Type 2 cavernous angioma in an asymptomatic 24yearold man. (a) Transverse T1weighted SE MR image shows a cavernous angioma in the right cingulate gyrus. The lesion includes a central reticulated core (arrow) and a peripheral lowsignalintensity rim (arrowhead). (b) Transverse T2weighted fast SE MR image helps confirm the presence of a type 2 cavernous angioma in the right cingulate gyrus. The lesion has a core of heterogeneously high signal intensity (straight arrow) an
