Inflammatory lesions of the neck, including fascial spaces--evaluation by computed tomography and magnetic resonance imaging.

The clinical findings that characterize inflammatory lesions of the neck are briefly presented. The technique of the major imaging methods--computed tomography (CT) and magnetic resonance imaging (MRI)--used for the evaluation of these lesions is described as well as the radiologic appearance of abscesses, enlarged lymph nodes and cellulitis. The only advantage of MRI over CT is its multiplanar capability, sagittal sections being especially useful in the demonstration of the retropharyngeal space.
