Abstract:
Magnetic resonance imaging (MRI) examination was performed in 18 patients with complex partial seizures (CPS) of long duration, who had normal computerized tomographic (CT) scans of the brain. Small MRI abnormalities correlating with the location of the epileptogenic focus in the EEG were demonstrated in 4 cases. The findings with strong signals were better demonstrated in the coronal view with longer time to echo (TE). In one patient, a lower signal lesion was documented, which was better visualized in the axial view with shorter TE. Patients with CPS should be subjected to MRI examinations with coronal and sagittal planes, using short and long TE in each slice. This method minimizes the chance for missing pathology.
