Imaging Findings of Ischemic Stroke Associated with COVID-19

Abstract

Objective: We aimed to present the relationship between ischemic stroke and COVID-19, stroke types, and imaging findings in COVID-19 with stroke.

Material Method: From March to November 2020, COVID-19 diagnosed in patients with stroke (n=10) was included in the study retrospectively. To eliminate intracranial hemorrhage, a non-contrast computed tomography (CT) was performed for all patients. Then, magnetic resonance imaging (MRI) and Diffusion-Weighted MRI (DWI) (n=10) were obtained. Magnetic resonance angiography was performed in patients whose CT angiography was contraindicated. Clinical information, stroke risk factors, and case imaging results were recorded. Stroke time, size, location (cortical, deep lacunar, and white matter), and vascular territory area were evaluated.

Results: The mean age of the 10 patients included in the study was 62±15.10 years. All patients had an ischemic stroke. In total, 4 cases (40%) did not have any risk factors for cerebral vascular disease. Based on DWI results, seven cases were assessed as acute strokes (70%) and three cases as sub-acute strokes (30%). The size of the stroke was 21.80±15.83mm. In 4 cases, the size was extended cortical areas. 3 cases were cortical, 5 cases had a lacunar infarction, 2 cases had cortical and lacunar infarctions. 6 cases were in the posterior cerebral artery territory and 4 cases were in the anterior territory.

Conclusion: The presentation of patients with stroke during COVID-19 therapy or after therapy might be considered the hypothesis that the virus led to a stroke, especially in cases accompanied by risk factors.

COVID-19 ile İlişkili İskemik İnmenin Görüntüleme Bulguları

Abstract

Amaç: İnme ile COVID-19 arasındaki ilişkiyi, inme tipleri ve görüntüleme bulguları sunmayı amaçladık.

Gereç ve Yöntem: Mart-Kasım 2020 arasında, inmesi olan (n = 10) COVID-19 teşhisi konulan hastalar retrospektif olarak çalışmaya dahil edildi. İntrakraniyal kanamayı ortadan kaldırmak için tüm hastalara kontrastsız bilgisayarlı tomografi (BT) yapıldı. Daha sonra manyetik rezonans görüntüleme (MRI) ve Difüzyon Ağırlıklı MR (DAG) elde edildi. BT anjiyografisi kontrendike olan hastalara manyetik rezonans anjiyografi yapıldı. Klinik bilgiler, inme risk faktörleri ve görüntüleme sonuçları kaydedildi. İnme süresi, boyutu, konumu (kortikal, derin laküner ve beyaz cevher) ve vasküler bölge alanı değerlendirildi.

Bulgular: Çalışmaya alınan 10 hastanın ortalama yaşı 62±15.10 idi. Tüm hastalarda iskemik inme vardı. Toplamda 4 vakada (%40) serebral vasküler hastalık için herhangi bir risk faktörü yoktu. DAG sonuçlarına göre yedi vaka akut inme (%70) ve üç vaka subakut inme (%30) olarak değerlendirildi. İnme boyutu 21.80±15.83 mm idi. 4 olguda geniş kortikal, 3 olgu kortikal, 5 olguda laküner, 2 olguda kortikal ve laküner enfarktüs vardı. 6 olgu arka serebral arter bölgesinde ve 4 olgu ön serebral bölgede idi.

Sonuç: COVID-19 tedavisi sırasında veya tedaviden hemen sonra inmeli hastaların ortaya çıkması, özellikle risk faktörlerinin eşlik ettiği durumlarda virüsün iskemik inmeye yol açtığı COVID-19 tedavisi sırasında veya tedaviden hemen sonra inmeli hastaların ortaya çıkması, özellikle risk faktörlerinin eşlik ettiği durumlarda virüsün iskemik inmeye yol açtığı hipotezini düşündürmektedir.
