Multiple Sclerosis-Minimizing Errors in Radiological Diagnosis

Background: Multiple sclerosis is a chronic demyelinating disorder with a myriad of imaging and clinical features that overlap with number of other neurological conditions. Incorrect diagnosis poses a significant risk to patients, it may lead to delays in management, increased morbidity, and also adds to the financial cost. Objective: The aim of this study was to highlight strategies for the efficient differentiation of multiple sclerosis from other diseases which may masquerade as MS clinico-radiologically. Material and Methods: A systematic literature review was conducted through online databases including PubMed and Medline. Relevant publications on radiological aspects of multiple sclerosis, white matter diseases and mimickers of Multiple sclerosis were included in the analysis. Results: Common mimickers of MS include small vessel disease, acute disseminated encephalomyelitis, neuromyelitis optica, anti-MOG encephalomyelitis, vasculitis, and CADASIL. Contrast-enhanced MRI study performed using MS protocol on high strength MRI system evaluated following a structured protocol along with clinical correlation is effective in differentiating MS from its mimickers. Conclusions: Contrast-enhanced MRI performed on a high strength scanner using MS protocol with structured protocol for evaluation along, with a better collaboration between radiologists and clinicians may help in minimizing errors in diagnosis of multiple sclerosis.
