Multiple Sclerosis

The set of cranial MRIs shown here are from a young woman with a known history of relapsing-remitting multiple sclerosis. In the first scan (T2W axial cut), we can see multiple T2 hyperintense lesions involving bilateral cerebral cortices arrow_1 (Figure 1). These lesions are noted to be of a juxta-cortical and also peri-ventricular distribution, which are classical of multiple sclerosis. In the next scan (FLAIR sequence, coronal cut, Figure 2), additional hyperintense lesions could be seen at the juxta-cortical region of the right parietal lobe arrow_1 as well as at the left pons arrow_1. The right parietal lesion is noted to be contrast enhancing in the final scan which is a T1W sequence with contrast arrow_1 (Figure 3). The patient had presence of oligoclonal bands in the cerebrospinal fluid and is currently on β-interferon for prevention of relapses.
