I62: Other nontraumatic intracranial haemorrhage

I62.1: Nontraumatic extradural haemorrhage

The brain is surrounded by various linings (meninges). The brain is also protected by the firm cranial bone. You have had a bleed between the meninges and the cranial bone.

There is not a lot of room in one’s head. When there is bleeding inside the head, the brain can become compressed. Brain tissue may be damaged as a result. This may cause one to have headaches or lose consciousness, for example.
