Neuroimaging in epilepsy: Magnetic resonance imaging (MRI) evaluation in refractory complex partial seizures

Aim: to describe various types of epileptogenic lesions causing seizures in adults on mri. methods: this case series descriptive study was conducted in department of diagnostic imaging in lahore general hospital,lahore. sixty adult patients of seizures were included in the study. the optimum protocol was axial t1weighted and axial t2-weighted,coronal t1-weighted/ coronal t2-weighted images,and nonenhanced fluid attenuated inversion recovery sequence images. results: out of sixty patients,50 patients (83.3%) were found to have epileptogenic lesion,10 patients (16.7%) were having normal mri. 32 (53.3%) were male and 28 (46.7%) were females. majority belongs to age group 21 to 30 years. common types of seizures were complex partial seizures 53.3%. common epileptogenic lesions identified were tumors 33.3%,focal cortical dysplasia 10%,mesial temporal sclerosis 13.3%,infarcts 13.3%,metastasis 6.7% and granulomas 6.7%. ventricular compression was seen in 40% of patients having epileptogenic lesion. conclusion: mri is an important and reliable tool to diagnose most of epileptogenic lesions causing seizures.
