Inflammatory and infectious lesions of the neck

Diagnostic imaging is frequently used to evaluate the patient who has or may have an infection or other inflammatory lesion in the neck.

This review will illustrate the imaging appearance of many of the common inflammatory conditions that may arise in the neck. In most, but not all cases, CT is the imaging study of choice in the initial work-up of this patient population.
