Parapharyngeal and deep lobe parotid tumors.
Lesions in the parapharyngeal region are more difficult to evaluate or differentiate clinically. Conventional films are of limited use in studying this area because of its soft tissue composition. Alternatively, CT can display the soft tissue structures, including the fascial planes and deeper tissues of this region extremely well. Differentiation between parapharyngeal and deep lobe parotid tumors can be made. Patterns of enhancement and tumor location are noted. Size and extent of tumors, including operability, can be assessed. Probable pathology may be suggested. Parapharyngeal anatomy and pathology are illustrated and discussed.
