An Observational Study of Magnetic Resonance Imaging Evaluation of Encephalitis
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 2
Abstract
Objective: To evaluate the role of magnetic resonance imaging in encephalitis cases. Methods: The present descriptive study was carried out using a prospective study design. Age group included in the study was above 15 years. Patients clinically presenting with symptoms and signs suggestive of encephalitis were included in the study. MRI scan was performed in all patients. Results: The mean (±SD) age of the patients was 37.03 (±21.86) years. Thalami involvement was observed most commonly which is seen in 45% (18) case followed by Temporal lobe involvement in 42.5 %( 17), then Frontal lobe and Basal ganglia in 35%(14),Mid brain in 32.5%(13),Cerebellum in 30%(12),Pons and Medulla both in 27.5%(11),Parietal lobe in 17.5%(7), Occipital lobe 20%(8).Hence most common sites of brain involvement were thalami, temporal lobe, frontal lobe and basal ganglia. Conclusion: Suggestive MRI findings are present in some etiologies of viral encephalitis such as Herpes simplex encephalitis, JE, enterovirus encephalitis MRI may show non-specific features of viral encephalitis such as cortical hyperintensities and cerebral edema. MRI is also useful for diagnosing alternative etiologies such as Acute disseminated encephalomyelitis, and antibodyassociated encephalopathies.
