Abstract
INTRODUCTION Extrapolating from efficacy in subarachnoid haemorrhage (SAH), nimodipine has been used as a treatment for reversible cerebral vasoconstriction syndrome (RCVS). However, 4-hourly dosing is a practical limitation and verapamil has been proposed as an alternative. The potential efficacy, adverse effects, preferred dosing and formulation of verapamil for RCVS have not been systematically reviewed previously. METHOD A systematic review was conducted of the databases PubMed, EMBASE, and the Cochrane Library from inception to July 2022 for peer-reviewed articles describing the use of verapamil for RCVS. This systematic review adheres to the PRISMA guidelines and was registered on PROSPERO. RESULTS There were 58 articles included in the review, which included 56 patients with RCVS treated with oral verapamil and 15 patients treated with intra-arterial verapamil. The most common oral verapamil dosing regimen was controlled release 120 mg once daily. There were 54/56 patients described to have improvement in headache following oral verapamil and one patient who died from worsening RCVS. Only 2/56 patients noted possible adverse effects with oral verapamil, with none requiring discontinuation. There was one case of hypotension from combined oral and intra-arterial verapamil. Vascular complications including ischaemic and haemorrhagic stroke were recorded in 33/56 patients. RCVS recurrence was described in 9 patients, with 2 cases upon weaning oral verapamil. CONCLUSIONS While no randomised studies exist to support the use of verapamil in RCVS, observational data support a possible clinical benefit. Verapamil appears well tolerated in this setting and represents a reasonable treatment option. Randomised controlled trials including comparison with nimodipine are warranted.

Abstract
Headache is the third cause of visits to pediatric emergency departments (ED). According to a systematic review, headaches in children evaluated in the ED are primarily due to benign conditions that tend to be self-limiting or resolve with appropriate pharmacological treatment. The more frequent causes of non-traumatic headache in the ED include primitive headaches (21.8–66.3%) and benign secondary headaches (35.4–63.2%), whereas potentially life-threatening (LT) secondary headaches are less frequent (2–15.3%). Worrying conditions include brain tumors, central nervous system infections, dysfunction of ventriculo-peritoneal shunts, hydrocephalus, idiopathic intracranial hypertension, and intracranial hemorrhage. In the emergency setting, the main goal is to intercept potentially LT conditions that require immediate medical attention. The initial assessment begins with an in-depth, appropriate history followed by a complete, oriented physical and neurological examination. The literature describes the following red flags requiring further investigation (for example neuroimaging) for recognition of LT conditions: abnormal neurological examination; atypical presentation of headaches: subjective vertigo, intractable vomiting or headaches that wake the child from sleep; recent and progressive severe headache (<6 months); age of the child <6 years; no family history for migraine or primary headache; occipital headache; change of headache; new headache in an immunocompromised child; first or worst headache; symptoms and signs of systemic disease; headaches associated with changes in mental status or focal neurological disorders. In evaluating a child or adolescent who is being treated for headache, physicians should consider using appropriate diagnostic tests. Diagnostic tests are varied, and include routine laboratory analysis, cerebral spinal fluid examination, electroencephalography, and computerized tomography or magnetic resonance neuroimaging. The management of headache in the ED depends on the patient's general conditions and the presumable cause of the headache. There are few randomized, controlled trials on pharmacological treatment of headache in the pediatric population. Only ibuprofen and sumatriptan are significantly more effective than placebo in determining headache relief.

Abstract
Descriptions of the natural history of cerebrovascular complications of sickle cell disease (SCD) characterize ischemic stroke as common during childhood and hemorrhagic stroke as more common in adulthood. Childhood ischemic stroke is attributed to vasculopathy with moyamoya syndrome. Hemorrhagic stroke is commonly attributed to aneurysms accompanying HbSS cerebral vasculopathy in SCD. However, a growing body of literature highlights multiple contributing factors to hemorrhagic stroke in children. Primary hemorrhagic stroke is one of the most devastating neurological complications of SCD. We describe the case of an 18-year-old female affected by HbSS genotype SCD presenting with reversible cerebral vasoconstriction syndrome (RCVS) as well as features of posterior reversible encephalopathy syndrome and convexity subarachnoid hemorrhage (SAH) after transfusion of red blood cells. We reviewed the existing literature dealing with SCD, blood transfusion, and hemorrhagic strokes. To our knowledge, this case presentation is unique with convexity SAH predominantly attributable to a RCVS spectrum disorder occurring in the setting of a recent blood transfusion in an adolescent female with SCD. As this case illustrates, neurological deterioration accompanied by intracranial hemorrhage in children and young adults with SCD after blood transfusion should raise suspicion for RCVS as part of a complex cerebral vasculopathy. A better understanding of the risk factors leading to hemorrhagic stroke may help prevent this severe complication in subjects with SCD. Neuroimaging including angiography in these subjects may enable prompt diagnosis and management.

Abstract
Reversible cerebral vasoconstriction syndrome is a transient vasculopathy associated with severe headaches and stroke. In most cases of reversible cerebral vasoconstriction syndrome, there is a precipitating event or trigger, such as pregnancy, serotonin agonist treatment or illicit drug use. The authors present 2 pediatric cases of reversible cerebral vasoconstriction syndrome and review the previous 11 pediatric cases in the literature. In many instances, the clinical and radiographic features are similar in both pediatric and adult cases. In the pediatric group, reported potential triggers include trauma (1/13), exercise (2/13), water to the face (3/13), hypertension (3/13), and medication or substance use (4/13). One surprising difference is that 11 out of 13 pediatric patients with reversible cerebral vasoconstriction syndrome are male while most cases in adults are female. Many of the pediatric patients with reversible cerebral vasoconstriction syndrome were treated with a calcium channel blocker and the overall outcome of pediatric reversible cerebral vasoconstriction syndrome was good, with most patients experiencing a full recovery.

Abstract
BACKGROUND Reversible cerebral vasoconstriction syndrome occurs predominantly in middle-aged women. Only nine pediatric patients with 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 patient's symptoms resolved spontaneously after a few hours with no recurrence. MRA on the second day showed a complete normalization of the affected arteries, and MRI after one month demonstrated improvement in the abnormal findings, leading to a diagnosis of RCVS with radiographic findings similar to those of PRES. CONCLUSIONS This child's findings suggests that, RCVS, with or without PRES, may occur in children who present with a thunderclap headache.

Abstract
We report a pediatric case of reversible cerebral vasoconstriction syndrome with focal seizures without a thunderclap headache. A 7-year-old girl had a mild acute headache with nausea after swimming. She subsequently developed hemi-convulsions followed by right hemiplegia. Brain magnetic resonance angiography revealed generalized vasoconstriction of the main cerebral peripheral arteries. Her hemiplegia was spontaneously resolved within 6h. Over the next 24h she suffered from recurrent and transient headaches, which recurred on days 3 and 5. Follow-up magnetic resonance angiography on day 3 documented the multifocal narrowing of the main cerebral arteries, which was observed to have diminished at 12weeks after her initial presentation. She did not have any headaches or neurological deficits after day 5. This case indicates that reversible cerebral vasoconstriction syndrome should be considered in children with focal seizures even when they do not present with thunderclap headaches. The timely and appropriate evaluation by magnetic resonance angiography and imaging is essential for diagnosing reversible cerebral vasoconstriction syndrome.

Abstract
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. A glucocorticoid treatment was started based on the hypothesis of primary angiitis of the CNS. The symptoms rapidly improved, and repeat angiography at 3 months showed no vasoconstriction. Although pediatric cases are rare, RCVS should be considered in a child complaining of severe headache, especially after the use of vasoactive drugs or after Valsalva manoeuvres. RCVS is attributed to a transient, reversible dysregulation of cerebral vascular tone, which leads to multifocal arterial constriction and dilation. Physical examination, laboratory values, and initial cranial computed tomography are unremarkable, except when RCVS is associated with complications. Thunderclap headaches tend to resolve and then recur over a 1- to 4-week period, often with a milder baseline headache persisting between acute exacerbations. Angiography shows segmental narrowing and dilatation of one or more arteries, like a string of beads. Despite the absence of a proven treatment, important steps should be taken during the acute phase: removal of precipitants such as vasoactive substances, giving the patient rest, lowering blood pressure, and controlling seizures. Drugs targeted at vasospasms, such as calcium channel inhibitors, can be considered when cerebral vasoconstriction has been assessed. In most patients, the RCVS symptoms resolve spontaneously within days or weeks. Ischemic and hemorrhagic stroke are the major complications of the syndrome. A diagnosis of RCVS can only be confirmed when the reversibility of the vasoconstriction is assessed.

Abstract
Pediatric neurology relies on ultrasound, computed tomography (CT), and magnetic resonance (MR) imaging. CT prevails in acute neurologic presentations, including traumatic brain injury (TBI), nontraumatic coma, stroke, and status epilepticus, because of easy availability, with images of diagnostic quality, e.g., to exclude hemorrhage, usually completed quickly enough to avoid sedation. Concerns over the risks of ionizing radiation mean re-imaging and higher-dose procedures, e.g., arteriography and venography, require justification. T1/T2-weighted imaging (T1/T2-WI) MR with additional sequences (arteriography, venography, T2*, spectroscopy, diffusion tensor, perfusion, diffusion- (DWI) and susceptibility-weighted imaging (SWI)) often clarifies the diagnosis, which may alter management in acute settings, as well as chronic conditions, e.g., epilepsy. Clinical acumen remains essential to avoid imaging, e.g., in genetic epilepsies or migrainous headaches responding to treatment, or to target sequences to specific diagnosis, e.g., T1/T2-WI for shunt dysfunction (with SWI for TBI); DWI, arteriography including neck vessels, and venography for acute hemiplegia or coma; coronal temporal cuts for partial epilepsy; or muscle imaging for motor delay. The risk of general anesthesia is low; "head-only" scanners may allow rapid MRI without sedation. Timely and accurate reporting, with discrepancy discussion between expert neuroradiologists, is important for management of the child and the family's expectations.

Abstract
Sudden, severe, and life-threatening, the crises associated with baroreflex failure are diagnostically challenging, particularly in children, a population in which it has rarely been described. The baroreflex failure syndrome results from impaired afferent baroreceptive input and manifests with autonomic stimulation-induced surges in blood pressure and heart rate accompanied by distinct signs, including thunderclap headache, diaphoresis, and emotional instability. Although the adult literature includes cases of severe headache in baroreflex failure,(1) (,) (2) we present the first case of a child with recurrent thunderclap headache and cerebral vasospasm with baroreflex failure secondary to vascular complications of a rare genetic connective tissue disorder.

Abstract
BACKGROUND Call-Fleming syndrome, also known as reversible cerebral vasoconstriction syndrome, is an important cause of severe headache characterized by segmental constriction of cerebral arteries in multiple vascular distributions. It is commonly described in adults, with a female predominance. PATIENT We report a case of a 16-year-old girl with history of anxiety, attention deficit hyperactivity disorder, and migraines on several medications presenting with 2 weeks of worsening headaches. RESULTS Cranial computed tomography was normal, but magnetic resonance imaging revealed cortical subarachnoid hemorrhage. Follow-up imaging demonstrated extensive vasoconstriction of small- to medium-sized cerebral arteries. Sertraline and methylphenidate were discontinued, and nifedipine was started. Symptoms rapidly improved, and repeat angiography at 2 months showed no vasoconstriction. CONCLUSIONS Call-Fleming syndrome is an important cause of thunderclap headache and should be considered in the pediatric population, especially in the setting of certain medication usage and other known risk factors.

Abstract
Reversible cerebral vasoconstriction syndrome (RCVS) is a clinicoradiological diagnosis comprising 'thunderclap' headaches and reversible segmental vasoconstriction of cerebral arteries, occasionally complicated by ischaemic or haemorrhagic stroke. We report a case of RCVS in a 13-year-old male with severe thunderclap headaches and no focal neurological signs. Brain imaging showed multiple posterior circulation infarcts; cerebral computed tomography, magnetic resonance imaging, and catheter angiography showed multifocal irregularity and narrowing, but in different arterial segments. Laboratory studies did not support a diagnosis of vasculitis. Symptoms resolved over 3 weeks; magnetic resonance angiography 3 months later was normal and remained so after 2 years. We highlight the typical clinical features of RCVS in this case and suggest that the diagnosis should be considered in children with thunderclap headaches or stroke syndromes where headache is a prominent feature, especially if cerebrovascular imaging studies appear to be evolving or discrepant.

Abstract
The reversible cerebral vasoconstriction syndrome (RCVS) is an under-estimated transient acute cerebrovascular disorder. It has long been mistaken as central nervous system vasculitis whereas it is now believed to result from an acute but prolonged vasospasm of cerebral arteries. This disorder can be precipitated by postpartum or vasoactive drug. However, it occurs spontaneously in a significant number of cases. The characteristic clinico-radiological presentation and disease course of the RCVS has been delineated only recently. Mean age at onset is 40-45 years, with a female predominance. A provocative factor can be identified in 12-60% out of the patients. Clinical presentation is predominantly marked by recurrent thunderclap headaches, but can be complicated with focal neurological deficit or seizures. Brain imaging is normal in most cases, but can reveal hemorrhagic or ischemic complications. Cortical subarachnoid hemorrhage is a suggestive finding. A posterior reversible encephalopathy syndrome (PRES) can be seen occasionally. Cerebral angiography reveals multifocal arterial narrowing with string and bead appearance. Cerebrospinal fluid reveals no or mild abnormalities. The disease resumes spontaneously within several days to weeks, whereas vasoconstriction reverses within 1 to 3 months. This clinico-radiological presentation should be promptly recognized in order to avoid unnecessary investigations and aggressive treatment, and lead to search for a triggering factor. Further studies are required in order to clarify the precipitating role of several drugs, and clinical trials are needed to reduce the occurrence of strokes.
