Magnetic resonance imaging (MRI) has proven to be an ideal examination for evaluating a variety of soft tissue lesions in the extracranial head and neck. In this article we will describe the MRI characteristics of a variety of the soft tissue lesions found in the neck. Pathophysiology, clinical presentation, treatment, and prognosis are also discussed.

The manifestations of infectious disease of the spine are numerous. Viruses commonly affect the spinal cord and meninges, while tuberculosis and various bacterial and fungal organisms may involve the vertebrae, intervertebral disks, epidural and paraspinal regions, the leptomeninges, and, rarely, the cord itself. Magnetic resonance imaging, with its multiplanar capability and superb contrast resolution, is definitely the modality of choice in evaluating the patient with suspected infection of the spinal column or spinal cord and its coverings. The addition of postcontrast images is often helpful in the differential diagnosis.

ReviewNeuroradiologic evaluation of pediatric craniocerebral trauma.
Although cranial computed tomography (CT) remains the initial diagnostic test in the evaluation and triage of the pediatric head-injury patient, magnetic resonance imagining (MRI) has become the next step in the diagnostic evaluation of those with focal or diffuse neurologic deficits. MRI is better able to demonstrate the extent and location of both hemorrhagic and nonhemorrhagic injury, thereby providing prognostic information. In nonaccidental head injury, MRI has proved valuable in detecting subtle subacute contusions and even not so subtle chronic subdural hematomas that may be difficult to see on CT or that can mimic enlargement of the subarachnoid space on CT.

This article discusses the neuroradiologic characteristics of central nervous system infections in children. These disorders are divided into two groups: those of congenital infections and those of infections in the infant and child. ⋯ The heterogeneous etiologies often can be suggested by the neuroradiologic findings, as demonstrated with computed tomography and magnetic resonance imaging. This article also addresses the sequelae of destructive brain injuries.
