RESUMO

BACKGROUND: We aimed to compare the profile of the Wechsler Intelligence Scale for Children Fourth Edition (WISC-IV) between Japanese schoolchildren born very preterm (VP) and with very low birthweight (VLBW) and those with attention deficit hyperactivity disorder (ADHD), and to identify the specific neurocognitive characteristics of VLBW/VP children. METHODS: The VLBW/VP group in the present study included 50 (19 male, 31 female) first- to third-grade elementary school children born between January 2008 and February 2013 at Osaka Medical and Pharmaceutical University Hospital and Saiseikai Suita Hospital with birthweights <1,500 g and <32 gestational weeks. The ADHD group included 18 (13 male, 5 female) first- to third-grade elementary school children who visited Osaka Medical and Pharmaceutical University Hospital between January 2019 and October 2021. Full-scale intelligence quotient scores, four indices, and 12 subtests of the WISC-IV were calculated for all participants and compared between the VLBW/VP and ADHD groups. We assessed whether the patients' clinical history was associated with a low score on the cancellation task in the VLBW/VP group. RESULTS: The WISC-IV profiles showed similar between-group patterns, and the VLBW/VP group had lower cancellation task scores than the ADHD group. CONCLUSIONS: This is the first study to compare WISC-IV profiles between VLBW/VP children and those with ADHD. Further investigation is needed on the association between academic performance and the score of the cancellation task, and the neural mechanism of low performance for cancellation tasks in VLBW/VP children.

RESUMO

BACKGROUND: This study investigated the impact of coronavirus disease 2019 pandemic school closures on the mental health of school students with chronic diseases. METHODS: Questionnaires were distributed to students from 4th-9th grade diagnosed with chronic diseases at Osaka Medical College Hospital and their parents or caregivers. Questionnaires from 286 families were returned by mail after the schools reopened. The students were divided into the "psychosomatic disorder" group (group P, n = 42), the "developmental disorder" group (group D, n = 89), and the "other disease" group (group O, n = 155). Using students' self-reports on the Questionnaire for Triage and Assessment with 30 items, we assessed the proportion of students with a high risk of psychosomatic disorder in three groups. We investigated how the students requiring the support of somatic symptom (SS) felt about school during school closure. Further, using parents' and caregivers' answers, SS scores were calculated before and during school closure and after school reopening. RESULTS: The proportion of students with a high risk of developing psychosomatic disorder increased in all groups. For the students in Group P, the response "I did not want to think about school" indicated an increase in SS scores, and for the students in Group O, "I wanted to get back to school soon" indicated a decrease. Furthermore, especially in Group P students, SS scores decreased transiently during school closure and increased after school reopening. CONCLUSIONS: The impact of school closure on mental health differed depending on students' diagnoses and feelings about school during school closures.

RESUMO

BACKGROUND: Adrenocorticotropic hormone therapy for infantile spasms, including West syndrome, has been previously reported to induce seizures. We present the findings for a school-aged child with epilepsy who developed new focal seizures during adrenocorticotropic hormone therapy. CASE PRESENTATION: The Japanese patient had posttraumatic epilepsy and developed intractable focal seizures at the age of 13 years. Adrenocorticotropic hormone therapy was administered when the patient was 14 years of age. On day 10 of treatment, he developed new focal seizures, which were characterized by left arm contractions followed by movements of touching things with his right hand and writhing and rocking his body left and right and back and forth as automatisms. The focal seizures clustered for 40 minutes and disappeared after suppository administration of 10 mg diazepam. These focal seizures did not reoccur after more than 2 years of follow-up. CONCLUSION: Adrenocorticotropic hormone-induced seizures can occur in children older than previously reported, and can occur in children with intractable seizures other than epileptic spasms.

RESUMO

PURPOSE: Uniparental disomy (UPD) is a rare chromosomal abnormality. We performed whole-exosome sequencing (WES) in cases of early-onset retinal dystrophy and identified two cases likely caused by UPD. Herein, we report these two cases and attempt to clarify the clinical picture of retinal dystrophies caused by UPD. METHODS: WES analysis was performed for two patients and their parents, who were not consanguineous. Functional analysis was performed in cases suspected of congenital disorders of glycosylation (CDG). We obtained clinical case data and reviewed the literature. RESULTS: In case 1, a novel c.57G>C, p.(Trp19Cys) variant in SRD5A3 was detected homozygously. Genetic analysis suggested a maternal UPD on chromosome 4, and functional analysis confirmed CDG. Clinical findings showed early-onset retinal dystrophy, intellectual disability, and epilepsy. In case 2, an Alu insertion (c.4052_4053ins328, p.[Tyr1352Alafs]) in RP1 was detected homozygously. Maternal UPD on chromosome 8 was suspected. The clinical picture was consistent with RP1-related retinitis pigmentosa. Although the clinical features of retinal dystrophy by UPD may vary, most cases present with childhood onset. CONCLUSIONS: There have been limited reports of retinal dystrophy caused by UPD, suggesting that it is rare. Genetic counseling may be encouraged in pediatric cases of retinal dystrophy.

RESUMO

BACKGROUND: The aim of this study was to assess the treatment response to conventional antiepileptic drugs and low-dose adrenocorticotropic hormone therapy for infantile spasms in children with Down syndrome. METHODS: We retrospectively investigated the response and relapse rates, electroencephalography findings, patient characteristics during drug withdrawal, and developmental outcome in 10 children with Down syndrome treated for infantile spasms in our hospital. RESULTS: All patients showed cessation of infantile spasms and achieved electroencephalographic normalization. Spasm relapse occurred in one of 10 patients (10%). Antiepileptic drugs have been withdrawn for seven of 10 patients (70%), none of whom have experienced seizure relapse since drug withdrawal. The median developmental quotient (n = 8) was 20.5, which shows that the developmental outcome was unfavorable. Low-dose adrenocorticotropic hormone therapy achieved a low seizure remission rate of 28.6%. CONCLUSIONS: Elucidation of the optimal treatment for infantile spasms in children with Down syndrome is needed to reduce the duration of infantile spasms and improve the developmental outcome.

RESUMO

OBJECTIVE: To elucidate the clinical characteristics of Japanese pediatric patients with acquired demyelinating diseases (ADS), positive for myelin oligodendrocyte glycoprotein antibody (MOG-IgG), we conducted a nation-wide survey. METHODS: Information about pediatric patients under 18 years old with ADS was solicited with surveys sent to 323 facilities. In an initial survey, we asked whether the center had any patients with ADS, and the MOG-IgG serostatus of the patients. In a follow-up survey, we requested more precise information on patients with ADS. RESULTS: Initial survey: 263 replies providing information on 175 patients were received. MOG-IgG were examined in 78 patients and 54 of those (69%) were positive for MOG-IgG. Follow-up survey: The characteristic involvement was optic neuritis, with visual disturbance and optic pain as characteristic symptoms. The relapse rate was 44% in patients positive for MOG-IgG, which was higher than that in seronegative patients (38%). For acute phase treatments, corticosteroid (CS), plasma exchange, and intravenous immunoglobulin (IVIG) were useful. To prevent relapse, CS, intermittent IVIG, immunosuppressants, and monoclonal antibodies were useful, but the efficacies of disease modifying drugs were uncertain. Sequelae such as visual disturbance, cognitive impairment, motor dysfunction, and epilepsy were observed in 11% of patients with MOG-IgG. CONCLUSIONS: MOG antibody-associated diseases were found to be common among pediatric ADS patients. Since a variety of sequelae were observed in these patients, it is important to identify the appropriate treatment to ensure the best outcome. The presence of the MOG autoantibody should be taken into consideration as part of the diagnostic criteria for pediatric ADS.

RESUMO

BACKGROUND: Brain abscesses are relatively rare, but they are a potentially life-threatening condition. Predictive factors for poor outcome are a young age and the presence of multiple abscesses. We report a case of a 15-month-old girl with cyanotic congenital heart disease who developed multiple brain abscesses caused by Streptococcus intermedius. The patient was treated with a combination of surgical aspiration and antimicrobial therapy without apparent neurological sequelae. To the best of our knowledge, this is the youngest such patient to have been reported in the literature. We explore the possible causes of her good outcome. CASE PRESENTATION: At the age of 15 months, the Japanese patient initially was presented to our hospital with transient eye deviation to the left and vomiting. In a blood examination, her white blood cell count (12,720 per mm3 with a left shift) and C-reactive protein level (1.23 mg/ml) were slightly elevated. Magnetic resonance imaging of the brain showed three mass lesions. These were 1.5-cm, 1.9-cm, and 1.2-cm rim-enhancing lesions with extensive surrounding edema. Brain abscesses were diagnosed, and vancomycin (50 mg every 12 hours) and meropenem (40 mg every 8 hours) were started empirically. However, because each brain abscess was enlarged at 8 days after admission, surgical aspiration was performed at 10 days after admission, and cultures of the aspirated pus grew S. intermedius. Penicillin G (0.7 million units every 4 hours) and ceftriaxone (280 mg every 12 hours), to which this isolate is susceptible, were then administered, and the brain abscesses reduced in size. After 1 month of ceftriaxone and 3 months of penicillin G treatment, all of the brain abscesses disappeared. Apparent neurological sequelae were not observed at 6 months after onset. CONCLUSIONS: A good outcome can be obtained if multiple brain abscesses develop in infancy or early childhood in cases without unconsciousness at admission, meningitis, or sepsis. Appropriate antimicrobial therapy should be started immediately after diagnosis, with surgical aspiration performed to identify the causative pathogen and avoid intraventricular rupture of the brain abscesses.

RESUMO

SIGNIFICANCE: Our study revealed that the validity of a new Japanese visual-perceptual test was acceptable. Visual-perceptual abilities are important to activities of daily living; thus, accurate assessment of visual perception is especially important for children with neurodevelopmental disorders and particularly so for those with learning problems. PURPOSE: Visual perception refers to the process by which one receives visual information through sensory impulses and then translates those impulses into meaning based on a previously developed view of the environment. A problem in Japan is the paucity of visual perception tests that use normative data from children who are native Japanese. The Wide-range Assessment of Vision-related Essential Skills (WAVES), which measures visual perception and eye-hand coordination skills and is based on Japanese normative data, was recently published in Japan. The validity of this test has not been comprehensively established. METHODS: To investigate the validity of the WAVES, we used the Pearson correlation coefficient to calculate the degrees of association among WAVES scaled and index scores compared with Developmental Test of Visual Perception, Third Edition, scores from 108 elementary school children with symptoms of learning problems. Participants were recruited at Osaka Medical College Learning Disability Center and Sakai Seikeikai Learning Disability Center. RESULTS: The concurrent validity of the WAVES was supported by moderate correlation (r = 0.67, P < .01) between the total scores for visual perception and eye-hand coordination index from the WAVES and general visual perception index from the Developmental Test of Visual Perception, Third Edition, even though a correlation analysis of subtests found differences between the two tests. CONCLUSIONS: Our results showed that the indices from the two tests measured nearly the same underlying visual-perceptual constructs and indicated that the WAVES had acceptable levels of concurrent validity.

RESUMO

OBJECTIVE: Febrile seizures (FSs) typically occur in infants and children between 6 and 60 months of age. Rarely, FS can occur in late childhood (late FS [LFS]; >5 years of age); however, the clinical features of LFS remain unclear. We aimed to clarify the clinical features of LFS. METHODS: We retrospectively analyzed data from patients with LFS who visited Hirakata City Hospital between January 2004 and December 2014. We defined LFS as a seizure accompanied by fever (temperature ≥38 °C) occurring after 5 years of age, without a central nervous system infection. RESULTS: A total of 505 patients (349 boys, 156 girls: 5-14 years old) were included. A history of FS before 60 months of age was observed in 319 of 460 patients (69.3%) with sufficient information about previous FS history among the 505 patients enrolled. LFS was more likely to occur in males (69.1%). Seizure duration was ≤15 min in 87.4% of cases. A family history of FS in first-degree relatives was observed in 103/327 cases (31.5%). Among LFS cases, 45% occurred at 5 years of age, and 92.1% experienced only one seizure after 5 years of age. The number of seizure episodes gradually lessened with age, decreasing drastically to 5.6% of cases older than 9 years. CONCLUSIONS: Our findings suggest that sex differences, seizure duration, and family history were similar for LFS and FS. Over 90% patients with LFS experienced no recurrence after 5 years of age. Further study is needed to verify the recurrence rate of LFS.

RESUMO

The leukodystrophies cause severe neurodevelopmental defects from birth and follow an incurable and progressive course that often leads to premature death. It has recently been reported that abnormalities in aminoacyl t-RNA synthetase (ARS) genes are linked to various unique leukodystrophies and leukoencephalopathies. Aminoacyl t-RNA synthetase proteins are fundamentally known as the first enzymes of translation, catalysing the conjugation of amino acids to cognate tRNAs for protein synthesis. It is known that certain aminoacyl t-RNA synthetase have multiple non-canonical roles in both transcription and translation, and their disruption results in varied and complicated phenotypes. We clinically and genetically studied seven patients (six male and one female; aged 2 to 12 years) from five unrelated families who all showed the same phenotypes of severe developmental delay or arrest (7/7), hypotonia (6/7), deafness (7/7) and inability to speak (6/7). The subjects further developed intractable epilepsy (7/7) and nystagmus (6/6) with increasing age. They demonstrated characteristic laboratory data, including increased lactate and/or pyruvate levels (7/7), and imaging findings (7/7), including calcification and abnormal signals in the white matter and pathological involvement (2/2) of the corticospinal tracts. Through whole-exome sequencing, we discovered genetic abnormalities in lysyl-tRNA synthetase (KARS). All patients harboured the variant [c.1786C>T, p.Leu596Phe] KARS isoform 1 ([c.1702C>T, p.Leu568Phe] of KARS isoform 2) either in the homozygous state or compound heterozygous state with the following KARS variants, [c.879+1G>A; c.1786C>T, p.Glu252_Glu293del; p.Leu596Phe] ([c.795+1G>A; c.1702C>T, p.Glu224_Glu255del; p.Leu568Phe]) and [c.650G>A; c.1786C>T, p.Gly217Asp; p.Leu596Phe] ([c.566G>A; c.1702C>T, p.Gly189Asp; p.Leu568Phe]). Moreover, similarly disrupted lysyl-tRNA synthetase (LysRS) proteins showed reduced enzymatic activities and abnormal CNSs in Xenopus embryos. Additionally, LysRS acts as a non-canonical inducer of the immune response and has transcriptional activity. We speculated that the complex functions of the abnormal LysRS proteins led to the severe phenotypes in our patients. These KARS pathological variants are novel, including the variant [c.1786C>T; p.Leu596Phe] (c.1702C>T; p.Leu568Phe) shared by all patients in the homozygous or compound-heterozygous state. This common position may play an important role in the development of severe progressive leukodystrophy. Further research is warranted to further elucidate this relationship and to investigate how specific mutated LysRS proteins function to understand the broad spectrum of KARS-related diseases.

RESUMO

PURPOSE: To report a case of fundus oculi albinoticus diagnosed as Angelman syndrome (AS) via genetic testing. CASE REPORT: This study reports on a 4-year-old boy. Since he had been having respiratory disturbance since birth, he underwent a complete physical examination to investigate the cause. The results indicated that he had various brain congenital abnormalities, such as a thin corpus callosum, as well as hydronephrosis, an atrial septal defect, and skin similar to patients with fundus oculi albinoticus. Examination revealed bilateral fundus oculi albinoticus, mild iridic hypopigmentation, optic atrophy, and poor visual tracking. Genetic testing revealed a deletion in the Prader-Willi syndrome/AS region on chromosome 15, and together with the results of methylation analysis, his condition was diagnosed as AS. Follow-up examinations revealed no change in the fundus oculi albinoticus and optic atrophy, nor did they indicate poor visual tracking. CONCLUSIONS: When fundus oculi albinoticus and optic atrophy are observed in patients with multiple malformations, AS should be considered as a differential diagnosis.

RESUMO

BACKGROUND: Immunomodulatory therapy has shown some therapeutic benefits in patients with anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis. In this report, we describe the use of adrenocorticotropic hormone (ACTH) immunotherapy with good outcome in a patient with anti-NMDAR encephalitis. SUBJECT AND METHODS: A 4-year-old girl developed convulsions in her right arm and leg without impaired consciousness. These convulsions occurred frequently in clusters of 10-20 events of 10-20 s duration. She was admitted to our hospital on the 6th day following her initial series of convulsions. Flaccid paralysis of the right hand and leg was also found. Interictal electroencephalography showed high-amplitude slow waves. No abnormal findings were shown on MRI. 99mTc-ECD brain SPECT on the 14th day showed hyperperfusion in the left hemisphere, including the left basal ganglia. The convulsions ceased following the oral administration of valproic acid on the 10th day; however, paralysis associated with choreic dyskinesia of the right arm and leg remained. ACTH immunotherapy was then performed on the 15th day. We identified the presence of N-methyl-D-aspartate receptor antibody in CSF samples taken on the 6th day. After ACTH therapy, the patient fully recovered from the paralysis associated with choreic dyskinesia of the right arm and leg. She has not had a relapse and has not required medication for over a year. CONCLUSION: ACTH immunotherapy may be a useful treatment option for patients with anti-NMDAR encephalitis, although further evaluation is required.

RESUMO

MED13L haploinsufficiency syndrome is a clinical condition manifesting intellectual disability and developmental delay in association with various complications including congenital heart defects and dysmorphic features. Most of the previously reported patients showed de novo loss-of-function mutations in MED13L. Additional three patients with MED13L haploinsufficiency syndrome were identified here in association with rare complications. One patient had a de novo deletion (c.257delT) and T2-weighted high intensity in the occipital white matter on magnetic resonance imaging. Two siblings exhibited an intragenic deletion involving exons 3-14, which led to an in-frame deletion in MED13L. The deletion was inherited from their carrier mother who possessed low frequency mosaicism. The older sister of the siblings showed craniosynostosis; this condition has never been reported in patients with MED13L haploinsufficiency syndrome. Dysmorphic features were observed in these patients; however, most of the findings were nonspecific. Further information would be necessary to understand this clinical condition better.

RESUMO

PURPOSE: We performed ophthalmic examinations, including optical coherence tomography (OCT), on a case diagnosed with hydranencephaly. CASE REPORT: This case involved a female infant born at the gestational age of 35 weeks and 4 days, with the birth weight of 2,152 g, who was one of monochorionic diamniotic twins, and the identical twin died in utero at the gestational age of 24 weeks. After that, examination by fetal echo indicated that she had microcephaly and ventriculomegaly. Postnatal magnetic resonance imaging (MRI) of her head indicated microcephaly and significant enlargement of the lateral ventricle on both sides, with no obvious signs of elevated intracranial pressure. The brain parenchyma of both sides of the frontal lobe, parietal lobe, and occipital lobe had marked thinning, yet that of the temporal lobe, basal ganglia, thalamus, brain stem, and cerebellum had been maintained. Moreover, no obvious hematoma or neoplastic lesions were observed. Ophthalmic examinations indicated that both of her eyes had slight light reflex, attributed to optic nerve atrophy. Examination by use of a hand-held OCT system indicated a layered structure of the retina and thinning of the ganglion cell layer. Flicker electroretinogram (ERG) examination by use of a hand-held ERG system indicated an almost normal wave. However, no clear visual reaction was observed when she was 10 months old. CONCLUSION: Our findings in this case of hydranencephaly revealed that even though the outer layer functions of the patient's retina were maintained, extensive damage to her cerebral cortex resulted in poor visual function.

RESUMO

We report a 13-month-old girl who developed acute encephalopathy with biphasic seizures and late reduced diffusion (AESD) with transient reduced diffusion in the hippocampus and anterior commissure on diffusion-weighted imaging (DWI), which was performed on the first day after febrile status epilepticus (FSE) as the initial neurological symptom of AESD. DWI just after late seizures showed high signal intensity lesions in both left hippocampus and anterior commissure, and left extratemporal and occipital subcortical white matter. HHV-6 DNA was positive in both blood and cerebrospinal fluid samples. DWI at two months after onset showed atrophy in the left mesial temporal lobe and extratemporal and occipital lobe without the signal abnormalities. Although it has been reported that magnetic resonance images tend to show no acute abnormality during the first two days in typical AESD, transient reduced diffusion could be found on the DWI performed on the first day of AESD.

RESUMO

The mechanism of post-vaccination acute disseminated encephalomyelitis (ADEM) has been hypothesized as resulting from vaccination-injected antigens cross-reacting with myelin components, however, a precise etiology has been uncertain. In this report, we describe the case of a 6-year-old Japanese boy who had multiphasic disseminated encephalomyelitis (MDEM), and was positive for both anti-myelin oligodendrocyte glycoprotein (MOG) antibodies and Chlamydophila pneumoniae antibodies. After vaccinations that were the second one for measles and rubella, and the booster immunization for Japanese encephalitis, the patient presented with fever, headache, vomiting, and a change in personality. He was treated with a high-dose of intravenous methylprednisolone in the diagnosis of ADEM. However, these symptoms recurred with different magnetic resonance imaging lesion, and he was diagnosed as MDEM. Retrospective testing for pathogens revealed C. pneumoniae IgM and IgG antibodies, and it was considered that he was infected with C. pneumoniae subclinically. The patient's serum indicated a positive response for the anti-MOG antibody from the onset of the ADEM diagnosis and in all recurrent episodes. Chlamydia species infection has been known to play a role in demyelinating diseases. It is also known that the anti-MOG antibody may be present but not exhibit its pathogenesis in the absence of a cell-mediated inflammatory response; however, the precise mechanism of action of the anti-MOG antibodies is not yet determined. We propose the possibility that post-vaccination demyelinating disease may result from the synergistic effects of a preceding anti-MOG antibody, possibly produced in response to a subclinical Chlamydia species infection.

RESUMO

BACKGROUND: The aim of this study was to assess the rate of response to long-term low-dose levetiracetam (LEV) treatment and the clinical factors associated with response. METHODS: The response to low-dose LEV of 43 patients with epilepsy (22 male, 21 female; age range, 5-39 years; median age, 13 years) was retrospectively assessed. Patients aged <15 years received <20 mg/kg/day LEV, whereas those aged ≥15 years received <1000 mg/day LEV. Clinical features were compared between responders to low-dose LEV, responders to the recommended dose, and non-responders. RESULTS: Of the 43 patients who received low-dose LEV, 13 (30%) showed improvement, defined as seizure cessation or >75% seizure reduction over 6 months for patients with monthly, weekly, and daily seizures; and over 1 year for patients with yearly seizures. Efficacy was maintained for >1 year in 10 (77%) of the 13 patients. Long-term response to low-dose LEV was significantly associated with older age at onset and fewer previous treatments with ineffective anti-epileptic drugs. All patients showing long-term response to low-dose LEV developed only focal seizures. CONCLUSIONS: Titration of LEV starting from a low dose may be effective in selected patients. Once patients respond to low-dose treatment, maintenance of the effective dosage may prolong response.

RESUMO

Objective: Patients with childhood-onset epilepsy often need continued epilepsy treatment into adulthood. We investigated parents' opinions of the changes in their children's epilepsy treatment during the transition from childhood to adulthood using questionnaires and formulated agendas to build the appropriate medical treatment system for epilepsy. Methods: We distributed questionnaires to parents of patients with epilepsy who were 12 to 18 years old. Results: We distributed 176 questionnaires, and analyzed 79 (45%) questionnaires. Most parents (59%) wanted their child to continue treatment for epilepsy in the pediatrics department because of confidence in the current treatment environment. Most parents (73%) were anxious about their child not being treated in the pediatrics department during future epilepsy medical treatments because of concerns about whether a proper handover from the pediatrics department to other departments is possible. No parent was recommended the departmental transition by the primary pediatrician to other courses for future epilepsy treatment, while 19% of par-ents had a sense of incongruity regarding epilepsy treatment at the current pediatrics department. Parents who were anxious about future epilepsy treatments had significantly fewer general-school students than parents without anxiety. In addition, their children had more seizures than children of parents who were not anxious. Furthermore, they wanted their child to continue treatment for epilepsy in the pediatrics department more than the parents without anxiety. Conclusions: Approximately 70% of the parents were anxious about obtaining future epilepsy treatment in clinical departments other than the pediatrics department. To build a satisfactory medical treatment system for patients with epilepsy having different backgrounds and requiring continued treatment in adulthood, it is important to create a cooperating network consisting of pediatricians, neurologists, neurosurgeons, psychiatrists, and epileptologists.

RESUMO

Multiple sclerosis (MS) is a syndrome characterized by complex neurological symptoms resulting from demyelinating lesions in the central nervous system. We report a child with a relapse of MS whose only presenting symptom was severe abdominal pain. Dysfunctional intestinal mobility was assessed by abdominal computed tomography. Findings resembled paralytic ileus resulting from peritonitis. However, the patient demonstrated no other symptoms of peritonitis. A T2-weighted magnetic resonance image revealed a new demyelinating lesion localized to thoracic segments T4-T12. The lesion presumably affected autonomic efferents involved in intestinal mobility. Treatment with a pulse of methylprednisolone reduced both abdominal pain and lesion size. To our knowledge, this is the first reported case of a pediatric MS patient with a demyelinating lesion associated with an autonomic symptom of altered intestinal mobility in the absence of neurological symptoms. This atypical presentation of MS highlights the need for physicians' vigilance when treating this patient population.
