Call-Fleming syndrome

Vasoconstriction

and hyperperfusion syndrome after carotid artery stenting. A Diffusion-weighted imaging performed upon admission revealed multiple cortical cerebral infarctions. B, C Carotid artery stenting was performed for internal carotid artery stenosis (red arrows). D Preoperatively, atherosclerotic stenosis was observed in the left anterior cerebral artery. Digital subtraction angiography (DSA) was performed at the end of the surgery, and the results showed that the left middle cerebral artery (MCA) was dilated. E DSA performed 1 day after the surgery revealed a localized vasoconstriction mainly of the left MCA. F One week after the surgery, CT perfusion revealed hyperperfusion, with a cerebral blood flow contralateral ratio of greater than 1.3. CT perfusion was scanned using a multidetector CT scanner with 80 detector rows (Aquilion Prime, Canon, Japan) and DSA was performed with biplane equipment (Infinix Celeve-i INFX-8000 V, Canon, Japan). MRI scanner was 1.5 T scanner (Magnetom Avanto fit, Siemens Healthcare, Germany)

cerebral vasoconstriction syndrome: case report. Brain magnetic resonance imaging FLAIR (a) and diffusion-weighted (b) sequences showed acute ischemia within the right centrum semiovale. MR angiography demonstrated multiple stenotic segments both in anterior and posterior circulations particularly in the right arteria cerebri media (c)

cerebral vasoconstriction syndrome: case report. Digital subtraction angiography revealed multifocal segmental vasoconstriction in anterior circulation (a) which largely resolved 7 weeks later (b). Multiple segments of narrowing in vessel calibre in basilar artery (c) were also improved after therapy (d)

Reversible

cerebral vasoconstriction syndrome associated with autonomic dysreflexia. MRI, T2-weighted image (a) and CT (b) of the brain after 6 months demonstrating a large infarction in the left hemisphere

cerebral vasoconstriction syndrome with cerebral infarction caused by acute high-level vapor exposure of ethylene oxide: a case report. Initial and follow-up axial T1WI, FLAIR, DWI, and ADC brain MRI. A-D: Axial T1WI, FLAIR, DWI, and ADC brain MRI performed 5 days after inhalation indicated that there was no noticeable abnormality. E-H: Axial T1WI, FLAIR, DWI, and ADC brain MRI performed 12 days after exposure demonstrates extensive cytotoxic edema in the parietal and occipital lobes bilaterally, left frontal lobe, centrum semiovale region. I-L: Axial T1WI, FLAIR, DWI, and ADC brain MRI performed 59 days after exposure demonstrates a notable improvement of the intracranial arterial stenosis

Reversible

cerebral vasoconstriction syndrome associated with autonomic dysreflexia. Selective catheter cerebral angiography (a) 9 days after admission, demonstrating multiple calibre changes in the intracranial blood vessels (left hemisphere). MRI, diffusion-weighted imaging (DWI) (b) 2 weeks after admission demonstrating acute ischaemic changes in the left hemisphere. Follow-up MRI, DWI (c) and T2-weighted image (d) 3 weeks after admission demonstrating reduction of ischaemic changes

Reversible

cerebral vasoconstriction syndrome presenting as an isolated primary intraventricular hemorrhage. Catheter angiography of left vertebral artery demonstrated vasoconstriction. The arrows point to multifocal areas of irregular narrowing of the distal branches of the left posterior cerebral artery

Reversible

cerebral vasoconstriction syndrome presenting as an isolated primary intraventricular hemorrhage. MRI brain [fast low angle shot (FLASH) sequence] demonstrated intraventricular hemorrhage; no causative underlying vascular lesion was identified

cerebral vasoconstriction syndrome in a patient taking citalopram and Hydroxycut: a case report. RCVS on computed tomography angiography. CTA obtained during hospitalization showed multifocal segmental vasoconstrictions most prominent in the bilateral anterior (A) and posterior (B) cerebral arteries. Follow-up CTA six weeks after discharge revealed marked resolution of cerebral artery vasoconstriction, shown here for anterior (C) and posterior (D) cerebral arteries.

cerebral vasoconstriction syndrome in a patient taking citalopram and Hydroxycut: a case report. RVCS-related ischemic strokes. Diffusion-weighted MRI (A, B, C) and apparent diffusion coefficient maps (D, E, F) revealed lesions in the right occipital lobe and bilateral anterior cerebral artery territories consistent with ischemic strokes.

cerebral vasoconstriction syndrome with cerebral infarction caused by acute high-level vapor exposure of ethylene oxide: a case report. Initial and follow-up CTA and MRA. The 15 days and 21 days after ethylene oxide inhalation, Head MRA (A) and CTA (B) showed multiple areas of stenosis and partial occlusions involving the anterior, medial and posterior cerebral arteries bilaterally, respectively. The 59 days after ethylene oxide inhalation, the follow-up head MRA (C) showed that the cerebral arterial stenosis was markedly improved but not complete recovery
