Reversible cerebral vasoconstrictionsyndrome (RCVS, sometimes called Call-Fleming syndrome) is a disease characterized by a weeks-long course of thunderclap headaches, sometimes focal neurologic signs, and occasionally seizures. (wikipedia.org)
Posterior reversible encephalopathy syndrome has a similar presentation, and is found in 10-38% of RCVS patients. (wikipedia.org)
We present a case of a female patient with reversible cerebral vasoconstrictionsyndrome (RCVS) arising after receiving subcutaneous injection of human placenta extract. (neurology-jp.org)
However, a recent study suggested that approximately 1 in every 20 patients hospitalized for posterior reversible encephalopathy syndrome (PRES) or reversible cerebral vasoconstrictionsyndrome (RCVS) were most likely misdiagnosed during their initial emergency department (ED) visit. (medscape.com)
Other underlying causes of sSAH, not diagnosed on MRI, were reversible cerebral vasoconstrictionsyndrome (RCVS) based on clinical criteria and conventional angiography (n = 4), angiitis diagnosed by skin biopsy (n = 1), vascular malformation diagnosed on CT and digital subtraction angiographies (n = 3), and overanticoagulation (n = 1).

They said that PRES and RCVS are rare, reversible conditions and highlighted that most patients fully recover if administered appropriate treatment. (healthwire.co)
Dr Chen's research interests focus on deciphering the pathophysiology of headache disorders, specifically, the clinical, neuroimaging, and molecular biological studies of reversible cerebral vasoconstrictionsyndrome (RCVS) as well as the animal models (especially cortical spreading depression) and genomics studies of migraine. (springerhealthcare.com)
Reversible cerebral vasoconstrictionsyndrome (RCVS) is characterized by sudden onset severe headache with or without focal neurologic deficits and is accompanied by segmental or multifocal intracranial arterial vasospasms that resolve within 3 months. (pfmjournal.org)
Since the feature of RCVS is a reversible cerebral arterial vasospasm, it can cause various brain lesions including subarachnoid hemorrhage, intracerebral hemorrhage, or posterior reversible encephalopathy syndrome, and even ischemic strokes [ 1 , 2 ]. (pfmjournal.org)
Introduction Reversible cerebral vasoconstriction syndromes (RCVS) have been documented to take place after an inciting event or illness. (bmj.com)
Physical examination, imaging and laboratory findings were descriptive of RCVS, and the patient's rapid recovery was consistent with the usual disease progression of a reversible vasculopathy. (bmj.com)
Conclusion A reversible cerebral vasoconstrictionsyndrome may occur in some circumstances after a hysterectomy with bilateral salpingo-oophorectomy. (bmj.com)
PRES and RCVS are rare cerebrovascular dysregulation syndromes that present with symptoms such as severe headaches, numbness, dizziness, and altered mental status, which may mimic other less serious ailments. (medscape.com)
Additionally, diagnosis of PRES/RCVS requires advanced neuroimaging, which might not be readily available in the ED," she added. (medscape.com)
The study analyzed data from 4633 patients with PRES, RCVS, or both across 11 states in the United States from 2016 to 2018. (medscape.com)
and the ED discharge occurred within 14 days before the patient's hospitalization for PRES or RCVS. (medscape.com)
Perhaps in patients with a headache disorder, providers are misinterpreting PRES/RCVS symptoms as related to the known headache disorders, leading to a cognitive error (anchoring bias). (medscape.com)
These findings highlight the challenges of diagnosing rare cerebrovascular conditions, such as PRES and RCVS, especially in the fast-paced ED environment. (medscape.com)
Providers should be sure to ask patients with headache complaints in the ED about red flag features and remember to consider PRES/RCVS when evaluating these patients as well as those with substance use disorders and neurological symptoms," said Liberman. (medscape.com)
CAA, RCVS and PRES represented more than 50% of the etiological mechanisms. (bordeaux-neurocampus.fr)
In the vast majority of cases of PRES and RCVS, patients recover from their symptoms. (bigpharmanews.com)
Subarachnoid hemorrhage and cerebral2
Vasospasm is common post subarachnoid hemorrhage and cerebral aneurysm, but in RCVS only 25% of patients have symptoms post subarachnoid hemorrhage. (wikipedia.org)
After ruling out the common causes, including subarachnoid hemorrhage and cerebral vasculitis , neurologists should consider RCVS in the differential diagnosis of thunderclap headaches in those with a history of ingestion of vasoactive substances like hot chili peppers," he said. (medscape.com)
1 , 2 The diagnosis of RCVS needs a high level of clinical suspicion. (researchsquare.com)
Prompt diagnosis and treatment are vitally important because RCVS may progress to encephalopathy, cerebral infarction and hemorrhage. (researchsquare.com)
1 , 2 Although brain MRA is a useful diagnostic modality 3 , CT angiography was initially performed in this case since temporary epicardial pacing leads were placed after surgery, which led to the diagnosis of the RCVS. (researchsquare.com)
HR-MRI can be helpful in direct visualization of the vasoconstriction of RCVS and differential diagnosis of other diseases, possibly even without serial examinations. (pfmjournal.org)
Thus, the diagnosis of RCVS should not be discarded based on the absence of thunderclap headache [ 8 ]. (pfmjournal.org)
The differential diagnosis includes primary angiitis of the central nervous system (PACNS) but one major clinical difference is that the symptoms of RCVS usually resolve within days or weeks whereas PACNS is often fatal. (bmj.com)
Symptom3
The key symptom of RCVS is recurrent thunderclap headaches, which over 95% of patients experience. (wikipedia.org)
A severe headache known as a 'thunderclap' is the main symptom of RCVS and may be the only one. (bigpharmanews.com)
It has been demonstrated that thunderclap headache is usually the initial symptom of RCVS. (pfmjournal.org)
Stroke2
Less than 5% of patients experience progressive vasoconstriction, which can lead to stroke, progressive cerebral edema, or even death. (wikipedia.org)
Calcium channel blockers have been reported to be effective in relieving the symptoms 1 , 2 , but their impact on cerebral vasoconstriction or stroke severity remains unclear. (researchsquare.com)
Symptoms2
Our patient's symptoms improved with supportive care, he had no further thunderclap headaches, and repeat CT angiography five weeks later demonstrated resolution of [arterial constriction] consistent with RCVS," wrote the physicians. (iflscience.com)
Management of the RCVS usually consists of resting, treating symptoms (e.g. analgesics), and controlling the blood pressure. (researchsquare.com)
Cerebrovascular1
The vasoactive substance may have altered control of cerebrovascular tone, spurring cerebral vasoconstriction that potentially led to RCVS in this case. (medscape.com)
Thunderclap headaches1
Up to 82% to 100% of patients with RCVS have repeated attacks of thunderclap headaches during the clinical course [ 2 , 5 , 6 ]. (pfmjournal.org)
Clinical4
PATIENTS AND METHODS: In a pooled French cohort of 345 patients with RCVS, we assessed (1) rates of clinical and radiological complications, and (2) the functional outcome at 3 months according to age as a continuous variable, and in young patients aged ≤ 49 years versus those aged ≥ 50 years. (bvsalud.org)
If confirmed in larger prospective studies, recognition of age-specific patterns might help to guide clinical management and to identify complications in cases of RCVS and vice versa. (bvsalud.org)
In our study, we describe the clinical features, risk factors, and outcomes of RCVS in a multicenter case series of patients with COVID-19. (henryford.com)
We collected clinical characteristics, imaging, and outcomes of patients with RCVS and COVID-19 identified at each participating site. (henryford.com)
Segmental2
Therefore, brain CT angiography was performed, which revealed the typical "strings and beads" appearance due to segmental vasoconstriction of bilateral posterior cerebral arteries (Fig. 2 A, white arrow-heads). (researchsquare.com)
Because other diseases (such as atherosclerosis) have similar angiographic presentations, it can only be conclusively diagnosed if vasoconstriction resolves within 12 weeks. (wikipedia.org)
Although RCVS generally resolves without significant sequelae, a rare and possibly underrecognized hemorrhagic presentation has a worse potential course. (vcu.edu)
Recurrent1
However, the risk was high amongst those with CAA compared to those caused by RCVS, with recurrent cSAH in 39.1% and subsequent lobar ICH in 43.5% of CAA cases. (elsevierpure.com)
Patients5
Among older patients, sSAH was mainly related to CAA while in younger patients, RCVS represented the most frequent etiology. (bordeaux-neurocampus.fr)
CONCLUSIONS: Our series suggests that patients with COVID-19 may be at risk for RCVS, particularly in the setting of additional risk factors such as exposure to vasoactive agents. (henryford.com)
Although the first such report in the literature, Gunasekaran noted that "with new advances in neuroimaging like cerebral angiography and increased use of vasoactive substances, physicians may encounter a growing number of patients with RCVS spectrum. (medscape.com)
The typical RCVS has thunderclap headache but patients with RCVS without this type of headache have been reported. (pfmjournal.org)
Further research should be performed to test the diagnostic accuracy of HR-MRI in patients with RCVS. (pfmjournal.org)
Severe1
As a result, a headache with thunderclap onset (reaching the peak intensity in less than a minute), of severe intensity, and lasting for 5 minutes or more is considered typical for RCVS [ 7 ]. (pfmjournal.org)
Cases4
Up to two-thirds of RCVS cases are associated with an underlying condition or exposure, particularly vasoactive or recreational drug use, complications of pregnancy (eclampsia and pre-eclampsia), and the adjustment period following childbirth called puerperium. (wikipedia.org)
After studying the medical literature, the team concluded that no other cases of chili pepper-induced RCVS have been recorded. (iflscience.com)
We report three cases of hemorrhagic RCVS and review the literature. (vcu.edu)
The present case suggests that HR-MRI features like dynamic negative remodeling but no enhancement may be a suspicious sign for RCVS, especially in cases with atypical presentation. (pfmjournal.org)
Findings1
Based on these findings, she was diagnosed with RCVS. (researchsquare.com)
RCVS more commonly involves reactions to prescription medications or arises secondary to illicit drug use. (medscape.com)
Females of childbearing age are most commonly affected with RCVS. (bmj.com)
Awareness1
With a recent increase in awareness, RCVS has become the most important cause of thunderclap headache [ 3 , 4 ]. (pfmjournal.org)
Younger1
Younger age and thunderclap headache predict RCVS. (elsevierpure.com)
Migraine1
According to the report's authors, RCVS develops as an adverse response to certain prescription drugs, such as antidepressants and migraine medication, or illicit substances such as cocaine, amphetamines, and ecstasy. (iflscience.com)
Case3
Herein, we describe a successfully treated case of tacrolimus-induced RCVS after heart transplant. (researchsquare.com)
The primary approach to treating RCVS is removal of the offending substance and supportive care, which worked in this case. (medscape.com)
Herein we introduce an unusual case of RCVS without thunderclap headache, together with typical high-resolution magnetic resonance imaging (HR-MRI) features of RCVS showing the possible mechanisms of this condition. (pfmjournal.org)
Conditions1
Many diverse conditions are grouped within the category of RCVS. (vcu.edu)
Patient1
Herein we introduce a patient without thunderclap headache who was diagnosed with RCVS based on high-resolution magnetic resonance imaging (HR-MRI) features. (pfmjournal.org)
Weeks1
Follow-up CT angiography 5 weeks after initial hospitalization revealed resolution of the vasoconstriction. (medscape.com)

Report1
This is the first report of RCVS triggered by human placenta extract. (neurology-jp.org)
Presentation1
However, atypical presentation of RCVS has been reported. (pfmjournal.org)
Risk factors1
