MRI characteristics of paraneoplastic limbic encephalitis. MRI brain showing uniform bilateral symmetric restricted diffusion, hyperintensity and avid post-contrast enhancement involving the bilateral caudate (A), globus pallidus (A), and cerebellum (B) (DWI diffusion-weighted imaging, ADC apparent diffusion coefficient, FLAIR fluid-attenuated inversion recovery). Mild right posterior scalp edema noted here is thought to be related to self-injurious behavior as it resolves in subsequent MRIs and is not commented on by reading radiologist
