Disproportionate subarachnoid space hydrocephalus—outcome and perivascular space

OBJECTIVE We sought to identify the prevalence of MRI features of disproportionately enlarged subarachnoid space hydrocephalus in possible idiopathic normal pressure hydrocephalus (DESH-iNPH) and to describe the clinico-radiological features and outcomes of a community-based investigation (The Vienna Trans-Danube Aging study). METHODS Of the 697 inhabitants (all 75 years old), 503 completed e...

Blood in the subarachnoid space.

Blood is a potent irritant to nervous tissue and alone can cause arachnoiditis. In combination with chemical substances, the risk is magnified. This was first noted in relation to oil-based myelographic dyes by Howland and Curry ( [1] ) who found that in dogs, blood and dye together caused severe adverse effects. Hence dural puncture during epidural administration of drugs should be treated ser...

Enlarged perivascular space mimicking mesencephalothalamic cystic tumor

Perivascular spaces (PVSs) of the brain, also known as Virchow-Robin spaces are pial-lined interstitial fluidfilled structures that surround the small vessels as they extend into the brain parenchyma. PVSs, which are smaller than 2 mm can be seen in all age groups.1,2 Occasionally, PVSs may become large, cause mass effect and be misdiagnosed as a cystic neoplasm. These giant spaces are most com...

Cerebrospinal Fluid Flow Analysis in Subarachnoid Space

A better understanding of the hydrodynamics of the cerebrospinal fluid (CSF) is important to understand the pathophysiology of various diseases related to the central nervous system (CNS). This project aims to simulate the CSF flow in subject specific subarachnoid spaces (SAS) of healthy volunteers and patients suffering from Chiari malformation. The simulations at high spatial and temporal res...
