Unusual presentation of parotid gland adenoid cystic carcinoma : A case presentation and literature review.

Adenoid cystic carcinoma (ACC) represents approximately 10 of all epithelial salivary neoplasms and most commonly involves the parotid gland. We report CT and MRI finding of a 38-year-old young man presented to our ENT department with 02 years history of an external auditory canal stenosis. Physical examination revealed bilateral parotid gland swelling with a complete stenosis of the left external auditory canal.
