'''Tumefactive multiple sclerosis''' ('''TMS''') is a rare form of [[multiple sclerosis]] characterized by mass-like lesions or [[tumor]]-like lesions in the [[brain]]. It is often mistaken for a [[brain tumor]] or [[abscess]] due to its similar appearance on [[magnetic resonance imaging]] (MRI) scans.

A rare form of multiple sclerosis


Tumefactive multiple sclerosis is a rare form of multiple sclerosis (MS) characterized by large lesions in the central nervous system that resemble tumors. These lesions are typically larger than two centimeters and can mimic the appearance of a glioblastoma or other types of brain tumors on magnetic resonance imaging (MRI) scans.

Presentation[edit]

Patients with tumefactive multiple sclerosis often present with symptoms similar to those of a brain tumor, including headaches, seizures, cognitive impairment, and focal neurological deficits. The condition can be challenging to diagnose due to its similarity to other neurological disorders.

Diagnosis[edit]

The diagnosis of tumefactive multiple sclerosis is primarily based on neuroimaging techniques, particularly MRI. The lesions in tumefactive MS are typically large, with edema and mass effect, and may show ring enhancement after the administration of contrast agents. A biopsy may be necessary to differentiate tumefactive MS from other conditions such as glioblastoma or abscesses.

Pathophysiology[edit]

The exact cause of tumefactive multiple sclerosis is not well understood, but it is believed to involve an aggressive inflammatory process within the central nervous system. Like other forms of MS, it is thought to be an autoimmune disease where the body's immune system attacks the myelin sheath surrounding nerve fibers.

Treatment[edit]

Treatment for tumefactive multiple sclerosis often involves high-dose corticosteroids to reduce inflammation and edema. Other treatments may include plasmapheresis or immunosuppressive therapy. The management of tumefactive MS can be complex and may require a multidisciplinary approach.

Prognosis[edit]

The prognosis for individuals with tumefactive multiple sclerosis varies. Some patients may experience a single episode with complete recovery, while others may develop relapsing-remitting multiple sclerosis or primary progressive multiple sclerosis.
