Right chronic parotidis. There is an ovoid low T1 and T2 structure within parotid duct along the anterior aspect of the right parotid gland that measures 4 mm in width and 10 mm in length, which is compatible with a calculus. There is an additional low T1 and T2 structure within parotid duct compatible with a calculus overlying the anterior masseter muscle, measuring 3 mm in length and 2 mm in width. There is dilatation of the parotid duct up to 6 mm over a length of 25 mm between the two calculi. However, the duct is relatively narrow focally just anterior to the larger calculus. There is also mild diffuse intraparotid ductal dilatation, as well as considerable thickening and enhancement of the walls of the right parotid duct. There is also extensive enhancement of the right parotid gland and overlying subcutaneous tissues, but no evidence of abscess or discrete tumor. There are mild prominent right parotid lymph nodes, which are likely reactive. The left parotid gland appears to be unremarkable. There is fluid and mild mucosal thickening within the right maxillary sinus. There is a partially-characterized left supraclinoid internal carotid artery aneurysm that measures up to approximately 15 mm.
1. Acute upon chronic right parotitis and overlying cellulitis associated with parotid sialodocholithiasis and ductal dilatation.2. Findings compatible with acute rhinosinusitis.3. Partially-characterized left supraclinoid internal carotid artery aneurysm that measures up to approximately 15 mm.
