CT/MRI and Clinical Findings of Non-hemorragic Contusion of Corpus Callosum

<b<Objective:</b< To study MRI findings of non-hemorragic contusion of corpus callosum. <b<Methods:</b< The CT and MR images of non-hemorragic injury of corpus callosum were reviewed retrospectively. All patients were examined with CT and MR imaging within 0.5h to 3d. <b<Results:</b< There was no abnormal signs of corpus callosum on CT images. MR study in all 8 cases demonstrated isointense or slight hypointense signal on T<sub<1</sub<WI and obvious hyperintense signal on T<sub<2</sub<WI. There was no hemorragic signal or density on MR and CT at corpus callosum. These contusion lesions were revealed more clearly high signal intensity on FLAIR sequence. These lesions were located at splenium(2 cases), genu(4 cases), rostrum(1 cases) and splenium-body(1 cases). Several other multiple contusion and hemorragic lesions were detected in all 8 cases. <b<Conclusion:</b< MRI is superior to CT on detecting non-hemorragic contusion of corpus callosum. It can provide useful supportive information for clinical diagnosis and therapy.
