Neck masses are frequent in the pediatric population and are usually divided into congenital, inflammatory, and neoplastic. Many of these lesions are cystic and are often benign. Solid masses and vascular lesions are relatively less common, and the imaging appearances can be similar. This article reviews the clinical presentation and imaging patterns of pediatric solid and vascular neck masses.

Neck infections are common in children, though the clinical presentation is often vague and nonspecific. Therefore, imaging plays a key role in identifying the site and extent of infections, evaluating for potentially drainable collections, and assessing for airway and vascular complications. This review focuses on imaging features associated with common and characteristic neck infections in children to include tonsillar, retropharyngeal, and otomastoid infections; suppurative adenopathy; superimposed inflammation or infection of congenital cystic lesions; and Lemierre syndrome.

In this article, we will describe relevant anatomy and imaging findings of extraocular and orbital rim pathologic conditions. We will highlight important clinical and imaging pearls that help in differentiating these lesions from one another, and provide a few practical tips for challenging cases.

Pediatric hearing loss is common with significant consequences in terms of language, communication, social and emotional development, and academic advancement. Radiological imaging provides useful information regarding hearing loss etiology, prognosis, therapeutic options, and potential surgical pitfalls. This review provides an overview of temporal bone imaging protocols, an outline of the classification of inner ear anomalies associated with sensorineural hearing loss and illustrates some of the more frequently encountered and/or important causes of non-syndromic hearing loss.
