A 49-year-old woman sought care for a 9-month history of gait difficulty. She was dragging her right foot when walking and could not walk more than 3 blocks because of right leg weakness. Physical examination showed right-sided weakness of hip flexion and foot dorsiflexion and symmetrical hyperreflexia at the knees and ankles. Magnetic resonance imaging of the brain showed multiple foci of T2 hyperintensity throughout the white matter in both cerebral and cerebellar hemispheres, predominantly in a periventricular distribution. Several small enhancing lesions and mild generalized cerebral volume loss were seen. The appearance and distribution were consistent with a demyelinating process such as multiple sclerosis. Magnetic resonance imaging of the cervical and thoracic spine showed multiple small T2 hyperintensities, including 1 enhancing lesion in the cervical spinal cord. Oligoclonal bands were positive, with 11 unique bands in the cerebrospinal fluid. The concentration of cerebrospinal fluid kappa free light chains was increased, at 0.314 mg/dL. The patient was diagnosed with relapsing-remitting multiple sclerosis. A 5-day course of intravenous corticosteroids was started, after which she noted clinical improvement. At her last follow-up 2 years after initial evaluation, the patient has been stable with no new clinical multiple sclerosis episodes and stable magnetic resonance imaging disease burden with no new lesions. The diagnosis of multiple sclerosis incorporates clinical, imaging, and laboratory evidence. The 2017 revised McDonald criteria state that a finding of cerebrospinal fluid -specific oligoclonal bands can replace the criterion for dissemination in time to make a diagnosis of definitive multiple sclerosis. The standard test for oligoclonal bands is performed using isoelectric focusing electrophoresis and takes more than 3 hours to complete. The case patient had 11 unique cerebrospinal fluid bands. The number of bands is not correlated with disease severity or prognosis.

Background Steps towards the development of diagnostic criteria are needed for children with the radiologically isolated syndrome to identify children at risk of clinical demyelination. Objectives To evaluate the 2005 and 2016 MAGNIMS magnetic resonance imaging criteria for dissemination in space for multiple sclerosis, both alone and with oligoclonal bands in cerebrospinal fluid added, as predictors of a first clinical event consistent with central nervous system demyelination in children with radiologically isolated syndrome. Methods We analysed an international historical cohort of 61 children with radiologically isolated syndrome (≤18 years), defined using the 2010 magnetic resonance imaging dissemination in space criteria (Ped-RIS) who were followed longitudinally (mean 4.2 ± 4.7 years). All index scans also met the 2017 magnetic resonance imaging dissemination in space criteria. Results Diagnostic indices (95% confidence intervals) for the 2005 dissemination in space criteria, with and without oligoclonal bands, were: sensitivity 66.7% (38.4–88.2%) versus 72.7% (49.8–89.3%); specificity 83.3% (58.6–96.4%) versus 53.9% (37.2–69.9%). For the 2016 MAGNIMS dissemination in space criteria diagnostic indices were: sensitivity 76.5% (50.1–93.2%) versus 100% (84.6–100%); specificity 72.7% (49.8–89.3%) versus 25.6% (13.0–42.1%). Conclusions Oligoclonal bands increased the specificity of magnetic resonance imaging criteria in children with Ped-RIS. Clinicians should consider testing cerebrospinal fluid to improve diagnostic certainty. There is rationale to include cerebrospinal fluid analysis for biomarkers including oligoclonal bands in planned prospective studies to develop optimal diagnostic criteria for radiologically isolated syndrome in children.

In clinically isolated syndrome (CIS), the detection of oligoclonal bands (OCBs) in cerebrospinal fluid (CSF) is critical for space dissemination validation when magnetic resonance imaging (MRI) diagnostic criteria are not fulfilled. However, lumbar puncture for CSF collection is considered relatively invasive. Previous studies have demonstrated applicability of OCB detection in tears to the diagnosis of multiple sclerosis (MS). The objective of the present study was to assess concordance between OCB detection in tears and in CSF. We have prospectively included patients with CIS and compared results of CSF and tear OCB detection by isoelectric focusing (IEF). Tears were collected using a Schirmer strip. We included 82 patients. For 69 of them, samples were analysable. OCBs were detected in CSF for 63.8% and in tears for 42% of patients. All patients with tear OCBs had CSF OCBs. We suggest that tear OCB detection may replace CSF OCB detection as a diagnostic tool in patients with CIS. This would circumvent the practice of invasive lumbar punctures currently used in MS diagnosis.

A 58-year-old, right-handed man with a medical history of nephrolithiasis, essential hypertension, and type 2 diabetes sought care for a 6-year history of gait impairment. Initially, he noted subtle left foot and ankle weakness with associated falls that progressed over time. Two to 3 years later he again noted progressive left leg weakness and new arm weakness. Subsequently, progressive pain developed on the soles of his feet in addition to edema with erythematous discoloration around the left ankle and foot. On neurologic examination, he was found to have mild upper motor neuron pattern weakness in the left arm and leg, most pronounced in the left hand finger extensor and left hip flexion and abduction. Left patellar reflex was brisk, and there was an extensor Babinski sign on the left. There was mild reduction in pinprick sensation in both feet. His gait was spastic with left leg circumduction. Magnetic resonance imaging of the brain showed left-sided predominant periventricular and subcortical T2 fluid-attenuated inversion recovery hyperintensities. Magnetic resonance imaging of the cervical and thoracic spinal cord showed intramedullary cord T2 signal hyperintensities, eccentrically located on the left at C3, C5, C6, on the right at C7 to T1, and centrally at T4/T5 and T8/T9. A diagnosis of primary progressive multiple sclerosis was made. The patient met the 2017 McDonald criteria for primary progressive multiple sclerosis. After the diagnosis was confirmed and comprehensive education about the disease and the role of disease-modifying therapy was discussed with the patient, he was started on ocrelizumab. Gabapentin was started for management of painful foot paresthesias. Vitamin D3 supplementation was started. Physical therapy was also initiated. Multiple sclerosis is a chronic immune-mediated demyelinating disease of the central nervous system and is the leading cause of disability in the young population. Approximately 1 million people in the United States currently have multiple sclerosis.

A 59-year-old White man with a history of excised basal and squamous cell skin cancers was evaluated for gait difficulties. He had erectile dysfunction but no bowel or bladder dysfunction. He also reported fatigue. He began using a cane for ambulation 2 weeks before evaluation at our facility. His medications included vitamin D and sildenafil. He was a lifelong nonsmoker and had no family history of multiple sclerosis. Neurologic examination at the time of our evaluation 3 years after onset was notable for a positive Hoffman sign on the right and mild weakness of the right triceps but preserved strength elsewhere. He had a spastic gait with moderate spasticity in both lower extremities, hyperreflexic patellar and ankle jerks bilaterally, and bilateral positive Babinski sign. The remainder of the examination was essentially normal. Magnetic resonance imaging of the brain showed a single lesion at the cervicomedullary junction and medullary pyramids, more prominent on the right. There was also some accompanying atrophy that was also visible on cervical spine magnetic resonance imaging. Results of cerebrospinal fluid analysis showed a normal white blood cell count, increased protein concentration (108 mg/dL), and positive oligoclonal bands. The progressive nature of his symptoms, spinal fluid results, and lesion appearance were all consistent with a diagnosis of progressive solitary sclerosis. At the time this patient was seen, no immunomodulatory medications for progressive solitary sclerosis were approved, so no immunomodulatory medication was tried. Ongoing symptomatic management was recommended. Progressive solitary sclerosis is a rare variant of multiple sclerosis in which patients have a single central nervous system demyelinating lesion and development of motor progression attributable to that lesion. Patients can initially have a clinical episode followed by progression or can have a progressive course without an initial relapse.

Because no laboratory test or imaging study is both highly sensitive and highly specific for multiple sclerosis, some uncertainty often accompanies the diagnosis. Various guidelines have been developed to assist the clinician, including the much-modified and commonly used McDonald criteria. Typical features of the history, the physical examination, and magnetic resonance imaging findings usually allow for a secure diagnosis. However, limitations inherent in any testing modality still pose challenges. This is especially true for diagnosis of primary progressive multiple sclerosis because the sensitivity and specificity of the evaluations are lower.

In patients who present with a clinically isolated syndrome (CIS), whose features are suggestive of multiple sclerosis (MS), fulfilling McDonald 2010 magnetic resonance imaging (MRI) criteria for dissemination in space (DIS) and dissemination in time (DIT) enables a diagnosis of MS. While ⩾1 periventricular lesion is included in the 2010 DIS criteria, earlier McDonald criteria required ⩾3 periventricular lesions to confirm DIS and recent Magnetic Resonance Imaging in Multiple Sclerosis (MAGNIMS)-recommended DIS criteria also require ⩾3 lesions. We investigated the effect of varying the required number of periventricular lesions and found that the best combination of specificity and sensitivity for clinically definite MS was seen for ⩾1 periventricular lesion using both the McDonald 2010 and MAGNIMS 2016 criteria.
