Legend Post contrast axial CT images at the level of the oropharynx demonstrate soft tissue swelling overlying the left parotid gland. The left parotid gland is expanded and partially replaced by intermediate attenuation material, with involvement including the deep lobe of the parotid. A rim of contrast enhancement surrounds this collection. The retromandibular vein is displaced medially and the left mandibular condyle anteriorly.

Legend Follow up images show greater anterior extension of the lesion with reduced attenuation centrally. There is now clearly a mixture of gas and fluid expanding the left parotid. Inflammatory changes extend anteriorly to involve the masseter muscle, as well as the sternocleidomastoid muscles posteriorly. There is also effacement of the parapharyngeal fat at the left oropharynx. Rim enhancement is more discrete. The left common carotid artery and jugular vein remain patent.
