Objective To explore the clinical value of susceptibility weighted imaging (SWI) in the diagnosis of secondary epilepsy. Methods Ten epilepsy patients were collected and underwent routine MRI and SWI scans,all of them had normal CT scan and abnormal electroencephalogram. Results Four of ten patients’ cranial MRI and SWI scans prompted normal. Six of ten patients’ were abnormal, in which four were cerebral venous malformation, dilated pulp veins and gross draining vein were all clearly shown by SWI, low signal and typical "caput medusae" sign was shown; Two of six were cavernous hemangioma, the lesion center for mixed signals of low and high and typical “iron ring” sign around were shown by SWI. Conclusion Susceptibility weighted imaging has obvious advantages in diagnosis of secondary epilepsy, and more sensitive to show the typical image of cerebral venous malformation and cavernous hemangioma than ordinary MRI sequence.
