Stereotactically Treated Giant Perivascular Spaces in a 13-Year-Old Boy Mimicking Brain Tumor

Introduction

Perivascular spaces (PVSs) of the brain, also known as Virchow-Robin spaces, are pia-lined cavities surrounding brain arteries and arterioles as they penetrate into the cerebral tissue [13] [16]. Cystic cavities have first been described in the literature in 1838, as small cavities in the globus pallidus and putamen [2].

In most patients, enlarged perivascular spaces do not cause neurological symptoms. In some patients, they can cause focal neurological symptoms and an extensive space-occupying effect which requires neurosurgical intervention [1] [6] [7] [17].
