Tumors of the parapharyngeal space originate from the various tissues that are present within this space or from neighboring structures that directly extend or spread lymphogenously or hematogenously into the parapharyngeal space.1 The most prevalent tumors are salivary gland tumors (eg, pleomorphic adenoma, monomorphic adenoma, mucoepidermoid tumor, acinic cell tumor) and carcinoma and neurogenic tumors (eg, neurilemmoma/schwannoma, neurofibroma, ganglioneuroma/ganglioneuroblastoma, neuroblastoma, and paraganglioma). Also, a wide variety of benign and malignant primary tumors have been found in the parapharyngeal space.
