WebLarge intracerebral haemorrhage (ICH) A large area of increased density (white) represents acute bleeding into the brain parenchyma. Low density surrounding the blood indicates adjacent cerebral oedema. ICH is commonly associated with mass effect - this image shows effacement of the sulci and ventricles, and shift of midline structures. WebICH can also present as isoattenuation on CT, being difficult to distinguish from the brain parenchyma. Dual-energy CT can separate hemorrhage from other causes of hyperattenuation. Albeit, this type of technology has limited availability. Pitfalls on magnetic resonance imaging (MRI) are possible but less common.
