Fig 4. A 22-year-old female patient with familial CCM. A, Axial T2-weighted FSE image shows a large right temporal lesion with mixed signal intensity (type II). B, T2-weighted GRE image demonstrates this lesion and, in addition, a small focus of low signal intensity on the right occipital lobe (arrow). C, SWI shows a small focus of low signal intensity on the right temporal region (arrow), which is dissociated from the large lesion (bloom effect).
