The MRI Findings in Complex Partial Seizure Disorders

ABSTRACT

This study was performed to evaluate, in complex partial seizure, the incidence and nature of MRI abnormality and the correlation between MRI and interictal nasopharyngeal EEG findings. MRI findings were also correlated with age of seizure onset, duration and clinical response to anticonvulsants. For this study, high field MR imaging and interictal nasopharyngeal EEG were performed in 122 patients with complex partial seizures. The patients were distributed in all age groups(mean age26 years) and include 64 males and 58 females. The average duration of seizure disorder was 10.8 years. Abnormal MRI findings were discovered in 74 of 122 patients, in which mesial temporal sclerosis was most common(58.1%). And other abnormalities were neuroglial tumor(l3.5%), infectious lesion (10.8%), vascular lesion (6.8%), hemiatrophy (4.19@), cystic mass (2.7%) and others (4.1%). There were only slight difference in seizure duration(p0.1).
