They are also found in Cisterna magna Pontine cistern Interpeduncular cistern Chiasmatic cistern Of lateral cerebral fossa Superior cistern Of lamina terminalis. Dilation is a typical characteristic of several diseases and disorders. Journal of Cerebral Blood Flow and Metabolism. These include diseases from metabolic and genetic disorders such as mannosidosismyotonic dystrophyLowe syndromeand Coffin—Lowry syndrome.
Because dilated perivascular spaces are so closely correlated with cerebrovascular diseasethere is much current research on their use as a diagnostic tool. A special type of perivascular space occurs in the anterior temporal lobe and can mimic a cystic tumor. When located in the anterior temporal lobe and related to a vascular loop, they are known as anterior temporal lobe perivascular spaces ; however, these likely represent a different entity compared to typical scattered perivascular spaces.

The spaces appear as distinct round or oval entities with a signal intensity visually equivalent to that of cerebrospinal fluid in the subarachnoid space. Perivascular spaces are very common, and increasingly seen with better MRI image resolution.
These are discussed separately: Often, cell debris and foreign particles, which are impermeable to the BBB will get through the endothelial cells, only to be phagocytosed in the rkbin spaces. Dilated perivascular spaces are categorized into three types: Journal of the Neurological Sciences.
