BACKGROUND: Virchow Robin spaces (VRSs) are perivascular spaces that act as drainage pathways for interstitial fluid. Dilatation of VRSs is visible on magnetic resonance images in asymptomatic individuals. However, giant dilatation of VRSs (dVRSs) is very rare. Such giant dVRSs may produce a pressure effect on surrounding structures and can be confused with more sinister conditions such as @entity5 . CASE DESCRIPTION: We describe a 30-year-old @entity1 who presented with complaints of @entity10 , poor attention and concentration, forgetfulness, @entity2011 , urinary incontinence for past 3 years and @entity2147 for 3 months. He was found to have a @entity75 in the midbrain with extension into the third ventricle, causing @entity1276 due to @entity8468 . Although at first look, the radiologic features suggested a @entity5 , a careful magnetic resonance imaging evaluation helped to establish the correct diagnosis of dVRS. Endoscopic third ventriculostomy resolved his symptoms. CONCLUSIONS: Dilatation of VRS may produce @entity75 that can easily be confused with other pathologic condition that have a completely different prognosis and management. Knowledge about the existence of such an entity and their radiologic features is important to prevent such misdiagnosis and mismanagement in the form of biopsy/excision, which can have devastating consequences.
