COVID-19 Infection and Recurrent Stroke in Young Patients With Protein S Deficiency: A Case Report
Conclusions: SARS-CoV-2 infection potentializes the prothrombotic effect and vascular inflammation by accentuating protein S deficit. The place of steroids seems justifiable in the presence of symptoms of vasculitis in brain imaging.

High-resolution Intracranial Vessel Wall Imaging in Monitoring Treatment Response in Primary CNS Angiitis
Conclusions: Our report illustrates the utility of HR-VWI in diagnosing a case of PCNS angiitis through the demonstration of a vasculitic pattern of mural enhancement. Furthermore, it has provided evidence of disease response to treatment, assisting us in modifying treatment accordingly. Tracking disease activity and response to treatment in cases of central nervous system vasculitis can be another important use of HR-VWI in clinical practice besides assisting in establishing the diagnosis.

A severe, relapsing case of myelin oligodendrocyte glycoprotein IgG-associated CNS inflammation
A 55-year-old man presented in October 2004 with general unease, vomiting, and gait disturbance. Initially diagnosed with an inner ear infection, the patient's symptoms did not improve and he was evaluated further. MRI revealed a cerebellar lesion, which led to the suspicion of a posterior circulation stroke, and he was started on antiplatelet drugs. However, an angiogram suggested no vascular pathology. In March 2011, he had another episode of ataxia and MRI showed a right brainstem lesion. Cryptogenic stroke was reconsidered. In March 2013, the patient developed paraparesis with urinary and bowel symptoms. MRI revealed m...

Intra-arterial milrinone may differentiate fulminant RCVS from vasculitis
A 39-year-old woman taking a monoamine oxidase inhibitor presented with a 1-week history of severe non-thunderclap headache and visual field deficits. Brain CT showed infarcts in both parietal lobes, with narrowing of intracranial vessels on CT angiogram (figure 1), suggesting either vasculitis or reversible cerebral vasoconstriction syndrome (RCVS). Despite treatment with both methylprednisolone and nimodipine, she experienced progressive aphasia and right leg weakness. She underwent an urgent cerebral angiogram (figure 2), during which intra-arterial milrinone reversed both the vasoconstriction and its symptoms, thereby ...

Teaching NeuroImages: Takayasu arteritis: Neuroimaging progression after immunosuppressant treatment
A 29-year-old woman presented with a 2-year history of heel pain, constitutional symptoms, and increased acute phase reactants. CT and magnetic resonance (MR) angiography revealed a thickening of aortic walls and a thread-like appearance of bilateral subclavian and common carotid arteries. The findings were consistent with Takayasu arteritis (TA)1 and the patient was prescribed methylprednisolone, followed by azathioprine. Follow-up MR angiography, 6 years later, showed an important improvement with only a mild luminal narrowing of both common carotid arteries (figures 1 and 2, A and B). TA is a large-artery inflammatory d...

Spinal Cord Infarction as the Initial Presentation of Systemic Lupus Erythematosus (P2.077)

Digital Subtraction Angiography (DSA) Arch Run in Place of CT Vessel and Perfusion Imaging: Proof of Concept (P1.014)
CONCLUSIONS: In both cases, DSA arch runs generated adequate, rapid vessel imaging including demonstration of collaterals in place of CTA/CTP. This minimized delays in treatment, provided information key to predicting benefit and facilitated a shorter time to reperfusion. This is proof of concept, that DSA arch runs can be used in place of CTA/CTP in patients likely to require intra-arterial therapy.Disclosure: Dr. Campbell has nothing to disclose.
