Border zone cerebral infarcts associated with COVID-19 in CADASIL : a report of 3 cases and literature review
Agnès Aghetti, Talia Amsellem, Dominique Hervé, Hugues Chabriat, Stéphanie Guey
Introduction: Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts And Leukoencephalopathy (CADASIL) is the most common inherited cerebral small vessel disease and is a cause of early onset ischemic lacunar stroke. Coronavirus disease-19 (COVID-19) infection may lead, in addition to acute respiratory syndrome, to vascular complications including stroke. Herein, we report three CADASIL patients presenting with cerebral border-zone infarcts concomitant to COVID-19 infection, and summarize similar cases previously published in literature.
Methods: Clinical and radiological features of the 3 patients were collected and described. A narrative review of literature was performed in PubMed and Google Scholar by the end of 2022 using the "CADASIL" AND "COVID-19" AND "stroke" terms.
Results: In our 3 patients, aged 40 to 58 years, stroke symptoms occurred one to 11 days after the first COVID-19 manifestations. Pulmonary symptoms were mild or absent. One patient presented with hemodynamic failure presumably related to acute cardiomyopathy. Brain magnetic resonance imaging revealed in all cases, ischemic lesions within border-zone areas in both cerebral hemispheres, lesions in the genu of the corpus callosum or in the medium cerebellar peduncles in two cases. The watershed pattern of ischemic lesions was detected in two cases despite any blood pressure drop or severe respiratory dysfunction. Seven CADASIL patients presenting with acute brain infarcts (multiple in 4/7) in context of SARS-CoV-2 infection were identified in literature, despite no fall in blood pressure except for one of them.
Conclusion: Our observations, in line with previous reports, further suggest that COVID-19 infection may alter blood flow autoregulation in the deepest cerebral white matter in CADASIL patients. The thrombocytopathy and endotheliopathy developing during COVID-19 infection may participate to the underlying vascular processes.
