Abstract:
Objective To explore the significance and value of loss of digitations of hippocampal head in diagnosis of hippocampal sclerosis.Methods Eighteen patients with hippocampal sclerosis comfirmed by histopathological examination and 18 cases to be matched control group were examined by MRI . The digitations,atrophic change and abnormal signals of hippocampal head were evaluated retrospectively.Results Of 18 patients with hippocampal sclerosis, loss of digitations was seen in 16 cases, poorly visible in 1 case and exist in 1 case. The sclerotic hippocampal heads all had atrophic change and were hyperintensity on T_2-weighted and FLAIR MR imagings. No loss of digitations were seen in the opposite side of the hippocampal sclerosis and all hippocampal heads in control group.Conclusion The loss of digitations of hippocampal head is a sensitive indicator for the diagnosis of hippocampal sclerosis.
