Cavernous Haemangioma of Brain
نویسنده
چکیده
MRI is the most important imaging study for confirmation of the diagnosis (figure 2). In the absence of overt haemaorrhage, most CHs appear as a hyperintense lesion with a faint hypointense rim in T1 and lobulated heterogenous signals with a hypointense rim in T2. The most diagnostic image appears in the gradient-echo MRI which produces a blooming artifact from the magnetic susceptibility effect of haemosiderin. CH therefore appears characteristically as a dense hypointense signal in the gradient-echo MRI.
