Oropharyngeal neuroglial choristoma with extension into the parapharyngeal space

Oropharyngeal neuroglial choristomas are exceptionally rare head and neck tumours that contain mature neuroglial tissue. We report a case of neuroglial choristoma centred in the oropharynx and extending into the parapharyngeal space that, to the best of our knowledge, is the only case whose appearance simulated brain cortical gyri with an apparent differentiation between white and grey matter. We illustrate and detail the magnetic imaging findings of oropharyngeal choristoma that might help to establish a correct preoperative diagnosis.
