It is commonly associated with penetrating spinal trauma. Nontraumatic etiologies, particularly tumors at the craniocervical junction, are rare and may have atypical presentations leading to delayed diagnosis. We report an unusual case of atypical Brown–Sequard syndrome in an adolescent caused by a rare mesenchymal tumor at the foramen magnum.</p><p>This 14-year-old previously healthy boy presented with a 1-week history of cold sensation loss in the right hand and progressive weakness in the left hand. His neurological examination revealed left hemiparesis, hyperreflexia with Babinski sign, and diminished pain and temperature sensation on the right. His cranial nerve examination was normal without evidence of Horner syndrome. Vibration sensation was mildly reduced bilaterally, suggesting partial involvement of the dorsal column–medial lemniscus pathway. Overall, the neurological examination was consistent with a hemicord syndrome localizing to the upper cervical cord. Contrast-enhanced computed tomography of the head and cervical spine demonstrated a calcified, heterogeneously enhancing craniocervical junction mass with cord compression (Figure 1A–C). Magnetic resonance imaging revealed a lobulated, homogeneously enhancing tumor centered at the anterior foramen magnum with mass effect on the medulla, craniocervical junction, and proximal cervical cord (Figure 1D–H). Neuroimaging features were most consistent with chordoma, meningioma, or sarcoma.</p><p>The patient underwent gross total resection without complications. Three days postoperatively, he showed significant improvement in strength and temperature sensation. Histopathology demonstrated a biphasic tumor composed of sheets of malignant small round blue cells intermixed with nodules of hyaline cartilage (Figure 2). RNA sequencing identified a HEY1::NCOA2 fusion, confirming a diagnosis of mesenchymal chondrosarcoma (MCS). Postoperative treatment with chemotherapy (vincristine, doxorubicin, cyclophosphamide, ifosfamide, etoposide) and focal proton radiation resulted in complete response without evidence of tumor recurrence more than 1 year post diagnosis.</p><p>Primary spinal cord tumors are uncommon in children and typically present with a slow, indolent course.

A sibling has postural orthostatic tachycardia syndrome (POTS). This condition is rarely reported and likely underrecognized.</p><p>This previously healthy 12-year-old boy presented to the dysautonomia clinic for evaluation of a 4-month history of syncope precipitated by stretching. These events consisted of an initial sensation of his back “feeling funny” that induced stretching. When performed in any position, this resulted in what he described as “tunnel vision” and syncope lasting up to 30 s, with occasional brief, subtle jerking of his extremities. He described a brief prodrome of diminished hearing and a \"heavy\" feeling in his head. Following the episode, he experienced confusion but quickly returned to baseline. Temperature, large meals, and poor hydration did not affect frequency, and there were no other associated symptoms. His past history includes anxiety and attention-deficit/hyperactivity disorder, treated with sertraline and dexmethylphenidate. His family history was contributory only for a sister with POTS.</p><p>His neurological examination was normal. When transitioning from lying to sitting to standing, his heart rate increased by 25 beats per minute, below the criteria for a POTS diagnosis.</p><p>An earlier inpatient electroencephalogram had a normal background rhythm without epileptiform activity, including during an episode of dizziness and left arm shaking.

By utilizing an antisense oligonucleotide to upregulate Nav1.1 expression from the wild-type <i>SCN1A</i> allele, the therapeutic paradigm is finally shifting from symptomatic seizure suppression toward addressing the root genetic etiology. While the reported reductions in convulsive seizures are highly encouraging, evaluating zorevunersen exclusively as an adjunctive therapy alongside standard, non-sodium-channel-blocking antiseizure medications forecloses the most consequential test of genuine disease modification [<span>1</span>].</p><p>Dravet syndrome is fundamentally driven by <i>SCN1A</i> haploinsufficiency, which selectively impairs Nav1.1 channels in GABAergic inhibitory interneurons. Consequently, sodium channel blockers (SCBs) are strictly contraindicated; they further diminish interneuron excitability, precipitate severe seizure exacerbations, and independently impair cognitive outcomes [<span>2, 3</span>]. However, if sustained target engagement by zorevunersen genuinely restores Nav1.1 to physiological levels, the specific molecular deficit that renders SCBs harmful should, in principle, be reversed [<span>1</span>].</p><p>Demonstrating that a targeted therapy safely restores tolerance to SCBs would represent the ultimate, irrefutable proof of true disease modification. Unfortunately, the clinical development program for zorevunersen—including the forthcoming phase 3 EMPEROR trial (NCT06872125)—perpetuates the strict exclusion of patients receiving maintenance SCBs. By avoiding this specific pharmacological challenge, the field risks embedding a critical knowledge gap permanently into clinical practice, leaving it ambiguous whether the underlying neuropharmacological phenotype has been truly normalized or if seizures are merely being suppressed.</p><p>While intentionally administering contraindicated drugs poses obvious ethical challenges in trials, real-world clinical practice offers unique opportunities for insight.

Paul Rosman, MD, CM, legendary child neurologist and consummate leader devoted to the neurological care of children, died in Boston, MA, on March 18, 2026, at age 91. Dr. Rosman founded and led the child neurology division at Boston University's Boston City Hospital and carried the title of Professor Emeritus of Pediatrics and Neurology at the Boston University Chobanian & Avedisian School of Medicine at the time of his death.</p><p>Dr. Rosman helped shape the modern field of child neurology and influenced generations of child neurologists worldwide. For more than six decades, he was admired widely for his clinical insight, intellectual rigor, and deep compassion for his patients and their families.</p><p>Born in Ottawa, Canada, in 1934, Dr. Rosman graduated <i>magna cum laude</i> from McGill University, where he earned both a BSc and his medical degree. He then completed training in New York and returned to McGill for further residency. In 1963, he moved to Boston, where he spent the remainder of his career and played a key role in advancing clinical care, education, and research in pediatric neurology. In 1969, he became the first chief of child neurology at Boston City Hospital, where he remained for 17 years [<span>1</span>]. He then became chief of the division of pediatric neurology at the Floating Hospital for Children at Tufts–New England Medical Center, where he co-founded and directed the Center for Children with Special Needs, advancing multidisciplinary, family-centered care for children with complex neurodevelopmental conditions. Upon his retirement from the Floating, more than 70 of his former trainees, colleagues, and friends from at least 15 states and five foreign countries gathered at a festschrift to celebrate his lifetime of patient care, teaching, mentoring, and research. He remained clinically active at Boston Medical Center for many more years, returning in 2004, when he generously helped his colleague, friend, and newly appointed chief of child neurology, Karl Kuban, rebuild a board-approved child neurology residency program at Boston Medical Center/Boston University.</p><p>Internationally recognized for his scholarship and leadership, Dr. Rosman authored more than 200 articles and book chapters, received more than 30 research grants, and made foundational contributions to the understanding of febrile seizures and neurodevelopmental disorders. He co-wrote a classic text, <i>Pediatrics, Neurology, and Psychiatry—Common Ground</i>, which melded his interest in the overlap between neurology and behavior.

The contributing factors for leukodystrophy mortality are incompletely understood. Our objectives were to characterize inpatient deaths of pediatric leukodystrophies, including demographics and risk factors.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>This retrospective cohort analysis utilized the national Pediatric Health Information System (PHIS) database. Patients under age 19 years with an (ICD-10) diagnosis of leukodystrophy and an inpatient encounter at a PHIS hospital between 2016 and 2024 were included. Analysis included descriptive and multivariate statistics.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>In all, 613 patients with 15 different leukodystrophies were identified; 32 patients died (5.2%). The most common diagnoses of patients who died were Krabbe disease (KD) (31%), adrenoleukodystrophy (ALD) (28%), metachromatic leukodystrophy (MLD) (28%), and vanishing white matter disease (VWM) (6%). Volume of leukodystrophy admissions at individual hospitals was inversely correlated with mortality. Small numbers limited statistical significance, but mortality rates were higher in females than males (8.3% vs<i>.</i> 3.8%); and Black, Asian, and multiracial patients were more likely to die than White patients, 8.4%, 7.7%, and 8.7%, versus 4.1%.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>In this large national administrative database study, we characterized and helped define risks for inpatient mortality of pediatric leukodystrophies. Inpatient mortality was correlated with clinical risk factors, and further, although small numbers precluded statistical significance, mortality disparities by sex and race were identified. The reasons for these differences are not known and warrant further study. Our findings identify directions for new research and underscore the potential impact of specialized institutional experience.</p>\u0000 </section>\u0000 </div>","PeriodicalId":72232,"journal":{"name":"Annals of the Child Neurology Society","volume":"4 3","pages":"207-218"},"PeriodicalIF":0.0,"publicationDate":"2026-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cns3.70086","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148974994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
