Anti-N-methyl-D-aspartate (NMDA) receptor encephalitis is a severe but potentially reversible neurologic disorder that is clinically recognizable in children and adolescents. Prompt diagnosis and treatment are essential to facilitate recovery. ⋯ Patients with tumor-associated encephalitis benefit from tumor resection. More than 75% of patients make a substantial recovery, which occurs in the reverse order of symptom presentation associated with a decline in antibody titers.

ReviewStandardized magnetic resonance imaging acquisition and reporting in pediatric multiple sclerosis.
Magnetic resonance (MR) imaging is one of the most important paraclinical tools for the diagnosis of multiple sclerosis (MS), and monitoring of disease progression and treatment response. This article provides clinicians and neuroradiologists caring for children with demyelinating disorders with a suggested standard MR imaging acquisition and reporting protocol, and defines a standard lexicon for lesion features typical of MS in children. As there is considerable overlap between the MR imaging features of pediatric- and adult-onset MS, the recommendations provided herein may be of relevance to radiologists and clinicians caring for adults with multiple sclerosis.

ReviewPediatric multiple sclerosis: pathobiological, clinical, and magnetic resonance imaging features.
In this article, the pathobiological, clinical, and treatment aspects of pediatric-onset multiple sclerosis (MS) are summarized, and the conventional magnetic resonance (MR) imaging (ie, T1-weighted, proton-density, and T2-weighted imaging) features of MS in children are discussed, as well as the application of MR imaging in the diagnosis of pediatric-onset MS and in prediction of MS in children with an incident central nervous system demyelination. Insights gained from studies comparing MR imaging features of pediatric-onset and adult-onset MS are presented.

Inflammatory brain diseases in childhood are underrecognized and lead to devastating yet potentially reversible deficits. New-onset neurologic or psychiatric deficits in previously healthy children mandate an evaluation for an underlying inflammatory brain disease. ⋯ Clinical symptoms, initial laboratory test, and neuroimaging studies help to differentiate between different causes; however, more invasive tests, such as lumbar puncture, conventional angiography, and/or brain biopsy, are usually necessary before the start of treatment. This article focuses on childhood CNS vasculitis.

ReviewPitfalls in the staging of cancer of the oropharyngeal squamous cell carcinoma.
The face of oropharyngeal squamous cell carcinoma (OPSCC) is changing. It has a dichotomous nature, with 1 subset of the disease associated with tobacco and alcohol use and the other having proven association with human papilloma virus infection. Imaging plays an important role in the staging and surveillance of OPSCC, and a detailed knowledge of the anatomy and pitfalls is critical. This article will review the detailed anatomy of the oropharynx and epidemiology of OPSS, along with its staging, patterns of spread, and treatment.
