the Call–Fleming syndrome.

Abstract
Reversible cerebral vasoconstriction is a rare and poorly understood syndrome, without clear diagnostic criteria. It has been described in association with multiple disorders, but has only been reported rarely in the setting of carotid artery dissection and, to our knowledge, never before in association with renal artery stenosis.

The headache syndrome and angiographic findings resolved after starting low-dose verapamil. Perhaps, some cases of primary exertional and primary headaches associated with sexual activity are associated with reversible cerebral vasoconstriction responsive to calcium channel blockers.

Abstract
Our aim was to review the etiologic background of isolated acute nontraumatic cSAH. While SAH located in the basal cisterns originates from a ruptured aneurysm in approximately 85% of cases, a broad spectrum of vascular and even nonvascular pathologies can cause acute nontraumatic SAH along the convexity. Arteriovenous malformations or fistulas, cortical venous and/or dural sinus thrombosis, and distal and proximal arteriopathies (RCVS, vasculitides, mycotic aneurysms, Moyamoya, or severe atherosclerotic carotid disease) should be sought by noninvasive imaging methods or/and conventional angiography. Additionally, PRES may also be a source of acute cSAH. In elderly patients, cSAH might be attributed to CAA if numerous hemorrhages are demonstrated by GRE T2 images. Finally, cSAH is rarely observed in nonvascular disorders, such as abscess and primitive or secondary brain tumors.

Abstract
A 39-year-old man with multiple sclerosis was admitted to the Neurological department because of sudden and intense headache, photophobia, nausea and vomiting. A subarachnoidal haemorrhage was suspected and cerebral CT scanning showed small amounts of subarachnoidal blood distributed symmetrically over both cerebral hemispheres - an unusual location for aneurismal bleeding. Liquor analysis revealed erythrocytes, positive bilirubin and slightly elevated protein. Subsequent cerebral MRI showed no signs of aneurysm, vascular malformation, venous sinus thrombosis or infarction. An intraarterial cerebral angiography was then performed and showed bilateral widespread segmental vasoconstriction in the anterior, middle and posterior cerebral arteries. A diagnostic workup on systemic vasculitis was negative. The patient's good general condition in spite of extensive angiographic findings rendered the diagnosis cerebral vasculitis unlikely. A state of reversible cerebral segmental vasoconstriction was suspected and the patient was treated with the calcium antagonist nifedipine and observed for four weeks. Cerebral angiography was then repeated and found to be normal. This case report highlights a less recognized and probably underdiagnosed cause of subarachnoidal bleeding.

Abstract
Reversible cerebral vasoconstriction syndrome (RCVS) is more frequent than previously thought and is probably underdiagnosed. The mean age of onset is 42 years, and it affects slightly more women than men. RCVS is attributed to a transient, reversible dysregulation of cerebral vascular tone, which leads to multifocal arterial constriction and dilation. More than half the cases (60%) are secondary to exposure to vasoactive substances (e.g., cannabis, antidepressants, and nasal decongestants) or occur in the postpartum period. RCVS has a characteristic clinical and radiological course, developing in a single phase after a sudden onset, and there is generally no new event after 1 month. The main pattern of presentation begins with recurrent thunderclap headaches, often triggered by sexual activity or various Valsalva's maneuvers, over a period of 1 to 3 weeks. Seizures and focal neurological deficits are less frequent and generally start after the headaches. Cortical subarachnoid hemorrhage (22%), intracerebral hemorrhage (6%), seizures (3%), and reversible posterior leukoencephalopathy (9%) are early complications, occurring mainly within the first week. Ischemic events, including TIAs (16%) and cerebral infarction (4%), occur significantly later than hemorrhagic strokes, mainly during the second week. Diagnosis requires the demonstration of the characteristic "string and beads" on cerebral angiography and can be difficult, for 21% of patients have a normal initial magnetic resonance angiography (MRA) and 9% both a normal MRA and a normal transcranial Doppler. In these cases, the initial investigations must be repeated after a few days. The final diagnosis is made when a follow-up MRA shows resolution or at least marked improvement of the arterial abnormalities within 12 weeks. RCVS is sometimes associated with other large artery lesions of the head and neck, including dissections and unruptured aneurysms, especially during the postpartum period. Nimodipine is the treatment most often recommended. In our experience, it is not especially effective in severe RCVS. Relapses are possible but rare and have not yet been reported in prospective series. Although the exact pathophysiology remains speculative, strong recommendations against vasoactive substances appear prudent.

Abstract
PURPOSE To report clinical and imaging features of diffuse cerebral vasoconstriction and to discuss the role of non-invasive imaging modalities for the diagnosis and the follow-up. PATIENTS AND METHODS Retrospective study including 13 consecutive patients with a diffuse cerebral vasoconstriction. Evaluation of the sensitivity of Doppler US and magnetic resonance angiography for the diagnosis. RESULTS The diagnosis is based on the association of a thunderclap headache, declenching factors found in 50% of cases and of stenosis involving middle and small cerebra arteries. In some cases cerebral hemorrhage may be present. DISCUSSION Diffuse cerebral vasoconstriction is a rare cause of thunder clap headhache, which needs to exclude other causes such as subarchnoid hemorrhage from aneurysm rupture. Non contrast CT of the head, frequently normal, may be falsely reassuring. It is therefore necessary to further assess the cerebral arteries to exclude an aneurysm but also to detect the presence of stenoses that would suggest the diagnosis. Non-invasive imaging modalities (MRA and Doppler US) are favored for detection and follow-up of proximal lesions.

Abstract
In younger patients with stroke, cerebral vasculitis and hereditary small vessel diseases should be considered as important differential diagnoses. Since the clinical course of cerebral vasculitis is highly variable, diagnostic workup, which includes laboratory tests, CSF analysis, cranial magnetic resonance imaging and biopsy, is often challenging. Therapy should be initiated on an interdisciplinary basis and includes immunosuppressive induction and maintenance regimes. Hereditary small vessel diseases, e.g. CADASIL or Fabry's disease, can mimic clinical features of cerebral vasculitis. Their diagnosis which is based on family history, typical clinical features and genetic analysis often has implications for treatment and genetic counselling.

Abstract
Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by severe headaches, as well as vasoconstriction of cerebral arteries, which resolves spontaneously in one to three months. This condition has a moderate female preponderance. The mean age of onset is around 45 years. About 60% of the cases are secondary, mainly occurring during postpartum and/or after exposure to vasoactive substances. The main clinical presentation includes multiple recurrent thunderclap headaches over one to three weeks. The major complications of RCVS are localized cortical subarachnoid hemorrhages (cSAH) (20-25%) and parenchymal strokes (5-10%). Complications occur with different time courses: hemorrhages (cSAH and intracerebral hemorrhages), and posterior reversible encephalopathy syndrome are early events occurring during the first week, while ischemic events including TIAs and cerebral infarcts occur significantly later, during the second week. Diagnosis requires the demonstration of the "string and beads" aspect of cerebral arteries by a cerebral angiogram (MRA, CTA or conventional) and the demonstration of the complete or marked normalisation of arteries by a repeat angiogram performed within 12 weeks of onset. Treatment is based on nimodipine that seems to reduce thunderclap headaches within 48h. However, nimodipine has not proven any efficacy against the hemorrhagic and ischemic complications of RCVS. Relapses are possible but rare and have not been reported yet in prospective series. It seems appropriate to advise the patients to avoid sympathomimetic and serotoninergic substances.

Abstract
It is remarkable that migraine is a prominent part of the phenotype of several genetic vasculopathies, including cerebral autosomal dominant arteriopathy with subcortical infarcts and leucoencephalopathy (CADASIL), retinal vasculopathy with cerebral leukodystrophy (RVCL) and hereditary infantile hemiparessis, retinal arteriolar tortuosity and leukoencephalopahty (HIHRATL). The mechanisms by which these genetic vasculopathies give rise to migraine are still unclear. Common genetic susceptibility, increased susceptibility to cortical spreading depression (CSD) and vascular endothelial dysfunction are among the possible explanations. The relation between migraine and acquired vasculopathies such as ischaemic stroke and coronary heart disease has long been established, further supporting a role of the (cerebral) blood vessels in migraine. This review focuses on genetic and acquired vasculopathies associated with migraine. We speculate how genetic and acquired vascular mechanisms might be involved in migraine.

Abstract
Reversible cerebral vasoconstriction syndromes (RCVS) occur predominantly in middle-aged women. Only one child with RCVS has ever been reported. We report three boys (aged 10, 16 and 10 years) who had multiple thunderclap headaches, including one boy with bath-related attacks. None of them had secondary causes. All their magnetic resonance angiography demonstrated reversible cerebral vasoconstrictions of the major arteries with increased cerebral blood flow velocities on transcranial colour-coded sonography studies. Two of the three had hypertensive surges during headache attacks. None of the three boys had seizure, stroke or other neurological deficits. However, a left occipital subcortical lesion of unknown nature was noted in one boy. The efficacy of calcium channel blockers was variable in these three boys. This report suggests that, although rare, RCVS should be considered in paediatric patients if they present with a history of multiple attacks of thunderclap headache.

Abstract
This article reviews "other primary headaches," a classification of the International Headache Society that includes primary stabbing headaches, primary cough headache, primary exertional headache, primary headache associated with sexual activity, hypnic headache, primary thunderclap headache, and new daily persistent headache. Clinicians should be aware that these headaches may be symptomatic to structural lesions and therefore usually require careful neuroimaging evaluation.

Abstract
We describe two patients with thunderclap headaches due to reversible cerebral vasoconstriction syndrome (RCVS). The first patient illustrates multilobar intracerebral haemorrhages as an under-appreciated feature of RCVS, and the second illustrates recurrent thunderclap headache (presumed recurrent RCVS) after a long interval of 4 years. These cases demonstrate the spectrum of presentation of RCVS, a clinically under-recognized condition.

Abstract
Thunderclap headache (TCH) is a neurological emergency that warrants immediate and comprehensive diagnostic determination. When no pathology can be identified the condition is classified as primary TCH, which is considered benign and self-limiting. TCH has also been reported as the initial symptom of reversible cerebral vasoconstriction syndrome (RCVS), which subsumes a variety of conditions, inconsistently coined Call-Flemming syndrome, benign angiopathy of the central nervous system, drug-induced arteritis, or migrainous vasospasm. Serious complications such as borderline ischaemic stroke have been reported. Although no standardized treatment regime exists, one commonly described but unproven therapy is parenteral or oral application of the calcium channel blocker nimodipine. Here, we report on a case of RCVS, where a progressive course prompted intra-arterial application of nimodipine, which resolved vasoconstriction immediately. We discuss the use of intra-arterial nimodipine application as a potential emergency treatment for a complicated or treatment-refractory course of RCVS.

Abstract
Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by sudden-onset recurrent ‘thunderclap’ headaches with reversible multifocal narrowing of the cerebral arteries, often associated with focal neurological deficits from ischaemic or haemorrhagic stroke. It has been associated with exposure to vasoconstrictive drugs, pregnancy, migraine, and a variety of other conditions. Whereas the pathophysiology of RCVS remains unclear, changes in the levels of female hormones are considered important because RCVS predominantly affects women and is frequently associated with pregnancy. We report a patient with angiographically confirmed RCVS whose MRI showed reversible brain oedema, suggesting an overlap between RCVS and the reversible posterior leucoencephalopathy syndrome. The only identified risk factor was oral contraceptive pills started 1 month prior to onset, supporting a role for female reproductive hormones in precipitating this overlap syndrome.

Abstract
INTRODUCTION Postpartum cerebral angiopathy (PPA) is considered one of a diverse group of rare conditions termed "reversible cerebral vasoconstriction syndromes". Existing literature suggest considerable overlap in the manifestations of eclampsia and PPA. METHODS Retrospective case series review of PPA and eclampsia from a single neurosciences intensive care unit patient log identified over a consecutive 18-month period. A MEDLINE search (using OVID) of the English literature from 1950 through October 2008 was also performed. RESULTS Four patients who meet the obstetrical criteria for eclampsia and four patients whose clinical and radiographic features were consistent with PPA were identified. Twenty-eight patients with PPA were identified from the literature and showed significant clinical and radiographic overlap without cohort. CONCLUSION Given the overlapping clinical, laboratory, and radiographical features of eclampsia and PPA, it is probable they share a similar underlying pathophysiological mechanism and represent different clinical expressions of the same pregnancy-related disorder. The obstetrical definition of eclampsia may be to strict when applied in the neurosciences intensive care unit.

Abstract
Both isolated angiitis of the central nervous system (IAN) and bacterial endocarditis (BE) may present with similar clinical and auxiliary findings. The differentiation is extremely important because of the different treatment regimens. We compared the findings of six patients with biopsy-proven IAN with the data of six patients with BE. Patients with IAN were younger (27-62 years) and presented with multiple strokes (n = 4), intracerebral hemorrhage (n = 1), epileptic seizures (n = 2), or encephalopathy (n = 1). All IAN patients had pathologic cerebrospinal fluid (CSF) findings (pleocytosis n = 5; protein elevation n = 4), and angiography revealed multilocular stenoses in two cases while digital subtraction angiography was normal in four. BE patients (32-77 years) presented multiple (n = 3) or single ischemic strokes (n = 2) or encephalopathy and headache (n = 2). While all patients showed inflammatory serum findings (C-reactive protein n = 6, leucocytosis n = 4), CSF-pleocytosis was present in two cases only. Angiography revealed a vasculitic pattern in two patients. The diagnosis of BE was established based on transesophageal echocardiography and blood cultures. Leptomeningeal and brain biopsies performed in two cases were normal. Both IAN and BE may present multiple strokes and encephalopathy. The frequency of a vasculitic pattern in angiography is similar in both conditions. While inflammatory serum findings are the rule in BE, pathologic CSF findings were present in all IAN patients. Transesophageal echocardiography and blood cultures should be performed in order to diagnose or exclude BE. Without brain biopsy, immunosuppressive therapy may be dangerous in suspected IAN.
