Nerve root enhancement on spinal MRI in pediatric Guillain-Barré syndrome.
Guillain-Barré syndrome diagnosis is based on clinical presentation and supportive diagnostic testing. In its early stage, no single, reliable diagnostic test is available. However, a finding of nerve root enhancement on spinal magnetic resonance imaging may be useful. ⋯ Patterns of enhancement were variable, but involved the thoracolumbar nerve roots in all patients. Enhancement of nerve roots with gadolinium on initial spinal magnetic resonance imaging was frequently present in these children with Guillain-Barré syndrome. Spinal magnetic resonance imaging is a sensitive diagnostic test and should be considered an additional diagnostic tool in select cases.

Case ReportsAnti-NMDA receptor encephalitis with atypical brain changes on MRI.
A young girl with antibodies to the N-methyl-D-aspartate receptor presented with a clinical syndrome suggestive of dyskinetic encephalitis lethargica with neuropsychiatric features at presentation, movement disorder, mutism, sleep disorder, and seizures. Persistent lesions in the white matter and pons were observed in magnetic resonance imaging of the brain, findings that have not been described previously in N-methyl-D-aspartate receptor antibody encephalitis.

Concussion or mild traumatic brain injury: parents appreciate the nuances of nosology.
We explored whether parents of our pediatric patients valued the diagnostic terms "concussion," "minor traumatic brain injury," and "mild traumatic brain injury" as equivalent or nonequivalent. 1734 of 2304 parents attending a regional pediatric emergency department completed a brief questionnaire assessing the equivalence or nonequivalence of the diagnostic terms "concussion," "minor traumatic brain injury," and "mild traumatic brain injury" in a pairwise fashion. Many parents viewed these diagnostic terms as equivalent, when assessed side by side. ⋯ As a group, parents reported that concussion or mild/minor traumatic brain injuries are valued equivalently. However, many parents considered them different, with concussion reflecting a "better" (or less "worse") outcome.

Case ReportsPediatric neuro-Behçet's disease responsive to adalimumab.
Neurologic manifestations of Behçet's disease (neuro-Behçet's disease) are uncommon, but may cause patients significant morbidity and mortality. Neuro-Behçet's disease is chronic and may be refractory to treatment. We report on a 12-year-old girl with neuro-Behçet's disease that responded to standard doses of subcutaneous adalimumab.

Review Case ReportsReversible posterior leukoencephalopathy induced by cancer chemotherapy.
Reversible posterior leukoencephalopathy, defined by both clinical and neuroimaging findings, can affect children receiving chemotherapy. The syndrome is characterized by hypertension, alterations in mental status, seizures, hallucinations, and acute visual changes and is associated with abnormalities seen in magnetic resonance imaging of symmetric white matter lesions, especially in the parietal and occipital lobes. ⋯ Presented here are four cases of reversible posterior leukoencephalopathy induced by chemotherapy, with a brief review of the literature and consideration of possible mechanisms. A diagnosis of reversible posterior leukoencephalopathy should be considered when patients receiving cancer chemotherapy suddenly develop hypertension followed by neurologic complications, especially if presenting with seizures.
