2024年10月18日 · CT. CT is useful to rule out aneurysmal subarachnoid hemorrhage. As previously noted, a CT scan can be entirely normal with RCVS. The following can be seen: convexity subarachnoid hemorrhage. ischemic stroke, including watershed infarct. lobar intracerebral hemorrhage. vascular narrowings on CTA. MRI

2019年7月5日 · Reversible cerebral vasoconstriction syndrome (RCVS) is used to describe a multitude of pathologies encompassing the clinical terms Call-Fleming syndrome, thunderclap headache (TCH) with reversible vasospasm, benign angiopathy of the central nervous system, postpartum angiopathy, migrainous vasospasm or migraine angiitis, drug-induced cerebral ...

2023年8月28日 · People with RCVS may need to have both a CT and an MRI. A CT scan is faster and can help diagnose or rule out a stroke because it can spot blood vessel blockages inside your brain. That’s crucial because strokes are time-critical, and every minute counts. An MRI or MRA is often necessary once a healthcare provider rules out a stroke.

2022年6月24日 · The ability to diagnose vasospasm noninvasively, by using either CT or MR angiography, has dramatically advanced the field. With a clearer concept of RCVS and improved diagnostic tools, it's likely that RCVS will be diagnosed more often in the future.

2024年6月14日 · Imaging is crucial for diagnosing and differentiating RCVS from PACNS. When compared, patients with RCVS showed abnormalities in initial computed tomography (CT) or MRI scans 70% of the time, whereas patients with PACNS had exclusively abnormal initial CT or MRI.

2024年10月18日 · RCVS affects women more commonly than men (F:M = 2.4:1) and usually presents between 20-50 years of age (mean 42 years), ... CT. CT is useful to rule out aneurysmal subarachnoid haemorrhage. As previously noted, a CT scan can be entirely normal with RCVS. The following can be seen:

Noncontrast head CT should be the initial examination performed for patients presenting with symptoms suggestive of RCVS, particularly thunderclap headache. Noncontrast CT is an effective way to screen patients for the presence of intracranial hemorrhage, including subarachnoid and intraparenchymal hemorrhage, as well as ischemic stroke.

Reversible cerebral vasoconstriction syndrome (RCVS) is an increasingly recognized and important cause of acute headache. The majority of these patients develop potentially serious neurological complications. Rigorous investigation is required to exclude other significant differential diagnoses.

Reversible Cerebral Vasoconstriction Syndrome (RCVS) is a neurovascular condition characterized by a severe sudden-onset headache that may be associated with focal neurological deficits. On imaging, the suggestive finding corresponds to multifocal vasoconstriction of the cerebral arteries, with a spontaneous resolution of approximately 12 weeks.

2024年5月3日 · Specific markers may facilitate the differentiation of RCVS from other conditions, thereby enhancing patient care. This review explores a wide range of radiological presentations, from vasoconstriction to infarctions and hemorrhages, thereby refining diagnostic criteria and guiding clinical practice.
