Dilated Virchow Robin spaces in brainstem

Abstract

Virchow Robin spaces are normally found pial-lined perivascular spaces traversing from subarachnoid space to the brain parenchyma. Giant dilated Virchow robin spaces (dVRS) are rare. They do not require any surgical intervention unless they are causing symptoms. Here we report a young boy with an incidentally detected giant dVRS in brainstem which was referred for surgery with an initial impression of glioma. Knowledge about such an entity is important to prevent mismanagement.
