The overall incidence of intracerebral hemorrhage has declined since the 1950s.Annually, more than 20,000 individuals in the United States die of intracerebral hemorrhage. A, Coronal graphic demonstrates the normal splitting of the periosteal/endosteal (outer dura) and (inner) meningeal dura (black arrows) to encompass the superior sagittal dural venous sinus.Also note the penetration of a bridging vein through the dural wall of the venous sinus (white arrow).Hallevi et al reviewed the charts and CT scans of patients with intraventricular hemorrhage (IVH) to determine if the extension of the hemorrhage could be measured.Clinical outcome was determined by the modified Rankin Scale (m RS). The IVH score allowed rapid estimate of IVH volume by the practitioner and increased predictability for outcome.The composition of this inner DBCL is unique in three ways.

Clinical neuropathologic observations that support a tight relationship between the arachnoid barrier cells and DBCL layer include: (1) SDHs are not always associated with subarachnoid hemorrhage (SAH) (unless there is tearing of arachnoid vessels including cortical dural bridging veins); (2) purulent meningitis remains confined to the SAS and rarely is associated with subdural empyema; (3) SAS hemorrhage, as might be seen with ruptured aneurysm, does not typically extravasate into the subdural compartment (pers. The separation between these two cellular planes creates what is commonly known as the The arachnoid mater and the pia mater are normally interconnected by a honeycomb network of trabeculae.

Intracranial hemorrhage (ie, the pathological accumulation of blood within the cranial vault) may occur within brain parenchyma or the surrounding meningeal spaces.

Hemorrhage within the meninges or the associated potential spaces, including epidural hematoma, subdural hematoma, and subarachnoid hemorrhage, is covered in detail in other articles.
