The Diagnosis of Tumours Involving the Parapharyngeal Space by Computed Tomography

Tumours arising within or adjacent to the parapharyngeal space are usually large at presentation and present difficulties in the choice of surgical approach. The findings on contrast-enhanced computed tomography (CT) of 30 patients with mass lesions in this region are presented. Contrast-enhanced CT can provide reliable information regarding the size and extent of a mass, its site of origin and likely histological type, as well as its relationship to surrounding neurovascular structures.
