RESUMO
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.

Los coristomas neurogliales orofaríngeos son tumores de cabeza y cuello excepcionalmente raros que contienen tejido neuroglial maduro. Presentamos un caso de coristoma neuroglial centrado en la orofaringe y con extensión al espacio parafaríngeo que, hasta donde sabemos, es el único caso cuya apariencia simulaba circunvoluciones corticales cerebrales con una aparente diferenciación entre sustancia blanca y gris. Ilustramos y detallamos los hallazgos de imágenes por resonancia magnética del coristoma orofaríngeo que podrían ayudar a establecer un diagnóstico preoperatorio correcto.(AU)
