A: Artist rendition of the mulberry-like CA. B: 3D MRI slab of a human lesion, T2 acquisition at 3 Tesla, highlighting the characteristic “popcorn appearance” of a CA with a hemosiderin ring. C: Confocal immunofluorescence photomicrograph with staining (CD31, green) of endothelial cells (ECs) lining the lesion’s vascular spaces (caverns). Red blood cells (red) fill the caverns and extravasate beyond the “leaky” endothelium. Bar = 40 μM. D: Comparative image of normal brain capillaries. Bar = 20 μM.
