intracranial hemorrhage

noun

: bleeding from a ruptured blood vessel within the cranium

Note: An intracranial hemorrhage may occur within the brain (see cerebral hemorrhage) or occur in the space between the brain and skull where the accumulation of blood may cause brain damage by increasing pressure on the brain tissue.

The drawback of the drugs is that they promote bleeding and raise the odds of a potentially fatal stroke from an intracranial hemorrhage.

Images from CT of the head performed the next day show progressive edema but no new intracranial hemorrhage.
