Intraparenchymal haemorrhage (IPH). A coloured computerized tomography (CT) scan of an axial section of the brain of a 37-year-old patient with arterial hypertension (high blood pressure). This patient experienced a severe headache before entering into a comatose state (can be caused by the brain swelling in severe cases of arterial hypertension). There is a large intraparenchymal haemorrhage (orange, a form of intracerebral bleeding from within the brain parenchyma) on the right side of the parieto-occipital region of the brain. Intracerebral haemorrhages, and accompanying oedema, can disrupt and compress adjacent brain tissue, which leads to neurological disorders. A craniotomy is sometimes done to remove blood from the haemorrhage, and other medications may be prescribed to reduce swelling, and lower blood pressure. This is a CT scan without intravenous iodine injection.
