Reversible cerebral vasoconstriction syndrome: an important cause of acute severe headache. Transient ischaemic attacks may be seen and most frequently present with transient visual loss.6 Non‐cephalgic cases are thought to exist, characterized by otherwise unexplained cerebral infarction following a recognized trigger for RCVS and the characteristic arterial changes on imaging. The full text of this article hosted at iucr.org is unavailable due to technical difficulties. This dilatation gives the typical beaded or sausage-shaped appearance of cerebral arteries. 68 (8): 1005-12. Catheter cerebral angiography. in 1993 and named “benign angiopathy of the central nervous system”. posterior reversible encephalopathy syndrome (PRES), primary angiitis of the central nervous system (PACNS), Vasoconstriction following subarachnoid hemorrhage, thunderclap headache associated vasospasm. endstream endstream endobj Here we report a paediatric case of RCVS to highlight this as a potential differential diagnosis for both acute childhood headache and stroke. M, male; CT, computed tomography; MRI, magnetic resonance imaging; FLAIR, fluid‐attenuated inversion recovery; MCA, middle cerebral artery; PCA, posterior cerebral artery; MRA, magnetic resonance angiography; SAH, subarachnoid haemorrhage; VA, vertebral artery; ICA, internal carotid artery. A 13‐year‐old male developed a sudden severe headache, without other neurological deficits, after swimming in cold seawater. endobj endobj 09;2012: 303152. The term ‘reversible cerebral segmental vasoconstriction’ was first used in 1988 by Call et al.,1 who collated data on a series of patients with headache and similar radiological features. Precipitants (including immersion in cold water) are reported in 20% to 30% of cases.7 Other associations include vascular lesions (dissection/aneurysms), catecholamine‐secreting tumours, trauma, and neurosurgical procedures. 6 0 obj Ann. Ducros A, Boukobza M, Porcher R et-al. (b) The left internal carotid artery injection showing minimal irregularity of the A1 and M1 segments of the left middle cerebral artery and anterior cerebral artery (between arrows) and more striking standing wave of the internal carotid artery (between arrowheads). The clinical picture of CNS vasculitis is more often dominated by cognitive deficits, seizures, or focal neurology. %���� Stroke, reported in up to 9% of adult cases, is the most significant determinant of morbidity,6, 13 with neurological sequelae persisting after the vasculature has normalized. Narrative review: reversible cerebral vasoconstriction syndromes. He was on no medication and denied alcohol, tobacco, or substance misuse. These terms include 1,2,4,17: Importantly RCVS should not be confused with posterior reversible encephalopathy syndrome (PRES). Working off-campus? Smooth, tapered narrowings involving large to medium-sized arteries followed by abnormally dilated segments of second-order and third-order branches is the most characteristic finding 13. Focal neurological deficits can occur, secondary to ischemia or convexity subarachnoid hemorrhage. Unable to process the form.

Hypertension is commonly observed and is thought to reflect the disturbance of sympathetic tone.4, Migraine is a distinct entity but may be associated. endstream of RCVS is currently confirmed only in retrospect, when arterial narrowing resolves. 36 (8): 1392. Most cases resolve spontaneously, but arterial ischaemic stroke and intracerebral and subarachnoid haemorrhages complicate a minority. Although there is overlap both in the presumed underlying mechanisms and predisposing factors they are considered separate syndromes. The findings on imaging consist of either direct visualization of the vascular narrowings and/or complication(s) related to vascular narrowings such as: Transcranial Doppler may show increased arterial velocities suggesting vasospasm and decreased luminal caliber of ICA, MCA and ACA 8. ■ Recognize the imaging appearances of various forms of CNS vasculitis. It was first described by Calabrese et al. 12. A retrospective analysis of 139 predominately adult patients reported a history of migraine in up to 40% of the participants.2 Additionally, migraine has been linked with an increased risk of haemorrhage in patients with RCVS.12.

Brain abnormalities on MRI are more commonly seen in vasculitis and notably, are usually evident on scans at presentation compared with early scans in RCVS, which are often normal.6 A recent paper15 has suggested that demonstration of vessel wall enhancement on high‐resolution MRI may enable differentiation between CNS vasculitis and RCVS, but this requires corroboration before diagnostic use.
