A small amount of bleeding can absorb itself and heal on its own.
However, if the haematoma has a significant occupying effect, with supratentorial haemorrhage greater than 30ml, subatentorial haemorrhage greater than 10ml or if brain herniation is present, emergency surgery is required. An intracranial haematoma is a collection of blood from a ruptured blood vessel in the brain or between the brain tissue and the skull following a brain injury, which can cause compression of the brain tissue and is a more serious condition requiring prompt treatment. Conservative in-hospital treatment is available for awake patients with minimal bleeding and minor cranial injury, with symptomatic haemostasis, cranial pressure lowering and close observation of the condition.
