ABSTRACTBalo's concentric sclerosis (BCS) is a rare demyelinating lesion considered to be a variant of multiple sclerosis (MS). On magnetic resonance imaging (MRI) Balo's concentric sclerosis shows the typical concentric pattern. We report a case of 10 year old child with BCS who presented as post infectious acute disseminated encephalomyelitis (ADEM). He is asymptomatic and had no relapse after 6 years of follow-up.

Secondary paroxysmal dyskinesias (SPDs) are short, episodic, and recurrent movement disorders, classically related to multiple sclerosis (MS). Carbamazepine is effective, but with risk of adverse reactions. We identified 7 patients with SPD among 457 MS patients (1.53%). SPD occurred in face ( n = 1), leg ( n = 2), or arm +leg ( n = 4) several times during the day. Magnetic resonance imaging (MRI) showed new or enhancing lesions in thalamus ( n = 1), mesencephalic tegmentum ( n = 1), and cerebellar peduncles ( n = 5). Patients were treated with clonazepam and then acetazolamide ( n = 1), acetazolamide ( n = 5), or levetiracetam ( n = 1) with response within hours (acetazolamide) to days (levetiracetam). No recurrences or adverse events were reported after a median follow-up of 33 months.

One prognostic factor for early multiple sclerosis (MS) patients to develop a definite MS may be the presence of the MS-associated retrovirus (MSRV) in the cerebrospinal fluid (CSF). We designed a specific study on a cohort of optic neuritis (ON) patients to evaluate the MSRV-dependent conversion to MS relative to the prediction conferred by magnetic resonance imaging (MRI) and CSF abnormalities. At follow-up, 33.3% MSRV+ and 0% MSRV− ON patients developed MS ( P=0.03). The prediction value is lower than that given by CSF and MRI abnormalities (42.3%). This intriguing finding is discussed in the light of the abundant discrepancies observed in the MSRV literature.

The acute disseminated encephalomyelitis ADEM is a rare form of encephalitis. We report a case after herpes infection. The diagnosis was based on the existence of post-infectious and neurological signs and demyelinating reaching the white matter in the magnetic resonance imaging MRI. The outcome was favourable after treatment with high-dose steroids.

Background: New inflammatory activity is of unclear frequency and clinical significance in progressive multiple sclerosis (MS); it is uncertain in patient cohorts with motor progression due to critical demyelinating lesions. Objectives: The aim of this study is to determine the likelihood of central nervous system (CNS) inflammatory activity, assessed by new clinical relapses or active magnetic resonance imaging (MRI) lesions, following onset of motor progression due to critical demyelinating lesions. Methods: Patients with progressive upper motor neuron impairment for ⩾1 year attributable to critical demyelinating lesions with single CNS lesion (progressive solitary sclerosis (PSS)), 2 to 5 total CNS demyelinating lesions (progressive “pauci-sclerosis” (PPS)), or >5 CNS demyelinating lesions and progressive exclusively unilateral monoparesis or hemiparesis (PUHMS) were identified. Clinical data were reviewed for acute MS relapses, and subsequent MRI was reviewed for active T1-gadolinium-enhancing or T2-demyelinating lesions. Results: None of the 91 patients (22 PSS, 40 PPS, 29 PUHMS) identified experienced clinical relapses over a median clinical follow-up of 93 months (range: 12–518 months). Nine patients (10%) developed active lesions over median 84 months radiologic follow-up (range: 12–518 months). Active lesions occurred in 24% PUHMS, 5% PSS, and 3% PPS cohorts. Conclusion: New inflammatory activity, defined by active lesions and clinical relapses following motor progression in patients with critical demyelinating lesions, is low. Disease-modifying therapies that reduce demyelinating relapses and active MRI lesions are of uncertain benefit in these cohorts.

Acute disseminated encephalomyelitis (ADEM) is an inflammatory demyelinating disease of the central nervous system (CNS), clinically defined by an acute polyfocal neurological syndrome usually with monophasic course. ADEM often occurs after infections, but 5%–10% of cases are preceded by vaccinations. Several cases of ADEM have been described after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, whereas no case has been reported after adenovirus-vectored or mRNA COVID-19 vaccine administration. Here we describe a case of ADEM presenting 2 weeks after receiving the first dose of ChAdOx1 nCoV-19 vaccine. Patient clinical/magnetic resonance imaging (MRI) status spontaneously improved and rapidly resolved with corticosteroids. A 4-month follow-up showed complete recovery and no relapses.

B ackground and aim: C onversion to multiple sclerosis (MS) after optic neuritis and myelitis has been thoroughly studied; however, limited data are available regarding conversion to MS after a clinically isolated syndrome of the brainstem (CISB). The aim of this study was to investigate conversion to MS in patients with C ISB. Methods: Fifty-one patients with C ISB were prospectively studied. C ranial magnetic resonance imaging (MRI), determination of oligoclonal bands (OBs) in the cerebrospinal fluid (C SF) and evoked potentials (EPs) were performed. Based on conversion to MS at follow-up, the sensitivity, specificity, accuracy and positive and negative predictive values of these tests were calculated. Results: C linically definite MS developed in 18 (35%) patients after a mean follow-up of 37 months. Paty’s MRI criteria showed a sensitivity of 89%, a specificity of 52% and an accuracy of 65%; Fazekas’ criteria showed a sensitivity of 89%, a specificity of 48% and an accuracy of 63%; Barkhof’s criteria showed a sensitivity of 78%, a specificity of 61% and an accuracy of 67%. The presence of O Bs in the C SF showed a sensitivity of 100%, a specificity of 42% and an accuracy of 63%. No differences for neurophysiological parameters were found between patients who did and those who did not convert to MS. C onclusion: Fulfilling Paty’s, Fazekas’ or Barkhof’s MRI criteria and the presence of O Bs in the C SF are associated with a higher risk of conversion to MS in patients with C ISB. Determinatio n of O Bs in the C SF has the greatest sensitivity of all tests. Barkhof’s MRI criteria have greater specificity (although less than previously published for mixed cohorts of clinically isolated syndromes) in predicting conversion to MS for C ISB than either Paty’s or Fazekas’ criteria.

The availability of magnetic resonance imaging (MRI) has led to increasing recognition that multiple sclerosis (MS), tumefactive demyelination (TD) and Baló’s concentric sclerosis (BCS) share many overlapping features. Baló-like lesions, which exhibit limited features of BCS, may represent an intermediate between BCS and typical MS demyelination. Lesions labeled as tumefactive are typically larger, but otherwise have much in common with conventional MS lesions, and TD and BCS lesions can also overlap. In this article, we explore the similarities between typical MS, TD and BCS cases, and reflect on the potential insights that intermediate or overlapping phenotypes may contribute towards an understanding of MS immunopathogenesis, and question whether these atypical forms of demyelination should be classified as separate demyelinating diseases, as different lesional manifestations of demyelination of any cause or as part of a spectrum with conventional MS.
