Intra-axial hematoma

Overview
Intra-axial hemorrhages, or intra-axial hematomas, are a subtype of intracranial hemorrhage that occur within the brain tissue itself.

Intra-axial hemorrhages are potentially deadly because they can increase intracranial pressure and crush delicate brain tissue or reduce its blood supply, causing ischemia. The other category of intracranial hemorrhage is extra-axial hemorrhage, such as epidural, subdural, and subarachnoid hematomas, which all occur within the skull but outside of the brain tissue.

There are two main kinds of intra-axial hemorrhages: intraparenchymal hemorrhage and intraventricular hemorrhages.
