[Atypical thyrogloss cyst]. / Quiste tirogloso atípico.

UNLABELLED: The thyrogloss cysts present themselves usually as unique tumorations in the anterior cervical zone, more frequently in the second decade of life and affecting equally the two sexs. They move typically with the movements of deglution and can increase its volume with infections processes. In seldom occasions, the thyrogloss cysts can present symptoms as dysphonia, dysphagia or dyspnea facts that can suggest its laryngeal extension. METHODS: We present a case of a patient affected by dysphonia of long evolution, associated to the presence of a cervical mass. The CT showed a cervical cyst with extension to the left preepiglottic and paraglottic space with compression of the left thyroid wing. Although the clinic impression was a laryngeal neoplasia, the CT helped to realize the diagnosis ofthyrogloss cyst. During the surgery the thyrogloss cyst was removed with success, with the technique of Sistrunk and the patient recovered the voice. CONCLUSIONS: We present this case and realize a bibliographic revision on thyrogloss cysts, with atypical symptoms. We discuss also the role of CT in the diagnostic process in these types of processes.

Quiste tirogloso atípico / Atypical thyrogloss cyst

Los quistes tiroglosos se presentan habitualmente como tumoraciones únicas en la zona cervical anterior, más frecuentemente en la segunda década de la vida y afectando por igual a ambos sexos. Se desplazan típicamente con los movimientos deglutorios y pueden aumentar de tamaño con los procesos infecciosos. En raras ocasiones, los quistes tiroglosos cursan con síntomas tales como disfonía, disfagia o disnea hecho que debe sugerirnos la extensión laríngea del mismo. Métodos: Se presenta el caso de un paciente con una disfonía de de larga evolución asociada a la presencia de una masa cervical. La TAC mostró un quiste cervical con extensión hacia el espacio preepiglótico y paraglótico izquierdo con compresión del ala tiroidea izquierda. A pesar de que la impresión clínica era la de una neoplasia laríngea, la TAC ayudó a realizar el diagnóstico de quiste tirogloso. Durante la cirugía, el quiste tirogloso fueextraído con éxito mediante la técnica de Sistrunk y el paciente se recuperó de su disfonía. Conclusiones: Se presenta este caso y se realiza una revisión bibliográfica sobre quistes tiroglosos que cursan con síntomas atípicos. Asimismo se discute el papele de la TAC en el proceso diagnóstico de este tipo de procesos
