BACKGROUND: Reversible cerebral vasoconstriction syndrome (RCVS) is a rare entity with an unknown pathophysiology. RCVS has been reported to occur more frequently in women aged 20 to 50 years. Several mechanisms have been postulated involving transient deregulation of cerebral arterial tone, small vessel endothelial dysfunction, biochemical factors, hormonal deregulation, oxidative stress, and genetic predisposition. All these mechanisms and triggers are related with sympathetic over-activation which eventually produce vasoconstriction...

BACKGROUND: Dissecting aneurysm on the posterior inferior cerebellar artery (PICA) is a very rare entity, endovascular embolization is often adopted. During procedure, if the parent artery is occluded, the distal PICA is usually supplied by the ipsilateral anterior inferior artery or the contralateral PICA. In extremely rare circumstances, the distal PICA can establish collateral circulation by transdural anastomosis with the posterior meningeal artery (PMA). CASE DESCRIPTION: A 29-year-old woman was admitted complaining of thunderclap headache, nausea, and vomiting for 3 hours...

Reversible cerebral vasoconstriction syndrome (RCVS) is a clinicoradiological syndrome that occurs due to dysfunction of cerebrovascular autoregulation. It is characterized by recurrent thunderclap headache from cerebral vasoconstriction which can cause ischemic infarction, spontaneous intraparenchymal and subarachnoid hemorrhage. This syndrome can be triggered by a variety of etiologies including medications, infectious, and inflammatory conditions. The diagnosis is often delayed due to unawareness among the health-care providers and delayed neuroimaging evidence of vasoconstriction with or without ischemic and/or hemorrhagic infarction...

Background Paroxysmal neurological symptoms occurring with sex cause considerable anxiety and sometimes have a serious cause. Thunderclap headache is the most well-known and requires urgent investigation at first presentation for subarachnoid haemorrhage and other significant pathologies. After exclusion of underlying causes, many prove to be primary headache associated with sexual activity. Orgasmic migraine aura without headache is not currently recognised as a clinical entity. Case reports We report two patients with acephalgic orgasmic neurological symptoms fulfilling the criteria for migraine aura...

Introduction We previously reported centripetal propagation of vasoconstriction at the time of thunderclap headache remission in patients with reversible cerebral vasoconstriction syndrome. Here we examine the clinical significance of centripetal propagation of vasoconstriction. Methods Participants comprised 48 patients who underwent magnetic resonance angiography within 72 h of reversible cerebral vasoconstriction syndrome onset and within 48 h of thunderclap headache remission. Results In 24 of the 48 patients (50%), centripetal propagation of vasoconstriction occurred on magnetic resonance angiography at the time of thunderclap headache remission...

Differential diagnosis of migraine, can be difficult, especially of migraine with aura. On the one hand, some diseases can produce symptoms similar to migraine (cerebral aneurysm before rupture, reversible cerebral vasoconstriction syndrome). On the other hand, migraine with aura and some other disorders are conditions that have common pathophysiological mechanisms (e.g., CADASIL and MELAS syndrome, antiphospholipid syndrome). Thirdly, clinical presentations of migraine are often difficult to distinguish from features of other headache conditions (migraine with aura - transient ischemic attack, migraine with visual aura - occipital epilepsy)...

Life-threatening headaches in children can present in an apoplectic manner that garners immediate medical attention, or in an insidious, more dangerous form that may go unnoticed for a relatively long period of time. The recognition of certain clinical characteristics that accompany the headache should prompt recognition and referral to an institution equipped with neuroimaging facilities, pediatric neurosurgeons, and neurologists. Thunderclap headaches, which reach a peak within a very short period of time, may be the presenting feature of conditions such as arterial dissection, venous sinus thrombosis, and reversible cerebral vasoconstriction syndrome, which can be addressed by specific pharmacological options instituted in an intensive care setting...

A 72-year-old Japanese woman with rheumatoid arthritis whose activity decreased with previous treatments had recurrent thunderclap headaches during an atovaquone regimen for the treatment of pneumocystis pneumonia. The recurrent headaches disappeared after discontinuation of the drug. Brain magnetic resonance images showed multiple cerebral vasoconstrictions of cerebral arteries with vasogenic cerebral white matter edema, which diminished several weeks later. We diagnosed the patient's headaches as reversible cerebral vasoconstriction syndrome due to atovaquone...

Cough headache can be a primary benign condition or secondary to underlying etiologies. We herein describe a case of a 52-year-old woman with cough headache that presented as reversible cerebral vasoconstriction syndrome (RCVS). Some cases of RCVS are caused by an aberrant sympathetic response to activities that cause an intracranial pressure surge. Therefore, cough headache should be recognized as a possible presentation of RCVS, even without thunderclap headache or neurological deficits.

Reversible cerebral vasoconstriction syndrome (RCVS) is increasingly being recognized as a diagnosis in patients presenting with thunderclap headaches. In the vast majority of the cases, the syndrome follows a benign course and patients recover completely without any significant therapeutic intervention. In the rarest of cases, RCVS follows a monophasic course with rapid worsening, severe neurological deficits, and poor outcomes. We present the case of a 25-year-old female who presented with headaches which were worsening over 1 week...

M T Arrigan, M K S Heran, J R Shewchuk
Reversible cerebral vasoconstriction syndrome is an intracranial vascular manifestation of a wide variety of diseases. It is the second most common cause of thunderclap headache, the most common cause of recurrent severe secondary headaches, and, in patients <60 years of age, has been reported as the commonest cause of isolated convexity subarachnoid haemorrhage. Radiologically, its key feature is vasoconstriction of the intracranial vessels, a dynamic process that is typically maximal at 2 weeks, varies in its distribution over the course of the disease, and typically resolves after 3 months...

Reversible cerebral vasoconstriction syndrome (RCVS) is a distinct clinical syndrome characterized by thunderclap headache and reversible cerebral vasoconstriction. An association between RCVS and arterial dissection has emerged in recent years, where dissection typically involves the cervical vertebral arteries. In this vignette, we describe isolated reversible vasoconstriction, involving the extracranial arteries and intracranial dissection-a combination hitherto never reported.

Objectives To serially test the International Classification of Headache Disorders (ICHD) 3rd edition beta version criteria for 6.7.3.1 probable reversible cerebral vasoconstriction syndrome (probable RCVS) in patients with thunderclap headache. Methods We prospectively screened consecutive patients with thunderclap headache who visited the Samsung Medical Center between October 2015 and March 2017. Patients were included in the analysis if they a) visited our hospital within 1 month after onset, b) completed a diagnostic work-up, and c) had no secondary causes other than RCVS...

Case: Reversible cerebral vasoconstriction syndrome (RCVS) is an increasingly recognized and important cause of thunderclap headache. Delays in diagnosis may cause deterioration of symptoms and concomitant unnecessary investigations. However, the diagnosis of RCVS in the acute stage remains difficult.A 41-year-old man was admitted to the emergency department for severe, recurrent occipital headaches. The results of initial computed tomography and magnetic resonance imaging (MRI) of the brain and cerebrospinal fluid analysis were normal...

Pneumocephalus is a rare condition characterized by the presence of gas within the cranial cavity. This gas arises either from a trauma, tumor, surgical procedure, or occasionally from infection. Pneumocephalus secondary to chronic otitis media is an extremely rare phenomenon. We describe here a 70-year-old male, a known case of chronic suppurative otitis media who presented with sudden onset severe thunderclap headache and was eventually diagnosed as pneumocephalus.

INTRODUCTION: Subarachnoid hemorrhage (SAH) is a life-threatening emergency that is frequently missed due to its varied and often subtle presentation. The most common presentation of SAH is with a severe headache. The classical adjective used in SAH is "thunderclap"; however, this has not been well defined in the literature, rendering it a challenge to triage patients in clinical practice presenting with severe headache. METHODS: We undertook a prospective, observational study at a tertiary academic medical center examining the clinical characteristics of the presenting headache in SAH...

AIMS: To prospectively assess the incidence and etiology (ie, primary vs symptomatic) of headache in women during the first month postdelivery, with particular emphasis on the type of presentation as a clue for identifying potentially harmful etiologies. A secondary aim was to evaluate the relative frequency of migraine- vs tension-type headache in cases of primary headache. METHODS: A total of 900 consecutive women were enrolled in the study and examined within 3 days of delivery, both clinically and with transcranial color-coded sonography (TCCS)...

OBJECTIVE: Thunderclap headache and visual disturbances are typical clinical features of pituitary apoplexy (PA). Because of the acute symptomatology, many patients are referred to a neurosurgical department without prior endocrinological assessment. It is the aim of the present study to analyze initial presenting symptoms, outcome and associated endocrine disturbances in a cohort of patients with pituitary apoplexy primarily seen by neurosurgeons. PATIENTS AND METHODS: Retrospective single-center study in a neurosurgical department...
