Odontogenic and sinogenic infections are frequently encountered in the pediatric population. Although the diagnosis is often suspected clinically, imaging can play a significant role in localizing the site of infection, assessing for involvement of deep neck spaces, detection of abscess and other potentially life-threatening complications, and providing valuable information to help with treatment planning. This article reviews the general imaging considerations and anatomy relevant to odontogenic and paranasal sinus infections and describes the salient clinical and imaging features of infectious diseases of the dentition and sinuss.

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.

ReviewIntradural Extramedullary Tumors and Associated Syndromes.
Most intradural tumors are located within the intradural extramedullary compartment, and the most common tumors are schwannomas and meningiomas. Other less common neoplasms include neurofibroma, solitary fibrous tumor, myxopapillary ependymoma, lymphoma, metastatic leptomeningeal disease, malignant peripheral nerve sheath tumor, and paraganglioma. ⋯ MRI is the modality of choice for detecting and evaluating intradural extramedullary spinal tumors. This imaging technique helps narrow the differential diagnosis and therefore decide treatment.
