"Non-traumatic (spontaneous) intracerebral haemorrhage accounts for approximately 10–20% of all strokes 13. The total incidence of intracerebral haemorrhage is ~30 per 100,000 person-years 25, with incidence rates showing great variability across different ethnicities 13. The incidence rises with age with men at higher risk compared to women 25,26."
"the volume of an intracerebral haemorrhage can be measured using ABC/2 formula or 3D volumetric software"
"the ABC/2 formula is widely used, but there may be more accurate formulas (e.g. 2.5ABC/6, SH/2) and analyses available, some of which, however, may require the addition of specific software to the standard PACS tools"

"This article concerns non-traumatic intracerebral haemorrhages; traumatic haemorrhagic cerebral contusions are discussed separately."
"intraventricular haemorrhagic extension occurs due to decompression of the haemorrhage into the low resistance ventricular system, thus; haematomas located in the thalamus, caudate nucleus or pons are more prone to intraventricular extension than lobar haematomas"
"Intracerebral haemorrhages arise from rupture of a small blood vessel within the brain parenchyma or, less commonly, of a blood vessel adjacent to the parenchyma (e.g. jet haematoma)."
"vascular malformation (e.g., brain arteriovenous malformation, cerebral cavernous malformation)"
"tumour (e.g., metastases, glioblastoma)"
"bleeding diathesis (e.g., anticoagulation therapy)"
"Findings depend on the size and age of the bleed (see ageing blood on MRI). MRI may also reveal clues to the aetiology, such as those of cerebral small vessel diseases (e.g. hypertensive microangiopathy, cerebral amyloid angiopathy)."
