Abstract:
Objective To evaluate MRI diagnostic value for single lesion characteristics in the splenium of corpus callosum.Methods MRI features,clinical data,and parts of follow-up results of 9 cases with single lesion in the splenium of corpus callosum were analyzed retrospectively.Results (1)Clinical manifestations:headache and dizziness occurred in 4 cases,syncope in 3 cases,fever in 2 cases, physical activity barriers in 2 cases.(2)Clinical diagnosis:hypoglycemic encephalopathy were rescaned one month later in 3 cases, in which the previous lesion completely disappeared.Clinical experience of encephalitis were improved after treatment in 2 cases. Cerebral infarction,epilepsy,brain injury and degeneration were diagnosed respectively in each one case,in which lesion still existed after treatmented.(3)Image findings:despite the different clinical manifestations,image features of all cases were quite similar. Round or foliated like lesions of slightly long T1 and long T2 signals in the splenium of corpus callosum were presented in all cases. High signals on diffusion weighted imaging and low signals on the ADC were showed with same lesions,andno obvious enhancement after contract media injected was seen.Conclusion Single lesions in the splenium of corpus callosum are showed in many diseases. The image features of hypoglycemic encephalopathy or encephalitis have certain characteristics (single lesion is reversible).Accurate diagnosis need to combine with clinical data and medical history.
