A 65-year-old man who had been diagnosed with transient global amnesia (TGA) 15 years previously was admitted to hospital with complaints of amnesia and headache. His symptoms improved on day-2. The initial brain MRI and electroencephalography findings were normal. He was diagnosed with a recurrence of TGA and discharged. However, he returned with right leg weakness and complained of a thunderclap headache. MRI demonstrated subarachnoid hemorrhage and multifocal segmental narrowing of the left posterior cerebral artery (PCA) and large intracranial arteries, and he was diagnosed with reversible cerebral vasoconstriction syndrome (RCVS)...

Background Reversible cerebral vasoconstriction syndrome (RCVS) is an important differential diagnosis of singular or recurrent thunderclap headache. Prognosis is generally good, however complications of the transient segmental vasospasms of cerebral arteries such as stroke, subarachnoidal hemorrhage and brain edema may worsen the clinical outcome. Although the exact pathomechanism is still unclear, various vasoactive substances and conditions (e.g. post partum) have been identified as triggering RCVS. Cases We report on the clinical course and management of two cases of typical RCVS that were associated with two different precipitants previously not described: A gastrointestinal infection and isoflavones, which are phytoestrogens used for menopausal vasomotor symptoms...

Objectives To report demographics and characteristics of reversible cerebral vasoconstriction syndrome (RCVS) in the Korean cohort. Methods We prospectively recruited patients with definite (imaging-proven) RCVS and probable (imaging-negative) RCVS who visited Samsung Medical Center between June 2012 and September 2016. Clinical manifestations, neuroimaging, treatment, and clinical outcomes were evaluated in all patients. Characteristics of RCVS without typical causes ("idiopathic RCVS") were compared with those of RCVS with identifiable causes ("secondary RCVS")...

BACKGROUND: Headache is a common patient complaint. The threshold for brain imaging in headache is debated, especially when the headache is transient, although even if the headache has resolved at presentation a sentinel bleed heralding a subarachnoid haemorrhage (SAH) often remains a concern. AIMS: To assess the yield of computed tomography (CT) head scan referrals for patients with transient headache symptoms. METHODS: This study looked at six months of CT results assessing for brain pathology with a particular focus on subarachnoid haemorrhage...

We describe a 39-year-old man who developed thunderclap headaches during a hospital admission for accidental superficial burns. His magnetic resonance brain imaging was normal expect for diffuse segmental vasoconstriction. Prior to admission, he was consuming excessive amounts of caffeine which was restarted and slowly tapered and stopped over weeks. Repeat magnetic resonance angiogram showed resolution of segmental vasoconstriction. The implications of prescribed and non-prescribed drugs on cerebral vasculature have been discussed...

Reversible cerebral vasoconstriction syndrome (RCVS) is a rare but increasingly recognized disorder with over 500 cases published in the literature. The condition is characterized by recurrent severe thunderclap headaches with or without other neurological symptoms and diffuse segmental narrowing of the cerebral arteries which is reversible within 3 months. RCVS may occur spontaneously but in over 50% of cases, it is associated with various other conditions, including vasoactive medications or illicit drugs and the post-partum state...

Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by reversible multifocal narrowing of cerebral arteries heralded by sudden (thunderclap) headaches with or without neurological deficits, resolving within 3 months. It often occurs in the peripartum period. To date, the ideal treatment remains unclear.Here, we report the case of a 31-year-old primigravida who presented with intracranial hemorrhage and went on to develop RCVS and acute respiratory distress syndrome over the course of her illness...

BACKGROUND: Reversible cerebral vasoconstriction syndrome occurs predominantly in middle-aged women. Only nine pediatric cases of this syndrome have been reported. PATIENT DESCRIPTION: We present a ten-year-old boy with reversible cerebral vasoconstriction syndrome with radiographic findings similar to those of posterior reversible encephalopathy syndrome (PRES). He presented with a thunderclap headache without a neurological deficit. Brain magnetic resonance angiography (MRA) revealed multifocal narrowing of the cerebral arteries, whereas magnetic resonance imaging (MRI) with diffusion-weighted imaging and fluid-attenuated inversion recovery demonstrated hyperintense lesions in the occipital lobes and the left cerebellum...

PURPOSE: Headache is a common presenting feature of patients with pituitary adenomas and other tumors of the sellar region. However, at present, it still is unclear whether the headache is actually caused by the tumor. To explore whether there is a relation, we examined in detail the headache types, their relationship to the underlying pathology, and if the headache responded to neurosurgery in a prospective study design. METHODS: One hundred twelve patients with tumors of the sellar region scheduled for neurosurgery in a single center were analyzed for presence and quality of headache before surgery and at least 3 months after surgery...

BACKGROUND: Primary angiitis of the CNS (PACNS) typically manifests with accumulating neurologic deficits from ischemic strokes. Intracerebral hemorrhage (ICH) is an uncommon complication. There is limited knowledge about the risk factors and features of hemorrhagic PACNS. METHODS: We identified 49 patients (20 biopsy-proven) with PACNS diagnosed at our hospital from 1993 to 2015. We compared the features of hemorrhagic and nonhemorrhagic PACNS and analyzed the hemorrhagic PACNS cases in detail...

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...
