Three Cases of Demyelinating Disease mimicking Primary Brain Tumor

Inflammatory demyelinating diseases are usually diagnosed based on characteristic clinical and radiological findings. However, some demyelinating diseases have been presented as growing large mass-like lesions, and it is difficult to differentiate those demyelinating lesions from brain tumors. We report three cases of demyelinating diseases mimicking brain tumors. These cases suggest that the inflammatory demyelinating diseases have a wide spectrum and they can present with the same radiological features of brain tumors.
