We describe a case of a 50-year-old female with incidental giant Virchow-Robin spaces in the right hemispheric subcortical white matter with adjacent white matter hyperintense signal intensity on T2-weighted and FLAIR images.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Perivascular spaces surround the small arteries and veins as they enter into the brain parenchyma from the subarachnoid spaces.
📊
Key Findings & Data:Typically there is no significant adjacent brain abnormality; however FLAIR images may sometimes reveal perilesional white matter hyperintensity, which may be an indication of gliosis due to the mass effect of the lesion.
💡
Conclusion & Impact:We describe a case of a 50-year-old female with incidental giant Virchow-Robin spaces in the right hemispheric subcortical white matter with adjacent white matter hyperintense signal intensity on T2-weighted and FLAIR images.

Abstract

Perivascular spaces surround the small arteries and veins as they enter into the brain parenchyma from the subarachnoid spaces. Also called as Virchow-Robin spaces, these are prominent in the basal ganglia and high convexity white matter of the elderly. Occasionally VR spaces may get massively enlarged and may mimic a cystic mass lesion. The typical CSF-like signal intensity of the cysts and location on MRI, in the absence of a neurological abnormality help in the diagnosis of the giant VR spaces and thus biopsy is avoided. Typically there is no significant adjacent brain abnormality; however FLAIR images may sometimes reveal perilesional white matter hyperintensity, which may be an indication of gliosis due to the mass effect of the lesion. Such a signal alteration should not deter one from making a diagnosis of giant Virchow-Robin spaces when the rest of the imaging findings are typical. We describe a case of a 50-year-old female with incidental giant Virchow-Robin spaces in the right hemispheric subcortical white matter with adjacent white matter hyperintense signal intensity on T2-weighted and FLAIR images.

Özet

Subaraknoid boşluklardan beyin parenkimine girdikleri zaman küçük arter ve venleri perivasküler boşluklar sarar. Virchow-Robin boşlukları olarak da isimlendirilen bu boşluklar yaşlılarda bazal ganglialarda ve yüksek konveksite beyaz maddede belirgindir. Zaman zaman bu VR boşlukları çok büyüyebilirler ve kistik kitle lezyonlarını taklit edebilirler. Bu kistlerin tipik BOS benzeri sinyal özellikleri ve MRG deki yerleşimleri, nörolojik anomali yokluğunda dev VR boşluklarının teşhisinde yardımcı olur ve böylece biyopsiden kaçınılabilir. Tipik olarak komşu beyinde belirgin bir anomali yoktur fakat FLAİR görüntüler bazen beyaz madde perilezyonel hiperintensitesi gösterebilir ki bu da lezyonun kitle etkisine bağlı gliozisin bir göstergesidir. Böyle bir sinyal değişikliği diğer görüntüleme bulguları tipik olduğunda Virchow-Robin boşlukları teşhisinin konulmasını engellememelidir. Biz T2 ağırlıklı ve FLAİR görüntülerde komşu beyaz madde hiperintens sinyal intensitesi gösteren sağ hemisferik subkortikal beyaz madde dev Virchow-Robin boşlukları insidental olarak saptanan 50 yaşında bir bayan hasta sunuyoruz.
