A 13-year-old girl presented with a 5-day history of oscillopsia. On examination, ocular flutter and mild cerebellar signs were found. Brain magnetic resonance imaging (MRI) revealed four periventricular and subcortical non-enhancing lesions. Cerebrospinal fluid (CSF) oligoclonal bands were negative. Neuroblastoma or other malignancies were not found. She responded well to a corticosteroid–intravenous immunoglobulin (IVIG) combination and remained symptom-free for 3 years until presenting again with isolated ocular flutter. Brain MRI at this time remained atypical for classic multiple sclerosis (MS) with a predominance of juxtacortical demyelinating lesions. CSF was positive for oligoclonal bands. Serum myelin oligodendrocyte glycoprotein (MOG) antibodies were present. Ocular flutter can be the presenting feature of MOG antibody–associated pediatric demyelination.

The revision of MEDLINE from 1966 to 2003 did not report any association between multiple sclerosis (MS) and Melkersson—Rosenthal syndrome (MRS). This is a case report of a 51-year-old woman, with history of four recurrent Bell’s palsies. In 1999 she developed a right facial paralysis due to a supranuclear pyramidal lesion with right monoparesis. The family history showed five relatives with recurrent Bell’s paralysis and plicata tongue. Physical examination: right Bell’s paralysis, left supranuclear facial paralysis, furrowed tongue, right hemiparesis with pallor of the optic disks. Brain magnetic resonance imaging (MRI) demonstrated the typical lesions of MS and CSF oligoclonal bands. This is the first observation of a patient with hereditary MRS and MS. The link between both diseases is discussed.

Childhood Mesial Temporal Sclerosis. Ng YT, McGregor AL, Duane DC, Jahnke HK, Bird CR, Wheless JW. J Child Neurol 2006;21(6):512–517. The prevalence and clinical characteristics of mesial temporal sclerosis have not been well studied in children. All brain magnetic resonance imaging (MRI) reports of children less than 14 years of age were reviewed from two tertiary institutions. A 52-month period from one institution and a 37-month period from the other were reviewed. All reports of definite or possible mesial temporal sclerosis were noted. These patients’ MRIs were then reviewed to confirm the MRI diagnostic criteria of mesial temporal sclerosis. The charts of the patients who satisfied these criteria were reviewed in detail. Three thousand one hundred brain MRI reports were reviewed. Twenty-six reports of mesial temporal sclerosis were found. Twenty-four of the 26 films satisfied the criteria of mesial temporal sclerosis by MRI after the films were reviewed. The prevalence among all pediatric brain MRI studies was 0.77%. All patients had presented with seizures, that is, there were no “incidental” findings of mesial temporal sclerosis. Four patients had a history of febrile seizures. Mesial temporal sclerosis is an uncommon finding in children, but when it occurs, it is always associated with epilepsy. Asymptomatic mesial temporal sclerosis or mesial temporal sclerosis not associated with a seizure disorder did not occur in our series. Febrile seizures can occur in association with mesial temporal sclerosis presenting in childhood.

Objective: To compare progressive motor impairment onset attributable to a “critical” central nervous system (CNS) demyelinating lesion in patients with highly restricted versus unlimited magnetic resonance imaging (MRI) lesion burden. Methods: We identified 135 patients with progressive motor impairment for ⩾1 year attributable to a “critical” demyelinating lesion with: MRI burden of 1 lesion (“progressive solitary sclerosis”), 2–5 lesions (“progressive paucisclerosis”), or unrestricted (>5) lesions and “progressive unilateral hemiparesis.” Neuroradiology review of brain and spinal cord MRI documented unequivocally demyelinating lesions. Results: A total of 33 (24.4%) patients had progressive solitary sclerosis; 56 (41.5%) patients had progressive paucisclerosis; and 46 (34.1%) patients had progressive unilateral hemiparesis. Median age at onset of progressive motor impairment was younger in progressive solitary sclerosis (49 years; range 24–73) and progressive paucisclerosis (50 years; range 30–64) than in progressive unilateral hemiparesis (54 years; range 39–77; p = 0.02 and p = 0.003, respectively). Within progressive unilateral hemiparesis, motor-progression onset was similar between those with 4–10, 11–20, or >20 brain lesions (55, 54, 53 years of age, respectively; p = 0.44). Conclusion: Motor-progression age is similar, but paradoxically earlier, in cohorts with highly restricted CNS lesion burden than in those with unrestricted lesion burden with progressive unilateral hemiparetic MS. The “critical” demyelinating lesion rather than total brain MRI lesion burden is the major contributor to motor-progression onset in these cohorts.

ABSTRACT Purpose: To evaluate the contribution of conventional brain magnetic resonance imaging (MRI) for the determination of intracranial aneurysms. Materials and Methods: Brain MRI and computed tomography angiography (CTA) of 45 patients (29 women and 16 men; age range, 32–80 years) with aneurysm were analyzed. A comparison was made between brain MRI and CTA based on size and presence of aneurysm. The comparisons between MRI and CTA were investigated through Bland-Altman graphics, receiver operating characteristic curve, and Kappa statistics. Results: Fifty-seven aneurysms were evaluated. Forty-five percent of 57 aneurysms on CTA were detected on conventional brain MRI. A significant correlation was found between CTA and brain MRI in the diagnosis of aneurysm (P < 0.05). In an analysis of the size measurement, a significant correlation was observed between CTA and brain MRI. Seventy-seven percent of aneurysms <4 mm was not detected and the efficiency of MRI in the detection of aneurysms <4 mm was found to be low. Conclusion: Aneurysms can also be appreciated on conventional brain MRI, and vascular structures should be reviewed carefully while analyzing brain MRI.

A 35-year-old young man displayed Leber’s optic neuropathy (LHON) due to T14484C and multiple sclerosis (MS) phenotype that was dominated by symptoms and signs of spinal cord impairment. Magnetic resonance imaging (MRI) revealed demyelinating lesions extending from D6 to D11 in the spinal cord with gadolinium enhancement, while only three linear demyelinating lesions were seen on brain MRI. In the literature, a major involvement of the spinal cord was already reported in three of four male patients with the 14484 LHON mutation who developed MS, but the reasons of this peculiar association remain unknown, and further research in this area is needed.

Our objective was to describe the types of providers who refer children with autism spectrum disorder (ASD) for brain magnetic resonance imaging (MRI), the referral reason, and MRI results. The most common referral reasons were autism spectrum disorder with seizures (33.7%), autism spectrum disorder alone (26.3%), and autism spectrum disorder with abnormal neurologic examination or preexisting finding (24%). Neurology (62.5%), general pediatric (22.3%), and developmental/behavioral practitioners (8.9%) referred the most patients. The prevalence of definite pathology was highest in children referred for autism spectrum disorder with abnormal neurologic examination/preexisting finding (26.2%, 95% CI: 16.8%-36%), headaches (25.7%, 95% CI: 11.2%-40.2%), or seizures (22%, 95% CI: 14.6%-29.5%), and was lowest in children referred for autism spectrum disorder alone (6.5%, 95% CI: 1.5%-11.6%). We concluded that there is a low prevalence of definite pathology in children with autism spectrum disorder undergoing brain MRI. In children with abnormal neurologic examination or preexisting finding, seizures, or headaches, one may consider performing brain MRI given the higher prevalence of pathology.

Abstract OBJECTIVE Corpora amylacea (CA) normally accumulate within perivascular, subpial, and subependymal astrocytic processes. CA are associated with a number of conditions including normal aging, hippocampal sclerosis associated with temporal lobe epilepsy, multiple sclerosis, Lafora-type progressive myoclonic epilepsy, and adult polyglucosan body disease. Reports of massive localized accumulation of CA in the brain outside of these conditions are rare. CLINICAL PRESENTATION A 49-year-old woman, with a long-standing history of migraine headaches, presented to her primary care provider for increased headache duration. Brain magnetic resonance imaging (MRI) revealed a left parahippocampal lesion, suggestive of low-grade glioma. INTERVENTION Given the MRI suggestive of left parahippocampal glioma, left-sided frontotemporal craniotomy was performed for resection of the lesion. Specimens obtained during the operation revealed focal high-density accumulation of CA with no evidence of neoplasm, ischemia, or hypoxic injury. CONCLUSION This case illustrates the possibility that localized high-density CA accumulation can present as an intrinsic lesion on brain MRI. CA should be included in the differential diagnosis for patients presenting with brain MRI suggestive of nonenhancing space-occupying lesions.

Introduction: In neonatal period, brain magnetic resonance imaging (MRI) is the best neuroimaging to find etiology of seizure. The aim of this study was to evaluate brain MRI findings of neonates with clinical seizure and its effect on diagnostic and therapeutic interventions of newborn. Methods: In a retrospective study, medical records and brain MRI findings of neonates with clinical seizure admitted to Neonatal Intensive Care Unit or Pediatric Ward of Shahid Sadoughi Hospital, Yazd, Iran from September 2018 and before were evaluated. The data were analyzed using SPSS version 16 software , the required indicators and tables were prepared and Fisher exact test and Chi-square test were used to determine the relationship between qualitative variables and independent t-test was used to compare the means in the two groups Results: Twenty-five girls and 38 boys were studied. The cause of seizures was found in 94% and the most common cause of congenital hypoxia was in 22 infants (35%). The most common type of seizure was tonic in 23 infants (36.5%) and the most common type of generalized seizure was in 47 infants (75%). Brain MRI was abnormal in 19 neonates (30%). Based on the MRI results, there was a change in therapeutic interventions (brain surgery) in four infants (6.3%) and in diagnostic interventions (metabolic tests) in 19 infants (30%). Abnormal brain MRI was more frequent in neonates by cesarean section (46%)  than  normal vaginal delivery (19%), (p= 0.01) and also neonates with partial seizure (37.5%) had an abnormal MRI than  generalized seizure (21%), (p= 0.03). Mean of hospitalization days was longer in neonates with abnormal brain MRI (12.32±2.76 days) than neonates with normal MRI (8.57±2.82 days) (P = 0.02). Conclusion: Based on the results of this study, brain MRI might be useful in finding intracranial pathology that causes seizure in neonates by cesarean section to detect birth asphyxia and in newborns with partial seizure.

Background: Chronic lesion activity driven by smoldering inflammation is a pathological hallmark of progressive forms of multiple sclerosis (MS). Objective: To develop a method for automatic detection of slowly expanding/evolving lesions (SELs) on conventional brain magnetic resonance imaging (MRI) and characterize such SELs in primary progressive MS (PPMS) and relapsing MS (RMS) populations. Methods: We defined SELs as contiguous regions of existing T2 lesions showing local expansion assessed by the Jacobian determinant of the deformation between reference and follow-up scans. SEL candidates were assigned a heuristic score based on concentricity and constancy of change in T2- and T1-weighted MRIs. SELs were examined in 1334 RMS patients and 555 PPMS patients. Results: Compared with RMS patients, PPMS patients had higher numbers of SELs ( p = 0.002) and higher T2 volumes of SELs ( p < 0.001). SELs were devoid of gadolinium enhancement. Compared with areas of T2 lesions not classified as SEL, SELs had significantly lower T1 intensity at baseline and larger decrease in T1 intensity over time. Conclusion: We suggest that SELs reflect chronic tissue loss in the absence of ongoing acute inflammation. SELs may represent a conventional brain MRI correlate of chronic active MS lesions and a candidate biomarker for smoldering inflammation in MS.

An 87-year-old man presented with a 2-day history of painful bilateral visual loss. On examination, exophthalmos, lid edema, chemosis, and optic disc edema, on the left side only, were found. Visual acuity was 4/10 OD and no light perception OS. Magnetic resonance imaging (MRI) revealed bilateral optic neuritis and a diffuse and severe infiltration of the intra- and extraconal fat on the left. Laboratory testing was negative except for serum myelin oligodendrocyte glycoprotein (MOG) antibodies. This presentation adds a new variant to the MOG-associated disease spectrum. Testing for MOG antibodies should be considered in patients presenting with diffuse orbital inflammation and optic neuritis.
