Abstract：Objective To study the magnetic resonance imaging(MRI)features and pathological findings of hippocampal sclerosis.Methods A total of 60 patients with hippocampal sclerosis were diagnosed as fluidattenuated inversion recovery(FLAIR),T1WI,T2WI and cross-sectional scan perpendicular to the long axis of the hippocampus.Results Results of the 60 patients,6 cases were bilateral hippocampal sclerosis and 54 cases were unilateral hippocampal sclerosis(23 cases on the left side,31 cases on the right),with all cases underwent surgical pathology.Sixty cases with 48 affected sides MRI showed atrophy of the affected hippocampus.T2WI(32 sides)and FLAIR imaging(35 sides)showed high signal,8 sides temporal lobe atrophy,17 sides temporal horn enlargement,12 ipsilateral white matter atrophy,the inner structure of the 29 affected hippocampal disappears,and the 20 superficial hippocampus of the affected hippocampus disappears.Conclusion MRI has a high diagnostic value for hippocampal sclerosis.The common MRI manifestations of hippocampal sclerosis are hippocampus atrophy and hippocampal increased signal,and the combination of FLAIR and T2WI can improve the accuracy and sensitivity of the diagnosis of hippocampal sclerosis.
