It can be caused by a ruptured aneurysm (Fig. 2C), arteriovenous malformation (AVM), or head trauma.Bleeding within the brain tissue itself is known as an intracerebral hemorrhage (ICH) and is primarily caused by hypertension (Fig. 2D). Hypertension is an elevation of blood pressure which ...
Dandy–Walker malformation, Brain MRI (sagittal T2)Dandy–Walker malformation (DWM), also known as Dandy–Walker syndrome (DWS), is a rare congenital brain malformation in which the part joining the two hemispheres of the cerebellum (the cerebellar vermis) does not fully form, and the fourth ...
Imaging and other tests Depending upon the clinical situation, imaging of the brain such ascomputerized tomography(CT) andmagnetic resonance imaging(MRI) may be useful in making the diagnosis of a brain lesion. Angiographycan be added to either CT or MRI to visualize the blood vessels in the b...

Brain Arteriovenous Malformations (AVMs) Diagnosis of Intracerebral Hemorrhage Computed tomography (CT) or magnetic resonance imaging (MRI) is done immediately to confirm the diagnosis. Both tests can help doctors distinguish a hemorrhagic stroke from an ischemic stroke. The tests can also show how mu...
