Reversible cerebral vasoconstriction syndrome (RCVS) combined with posterior reversible encephalopathy syndrome (PRES) is a rare complication in patients treated with immunosuppressants. A 52-year-old male patient presented with seizures after heart transplantation. The patient was suspected of having PRES on brain images. Despite the strict blood pressure control, the patient presented with altered mentality and the brain images showed a newly developed large acute infarction. Digital subtraction angiography (DSA) revealed the classic "sausage on a string" appearance of the cerebral arteries - potential feature of RCVS...

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...

We report a right-handed 19-year-old girl who developed reversible cerebral vasoconstriction syndrome (RCVS) lateralized to the right hemisphere with simultaneous new-onset left hemispheric seizures. RCVS, typically more diffuse, was lateralized to one of the cerebral hemispheres.

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...

The Czech v351 strain of rabbit haemorrhagic disease virus (RHDV1) is used in Australia and New Zealand as a biological control agent for rabbits, which are an important and damaging introduced vertebrate pest in these countries. However, non-pathogenic rabbit caliciviruses (RCVs) can provide partial immunological cross-protection against lethal RHDV infection and thus interfere with effective rabbit biocontrol. Antibodies that cross-reacted against RHDV antigens were found in wild rabbits before the release of RHDV1 in New Zealand in 1997, suggesting that non-pathogenic RCVs were already present in New Zealand...

Reversible cerebral vasoconstriction syndrome (RCVS) is a cerebrovascular syndrome characterized by multi-segmental constrictions of the cerebral arteries that resolves spontaneously within 3 months. Although RCVS is considered to be due to transient dysregulation of vascular tone, the exact pathomechanism remains unclear. We describe the case of a 15-year-old girl with RCVS induced by tacrolimus, who developed generalized seizure during the postoperative course of orthotropic heart transplantation. Magnetic resonance imaging at symptom onset showed a few vasoconstrictions accompanying brain edema and convexity subarachnoid hemorrhage...

BACKGROUND AND AIM OF THE STUDY: Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by severe "thunderclap" headache, with or without associated neurological symptoms and neuroimaging findings of reversible vasoconstriction of cerebral arteries. Puerperium is a recognized precipitant, but the incidence of puerperal RCVS is unknown. We conducted a prospective study to assess incidence, risk factors and clinical features of RCVS. MATERIAL AND METHOD: Nine-hundred consecutive puerperae were prospectively enrolled within three days of delivery...

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: The aim of this study is to investigate cerebral endothelial dysfunction in patients with reversible cerebral vasoconstriction syndrome (RCVS). METHODS: We prospectively recruited patients with RCVS, age-matched controls with episodic migraine, and age-matched healthy controls at Samsung Medical Center from Apr 2015 to Jul 2016. All participants underwent transcranial Doppler evaluation, with a breath-holding maneuver, for the evaluation of bilateral middle cerebral arteries (MCAs), posterior cerebral arteries (PCAs), and the basilar artery (BA)...

We describe the case of a 10-year-old boy who developed reversible cerebral vasoconstriction syndrome (RCVS) after cerebellitis. He received intravenous immunoglobulin and methylprednisolone to treat the cerebellitis. However, he then presented with a sudden severe headache, vomiting, and generalized tonic-clonic seizure. Brain magnetic resonance angiography (MRA) initially revealed diffuse cerebral vasodilatations, and diffuse multifocal segmental vasoconstrictions developed several days later. His clinical symptoms gradually resolved after several days, in the absence of any specific therapy...

BACKGROUND: Reversible cerebral vasoconstriction syndrome (RCVS) is a rare cause of intracerebral hemorrhage (ICH) causing intracranial hypertension. METHODS: Case report. RESULTS: We report a case of RCVS-related ICH leading to refractory intracranial hypertension. A decompressive craniectomy was performed to control intracranial pressure. We discuss here the management of RCVS with intracranial hypertension. Decompressive craniectomy was preformed to avoid the risky option of high cerebral perfusion pressure management with the risk of bleeding, hemorrhagic complications, and high doses of norepinephrine...

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...

A campaign to encourage senior health professionals to talk about their own experiences of mental health issues was launched by the RCVS Mind Matters Initiative and the Doctors' Support Network last week. The '&me' campaign aims to help tackle the stigma around mental ill health in the health professions. Georgina Mills reports.

Primary central nervous system vasculitis (PCNSV) is a challenging diagnosis due to broad clinical manifestations and variable specificity and sensitivity of laboratory and imaging diagnostic tools. Differential diagnosis includes reversible cerebral vasoconstriction syndrome (RCVS), secondary vasculitis of the CNS and other noninflammatory vasculopathies. Brain biopsy is essential for definitive diagnosis and to exclude mimickers. Recent data show that data large-vessel PCNSV present worse prognosis when compared to small-vessel PCNSV...

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...

BACKGROUND: Middle- and long-term biological variation data for hematological parameters have been reported in the literature. Within-day 24-h variability profiles for hematological parameters are currently lacking. However, comprehensive hour-to-hour variability data are critical to detect diurnal cyclical rhythms, and to take into account the 'time of sample collection' as a possible determinant of natural fluctuation. In this study, we assessed 24-h variation profiles for 20 hematological parameters...
