Coronal reformation shows the mass to be elongated and extending towards the axilla following rhe course of the cervico-brachial plexus.. X-ray confirms a circular object apparently lodged in the esophagus. Each parotid is wrapped around the mandibular ramus, and secretes serous saliva through the parotid duct into the mouth, to facilitate mastication and swallowing and to begin the digestion of starches. The role of plain films in evaluation of soft tissues of the neck is limited, but when the patients airway is threatened, plain film may offer the only safe imaging modality. Further extension may occur into the parapharyngeal, masticator, and/or submandibular spaces.
