ABSTRACT
This is a case report of a papillary thyroid carcinoma metastatic to the parapharyngeal space, that presented with local obstructive symptoms (dysphagia and displacement of the ipsilateral tonsil). The diagnosis was suspected by imaging studies (CT and MRI) but not confirmed until histological examination. It is not common for such tumors to metastasize to the parapharyngeal space. This is the reason why, to our knowledge, there have been described only five similar cases previously.

Se presenta un caso de metástasis de carcinoma papilar de tiroides de localización en el espacio parafaríngeo con clínica inicial de características obstructivas a nivel locorregional (disfagia progresiva y desviación contralateral de la amígdala correspondiente). En el estudio de imagen (TAC y RNM), la masa adoptaba una morfología especial, pero el diagnóstico no se confirmó hasta que se realizó el estudio anatomopatológico. Este espacio no es un lugar frecuente de asiento de metástasis ni de carcinomas tiroideos ni del resto de tumores de cabeza y cuello, por lo que, hasta la fecha, sólo se han descrito 5 casos similares en la literatura médica
