Thromboembolic toxicity observed with concurrent trametinib and lenalidomide therapy.

The event-free survival of pediatric low-grade gliomas is poor, and patients often require multiple treatment strategies. While MEK and RAF inhibitors are efficacious in early-phase trials, not all patients respond, and many experience progression following completion of therapy. Evaluating combination therapies that may enhance efficacy or prolong disease stabilization is warranted.

Imaging of Macrocephaly.

Macrocephaly is a common diagnosis in the pediatric population, particularly in the infantile time period. There is a wide range of causes of macrocephaly, from benign to malignant, for which imaging plays a key role in the diagnosis and clinical guidance. Our aim is to review the distinct and prevalent neuroimaging findings in the evaluation of the macrocephalic infant.

Isolated lesions of the suprasternal notch in pediatric patients.

Background: Palpable masses of the head and neck are a common indication for imaging in the pediatric population. Midline lesions of the infrahyoid neck, particularly lesions isolated to the suprasternal notch, are not well studied.

Objective: To delineate the histopathological and imaging spectrum of masses that occur within and isolated to the suprasternal notch.

High-resolution CT findings of pulmonary interstitial glycogenosis.

Background: Pulmonary interstitial glycogenosis is a form of childhood interstitial lung disease characterized by the histological finding of abundant glycogen-laden mesenchymal cells within the pulmonary interstitium. Patients present in the neonatal period with disproportionate respiratory distress. Often, pulmonary interstitial glycogenosis is accompanied by alveolar simplification complicating recognition and diagnosis.
