Intracerebral haemorrhage

An intracerebral haemorrhage, or intraparenchymal cerebral haemorrhage, is a subset of an intracranial haemorrhage. This can encompass a number of entities that share the acute accumulation of blood in the parenchyma of the brain. The aetiology, epidemiology, treatment and prognosis vary widely depending on the type of haemorrhage, and as such these are discussed separately. 

Types of intracerebral haemorrhage include (see related articles for full list):

Practical points

With any intracerebral haemorrhage the following points should be included in a report as they have prognostic implications 3:

  • location
  • size/volume
    • the ABC/2 formula is widely used, but there may be more accurate formula (e.g. 2.5ABC/6, SH/2) and analyses available, some of which may require addition of specific software to the standard PACS
  • shape (irregular vs regular)
  • density (homogeneous vs heterogeneous)
  • presence/absence of intraventricular haemorrhage
  • presence/absence of hydrocephalus
  • when CTA performed, the presence/absence of the CTA spot sign or a vascular malformation
