There is a wide variety of disease entities in children, which can present with cervical adenopathy. The spectrum of pathology and imaging appearance differs in many cases from that seen in adults. This review aims to compare the strengths and limitations of the various imaging modalities available to image pediatric patients presenting with cervical adenopathy, provide guidance on when to image, and highlight the imaging appearance of both common and uncommon disorders affecting the cervical nodes in children to aid the radiologist in their clinical practice.

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.

Pattern recognition of specific temporal bone radiological phenotypes, in association with abnormalities in other organ systems, is critical in the diagnosis and management of syndromic causes of hearing loss. Several recent publications have demonstrated the presence of specific radiological appearances, allowing precise genetic and/or syndromic diagnosis, in the right clinical context. This review article aims to provide an extensive but practical guide to the radiologist dealing with syndromic causes of hearing loss.
