Affected Side

Background: Trigeminal neuralgia (TN) is a severe neuropathic unilateral facial pain affecting about 30% percent of the world population. Neuropathic pains are considered to be associated with multiple sclerosis (MS).Multiple sclerosis is a chronic inflammatory condition causing demyelination and degeneration of axons in central nervous system. Objective: The objective of the study is to determine role of Magnetic Resonance Imaging to find association between trigeminal neuralgia and multiple sclerosis. Methods: The prospective cohort study was conducted for six months in Radiology Department of Hayatabad Medical Complex, Peshawar from September 2020 to February 2021. Initially 250 patients were screened for multiple sclerosis. The study recruited a total of 35 patients of MS visited neuroradiology department, out of which 26 patients were enrolled in the study. The participants with age of 18 years and onward of both genders with definitive symptoms of TN with MS that is having unilateral TN pain (that is sharp shooting electric pulse like) lasting for up-to 2minutes precipitated with an environmental stimulus were included in the study. The patients (n=6) with bilateral MS with TN and cognitive disturbances (n=3) were excluded from the study. Results: The study recruited a total of 26 participants with MS related TN. The clinical examination didn’t show any difference between the three groups with the p-value less than 0.001. Age at the onset of MS was younger in patients with MS related sensory disturbances compared to other two groups, with p-value less than 0.05. The frequency of the affected side was different in all three groups with the p-value less than 0.05 as tested by Fischer exact test. Trigeminal reflex tests done for different components such as R1 and SP1 showed longer latency periods for the affected side after stimulation and unaffected side after stimulation with the mean of 14.2± 4.4 and 15.3±3.2, 16.3±4.2 and 17.4±5.2ms and p-value less than 0.001 as shown by Wilcoxon test. Conclusion: The study showed significant association between trigeminal neuralgia and multiple sclerosis with the greater efficacy of using MRI as imaging technique to find this association.

Background: Accurate classification of multiple sclerosis (MS) lesions in the brain cortex may be important in understanding their impact on cognitive impairment (CI). Improved accuracy in identification/classification of cortical lesions was demonstrated in a study combining two magnetic resonance imaging (MRI) sequences: double inversion recovery (DIR) and T1-weighted phase-sensitive inversion recovery (PSIR). Objective: To evaluate the role of intracortical lesions (IC) in MS-related CI and compare it with the role of mixed (MX), juxtacortical (JX), the sum of IC + MX and with total lesions as detected on DIR/PSIR images. Correlations between CI and brain atrophy, disease severity and disease duration were also sought. Methods: A total of 39 patients underwent extensive neuropsychological testing and were classified into normal and impaired groups. Images were obtained on a 3T scanner and cortical lesions were assessed blind to the cognitive status of the subjects. Results: Some 238 cortical lesions were identified (130 IC, 108 MX) in 82% of the patients; 39 JX lesions were also identified. Correlations between CI and MX lesions alone ( p = 0.010) and with the sum of IC + MX lesions ( p = 0.030) were found. A correlation between severity of CI and Expanded Disability Status Scale was also seen ( p = 0.009). Conclusion: Cortical lesions play an important role in CI. However, our results suggest that lesions that remain contained within the cortical ribbon do not play a more important role than ones extending into the adjacent white matter; furthermore, the size of the cortical lesion, and not the tissue-specific location, may better explain their correlation with CI.
