Multiple Sclerosis causes lesions to form in the affected part of the body. Tumefactive demyelination and pontine demyelination are types of these lesions.

Tumefactive Demyelination

These are lesions of more than 2 cm in size with the presence of mass effect, edema or ring enhancement. The characteristics of Tumefactive Demyelination can mimic other diseases and can even lead to wrong diagnosis. Often, it requires a brain biopsy to arrive at the right diagnosis.
