Acinic cell carcinoma of the parotid gland: a case report and review of the literature

Ilson Sepúlveda et al. Case Rep Oncol. .

Abstract

We report on a patient who was referred to the ENT service following an incidental finding on an MRI scan of the brain. It revealed a mass in the right parapharyngeal space, and additional imaging confirmed the presence of a solid cystic expansive mass with moderate enhancement following contrast media injection. The patient was treated with a total parotidectomy followed by radiotherapy. Currently, the patient is disease-free without any complications.

Keywords: Computed tomography; Magnetic resonance imaging; Parapharyngeal space; Parotid gland; Tumor.
