A Case of Multiple Sclerosis Presenting with Tumefactive Lesions

Abstract

Inflammatory demyelinating diseases including multiple sclerosis (MS) are usually diagnosed based on characteristic clinical and radiological findings. However, some demyelinating diseases have presented with growing large mass-like lesions, and it is difficult to differentiate those demyelinating lesions from brain tumors. We report a case of biopsy-proven MS mimicking brain tumor. This case suggests that inflammatory demyelinating diseases including MS have a wide spectrum and can present with the same radiological features as brain tumors such as lymphoma or high-grade glioma.
