Abstract
BACKGROUND Relapsing or recurrent tumefactive demyelination is rare and has not been studied beyond individual case reports. OBJECTIVE We examined the clinical course, neuroimaging, cerebrospinal fluid (CSF), treatment and outcomes of patients with recurrent tumefactive demyelinating lesions (TDLs). METHODS We used PubMed to identify reports of recurrent TDLs and included the details of an additional, unpublished patient. RESULTS We identified 18 cases (11F, 7 M). The median age at onset of the index TDL was 37 years (range 12-72) and most were solitary lesions 72 % (13/18). CSF-restricted oligoclonal bands (OCBs) were detected in 25 % (4/16). Only one of those tested (n = 13) was positive for AQP4-IgG. A moderate-to-marked treatment response (high dose corticosteroid with or without additional plasmapheresis, IVIg or disease modifying therapies) was evident in 89 % of treated patients. Median EDSS at the median follow-up of 36 months (range 6-144) was 2 (range 1-10). Most remained ambulatory (EDSS < 4 in 13/18), but 1 patient died. CONCLUSION The median age of patients with relapsing TDLs is similar to that of typical MS, but differences include a lower female:male sex ratio, larger lesions, and a comparative lack of CSF-restricted OCBs. Outcomes vary among this group of patients ranging from minimal disability through to death.

Clinico-radiologic features and therapeutic strategies in tumefactive demyelination: a retrospective analysis of 50 consecutive cases. Ther Adv Neurol Disord 2021; 14:17562864211006503.

Abstract
Aims Our goal was to expand the spectrum of clinico-radiologic characteristics and the possible therapeutic choices in patients with tumefactive demyelinating lesions (TDLs). Methods A retrospective analysis of 50 patients with at least one TDL was performed at an academic neurology center (2008-2020). Results Our cohort comprised mostly women (33/50) with a mean age of 38 years at TDL onset. The mean follow-up time was 76 months. The mean Expanded Disability Status Scale score at TDL onset and at the latest neurological evaluation was 3.7 and 2.3, respectively. We subcategorized the patients into seven groups based mainly on the clinical/radiological findings and disease course. Group A included patients presenting with a Marburg-like TDL (n = 4). Groups B and C comprised patients presenting with monophasic (n = 7) and recurrent TDLs (n = 12), respectively. Multiple sclerosis (MS) patients who subsequently developed TDL (n = 16) during the disease course were categorized as Group D. Group E comprised patients who initially presented with TDL and subsequently developed a classical relapsing-remitting MS without further evidence of TDL (n = 5). Groups F (n = 2) and G (n = 4) involved MS patients who developed TDL during drug initiation (natalizumab, fingolimod) and cessation (interferon, fingolimod), respectively. Regarding long-term treatments applied after corticosteroid administration in the acute phase, B-cell-directed therapies were shown to be highly effective especially in cases with recurrent TDLs. Cyclophosphamide was spared for more aggressive disease indicated by a poor response to corticosteroids and plasma exchange failure. Conclusion Tumefactive central nervous system demyelination is an heterogenous disease; its stratification into distinct groups according to different phenotypes can establish more efficient treatment strategies, thus improving clinical outcomes in the future.

Abstract
PURPOSE OF REVIEW To review the clinical findings, differential diagnosis, treatment and outcome of pseudotumoral demyelinating lesions including tumefactive demyelination and Baló's concentric sclerosis. RECENT FINDINGS MRI findings, such as dynamic restricted diffusion changes at the edge of pseudotumoral lesions help to discriminate atypical demyelination from key differential diagnoses, and together with histopathological data, indicate that tissue hypoxia may be important aetiologically. CT-PET imaging can help to distinguish pseudotumoral lesions from high-grade tumours. Although most patients with pseudotumoral lesions have or later develop multiple sclerosis, a proportion will experience a monophasic course or be diagnosed with neuromyelitis optica spectrum disorders (NMOSD), myelin oligodendrocyte glycoprotein (MOG) antibody-associated demyelination or acute disseminated encephalomyelitis (ADEM). Many patients with pseudotumoral demyelinating lesions have a favourable prognosis. SUMMARY Not all patients with pseudotumoral lesions require a brain biopsy but close follow-up of biopsied and nonbiopsied lesions is indicated once a diagnosis is established. Testing for AQP4-IgG and MOG-IgG is recommended when a pseudotumoral demyelinating lesion is identified. In the absence of large, prospective studies, it seems reasonable that patients with pseudotumoral lesions who fulfil multiple sclerosis diagnostic criteria are treated with multiple sclerosis therapies.

A Blind Spot in the Diagnostic Field: The Challenging Diagnosis of Tumefactive Multiple Sclerosis. Case Rep Neurol Med 2018; 2018:6841291. [PMID: 30050706 PMCID: PMC6040262 DOI: 10.1155/2018/6841291] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2018] [Accepted: 06/07/2018] [Indexed: 11/18/2022] Open
Abstract
Tumefactive Multiple Sclerosis (TMS) is a rare variant with 1 per 1000 cases of MS and 3 per million cases per year. TMS can mimic clinical and radiological features of a neoplasm, infarction, or abscess and therefore can be diagnostically challenging for clinicians. We present a clinical scenario of a patient presenting with left homonymous hemianopia with atypical radiological features initially thought to be more consistent with neoplasm or infraction. Ultimately, biopsy was done which led to the diagnosis of tumefactive multiple sclerosis.
