BACKGROUND: In the emergency setting, non-traumatic headache is a benign symptom in 80% of cases, but serious underlying conditions need to be ruled out. Copeptin improves risk stratification in several acute diseases. Herein, we investigated the value of copeptin to discriminate between serious secondary headache and benign headache forms in the emergency setting. METHODS: Patients presenting with acute non-traumatic headache were prospectively enrolled into an observational cohort study...

OBJECTIVE: Diagnosis of reversible cerebral vasoconstriction syndrome (RCVS) is currently based on luminographic findings of vasoconstriction. In addition to vasoconstriction, the blood-brain barrier (BBB) breakdown has been postulated as a central mechanism of RCVS. Our aim was to document BBB breakdown in patients with RCVS and its role for the pathophysiology-based diagnosis of RCVS. METHODS: We prospectively recruited 72 consecutive patients with thunderclap headache who did not have aneurysmal subarachnoid hemorrhage from April 2015 to July 2016 at the Samsung Medical Center...

BACKGROUND: Reversible cerebral vasoconstriction syndrome (RCVS) is a clinico-radiologic syndrome characterized by thunderclap headache and reversible multifocal arterial constrictions that resolves within 3 months. RCVS can be either spontaneous or related to a trigger; vasoactive drugs including over-the-counter medicine are common culprits. Nevertheless, there are sparse data on the association of herbal supplements in the genesis of unexplained RCVS. METHODS: We describe a case of RCVS with a temporal association with the consumption of a diet pill composed of green tea, L-carnitine, and conjugated linoleic acid...

Reversible cerebral vasoconstriction syndrome (RCVS) is a rare cerebrovascular disorder affecting large- and medium-sized arteries, occurring most commonly in young women. Thunderclap headache is the usual primary symptom; seizure is uncommon. During the postpartum period, seizure is a significant concern. The main causes of postpartum seizures are posterior reversible encephalopathy syndrome and cortical venous thrombosis; RCVS-related postpartum seizure is rare. Despite its rarity, its course may be fulminant, resulting in permanent disability or death if the diagnosis is delayed and treatment is not started promptly...

Reversible cerebral vasoconstriction syndrome (RCVS) is a relatively rare, non-progressive angiopathy frequently heralded by severe thunderclap headache. It is characterised by vasoconstriction of cerebral arteries which usually resolves within three months of onset. Transient focal neurological signs may occur, and persistent deficits associated with haemorrhagic comorbidities have been reported in a small percentage of individuals. In this paper we report the case of RH, a 36-year-old woman who presented at a university teaching hospital in Sydney with a clinical history and radiological evidence consistent with RCVS...

Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by segmental vasospasm and it is often accompanied by either posterior reversible encephalopathy syndrome or stroke. However, other MRI abnormalities have rarely been reported. A 28-year-old woman presented with a thunderclap headache immediately after delivery; MRI showed segmental vasoconstriction and an abnormal signal in the splenium of the corpus callosum. Neuroimaging abnormalities normalized 20 days after the first examination. Only two cases of RCVS with transient splenial lesions (TSL) have so far been reported...

A 19-year-old woman had a thunderclap headache, followed by left hemiparesis and left homonymous hemianopsia. Laboratory tests showed no signs of infection and immunological test results were unremarkable. MRI revealed a cerebral infarction in the right posterior cerebral artery territory, and digital subtraction angiography(DSA)showed right posterior cerebral artery stenosis on day 2. The first follow-up DSA demonstrated an irregular, bead-like appearance on day 9, but the stenotic lesion returned to normal on day 21...

BACKGROUND: Reversible cerebral vasoconstriction syndrome (RCVS), also known as Call-Fleming syndrome, is characterized by thunderclap headaches, non-aneurysmal segmental cerebral vasoconstriction seen on arteriogram, and spontaneously resolves within twelve weeks. Fingolimod has been reported to cause posterior reversible encephalopathy syndrome (PRES) and one case of RCVS. OBJECTIVE: We report a case of RCVS possibly related to fingolimod use, and compare to cases of adverse outcomes in fingolimod use...

OBJECTIVE: Reversible cerebral vasoconstriction syndrome (RCVS) is an underestimated cause of thunderclap headache that shares many characteristics with subarachnoid hemorrhage (SAH). This fact makes the two easily confused by emergency physicians. This study evaluated the clinical manifestations, radiological features, and outcomes of patients with RCVS. METHODS: The electronic medical records of 18 patients meeting the diagnostic criteria of RCVS at our emergency department between January 2013 and December 2014 were retrospectively reviewed...

Aneurysmal subarachnoid hemorrhage (SAH) is a neurological emergency with high risk of neurological decline and death. Although the presentation of a thunderclap headache or the worst headache of a patient's life easily triggers the evaluation for SAH, subtle presentations are still missed. The gold standard for diagnostic evaluation of SAH remains noncontrast head computed tomography (CT) followed by lumbar puncture if the CT is negative for SAH. Management of patients with SAH follows standard resuscitation of critically ill patients with the emphasis on reducing risks of rebleeding and avoiding secondary brain injuries...

REVIEW

There are a number of dangerous secondary causes of headaches that are life, limb, brain, or vision threatening that emergency physicians must consider in patients presenting with acute headache. Careful history and physical examination targeted at these important secondary causes of headache will help to avoid misdiagnosis in these patients. Patients with acute thunderclap headache have a differential diagnosis beyond subarachnoid hemorrhage. Considering the "context" of headache "PLUS" some other symptom or sign is one strategy to help focus the differential diagnosis...

Reversible cerebral vasoconstriction syndrome (RCVS) is a disease characterized by thunderclap headache with severe vasospasm of middle sized vessels of circle of Willis or the extracranial circulation which spontaneously revert back. We report a middle aged female with severe headache and vasospasm of the vertebral arteries and vessels of circle of Willis causing multiple cerebral infarcts. The vasospasm resolved within 3 months.

INTRODUCTION: Reversible cerebral vasoconstriction syndrome (RCVS) typically affects young patients and left untreated can result in hemorrhage or ischemic stroke. Though the disorder has been well characterized in the literature, the most appropriate way to diagnose, treat, and evaluate therapeutic response remains unclear. In previous studies, transcranial Doppler ultrasound (TCD) has shown elevated velocities indicative of vasospasm. This imaging modality is noninvasive and inexpensive; an attractive option for diagnosis and therapeutic monitoring if it is sensitive enough to detect changes in the acute setting given that RCVS often affects the distal vessels early in the course of disease...

Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by thunderclap headaches with diffuse segmental constriction of cerebral arteries that resolves spontaneously within 3 months. We report on a case of a 13-year-old boy presenting with acute severe headaches, triggered by physical exertion. His past medical history was uneventful. Moderate headache persisted between exacerbations for 4 weeks. He secondarily presented with signs of intracranial hypertension. Brain magnetic resonance angiography (MRA) revealed multifocal narrowing of the cerebral arteries...

BACKGROUND AND PURPOSE: Reversible cerebral vasoconstriction syndrome (RCVS) is a vascular headache disorder characterized by severe headaches with vasospasm of cerebral arteries. Transcranial Doppler ultrasonography (TCD) has been widely applied and validated in studying vasospasm of intracranial vessels, but the role of TCD in the diagnosis and monitoring of RCVS is less well established. We sought to determine the reliability of TCD for diagnosis and monitoring of RCVS. METHODS: Patients admitted to an inpatient neurology service between 2011 and 2014 with a discharge diagnosis of RCVS were retrospectively analyzed for demographics, neuroimaging, and functional outcomes...

The term "thunderclap headache" (TCH) was first coined in 1986 by Day and Raskin to describe headache that was the presenting feature of an underlying unruptured cerebral aneurysm. The term is now well established to describe the abrupt onset headache seen with many other conditions and is also now included in The International Classification of Headache Disorders 3(rd) edition beta version rubric 4.4. An essential to label an acute headache as "TCH" and differentiate it from other "sudden onset, severe headaches" is the arbitrary time frame of 1 min from onset to peak intensity for "TCH...
