Sialolithiasis of an Accessory Parotid Gland Causing Mid-Cheek Pain.

A 52-year-old woman presented with a slightly painful swelling of the right cheek area without postprandial aggravation of the symptom last 1 week. On physical examination, an approximately 1.5 cm sized firm, slightly tender mass was palpated on the right mid-cheek region, and she did not show any abnormal findings on neurologic examination. Computed tomography showed a well-enhanced lesion with low density of internal portion in right cheek area, and tiny calcification was noted within internal low-density portion of cheek mass. These findings suggested sialolithiasis of an accessory parotid gland with duct dilatation. Mid-cheek pain with conservative medical treatment was resolved and has not occurred during 1 year follow-up.
