A subdural hygroma (SDG) is a collection of cerebrospinal fluid (CSF), without blood, located under the dural membrane of the brain. Most subdural hygromas are believed to be derived from chronic subdural hematomas. They are commonly seen in elderly people after minor trauma, but can also be seen in children following infection or trauma.

In chronic subdural hematomas, blood accumulates in the dural space as a result of damage to the dural border cells. [16] The resulting inflammation leads to new membrane formation through fibrosis and produces fragile and leaky blood vessels through angiogenesis , permitting the leakage of red blood cells , white blood cells , and plasma into ...
Subdural hemorrhage (SDH) results from tearing of the bridging veins in the subdural space between the dura and arachnoid mater. It can cross the suture lines, but not across dural reflections such as falx cerebri or tentorium cerebelli. [4] Therefore, subdural hematoma always limited to one side of the brain. [3]
In some circumstances, concussive injury can cause microvascular disruption, hemorrhage, or subdural hematoma. [7] [10] Closed head injury (coup contrecoup) can damage more than the impact sites on the brain, as axon bundles may be torn or twisted, blood vessels may rupture, and elevated intracranial pressure can distort the walls of the ...
For a new show at the Rochester Art Center, 13 Minnesota artists have put their experiences into art as part of a group exhibition called "Chronicles of the Chronic." The gallery opened Sept. 2 ...
Hemosiderin deposition in the brain is seen after bleeds from any source, including chronic subdural hemorrhage, cerebral arteriovenous malformations, cavernous hemangiomata. Hemosiderin depositionon on the surface of the brain and spinal cord due to chronic bleeding in the subarachnoid space is known as superficial siderosis.
The New York Mets bolstered their bullpen on Thursday, finalizing a one-year contract with right-hander Ryne Stanek. Stanek was acquired in a trade with Seattle at the deadline last year for minor ...
