Computed tomography of cervical infections.

Computed tomography of 31 patients with infections of the face and neck was reviewed and correlated with the clinical and surgical results. Computed tomography was found to be valuable for (a) distinguishing cellulitis from abscess, (b) defining the precise location and extent of complex infections, (c) demonstrating secondary complications, and (d) occasionally suggesting the etiology of infection. Based on this review, we concluded that CT provides important diagnostic information that aids clinical assessment and guides medical and surgical management of cervical infections. The anatomic relationships of selected cervical spaces are reviewed with respect to pathways of spread and potential complications of cervical infections.
