Balo’s concentric sclerosis in a patient with spontaneous remission based on magnetic resonance imaging: A case report and review of literature

Figure 3 Apparent diffusion co-efficient maps portraying only a thin rim of restricted diffusion at the outer rim of the lesion, with facilitated diffusion centrally and at the outer edema. A: Diffusion weight images shows a thin rim of increased diffusion at the outer rim of the lesion; B: The outer rim is hypointense on the corresponding apparent diffusion coefficient map images, indicating true restriction.
