Giant Parapharyngeal Pleomorphic Adenoma with Intracranial Extension: a case report

Parapharyngeal pleomorphic adenoma (PA) is a benign tumor of the salivary glands. We report a rare case of giant benign parapharyngeal PA with intracranial extension in a 69-year-old male who presented with aural fullness. Magnetic resonance imaging (MRI) showed a large, lobulated, well-defined mass in parapharyngeal space with erosion of the base of the middle cranial fossa and extension to the paracavernous sinus region. The possibility of a benign PA should be included in the differential diagnoses when encountering a bulky parapharyngeal mass with intracranial extension.
