Introduction and objectives: The intralabyrinthine schwannoma is a rare benign tumor, with extradural slow growth, located primarily in the membranous labyrinth. Through a clinical case, we present the characteristics of its evolution, we try to offer a physio-pathological explanation of symptoms and audio-vestibular findings and finally, we describe the therapeutic options. Description: We present a 59 year old woman, beginning with non-specific symptoms of the left ear and then concerned because of a hearing loss in that ear. To confirm that it is a non-justified unilateral hearing loss , MRI was requested and it shows the presence of a small intravestibular tumor of 2-3 mm which we will review periodically. Discussion: The origin and the prevalence of intralabyrinthine schwannomas are unknown. Even though the clinic is confused with other frequent otological processes, the implementation of MRI would increase the number of diagnosed cases. Depending on the patient, their symptoms, evolution and tumor characteristics, the type of treatment is decided. Conclusion: Intralabyrinthine schwannoma should be part of the differential diagnosis in patients with unilateral audio-vestibular symptoms and request a high resolution MRI to obtain the definitive diagnosis. Presenting an excellent prognosis, the observation is considered the best treatment option. |

A través de un caso clínico presentamos las características de su evolución, intentamos ofrecer una explicación fisiopatológica de la sintomatología y de los hallazgos audio-vestibulares y describimos finalmente, las diferentes opciones terapéuticas. Descripción: Se trata de una mujer de 59 años, que comienza con síntomas inespecíficos del oído izquierdo a los que posteriormente se añade una pérdida auditiva. Al confirmar que se trata de una hipoacusia unilateral no justificada, solicitamos una RM que pone de manifiesto la presencia de un pequeño tumor de 2-3 mm intravestibular, al que revisaremos periódicamente. Discusión: El origen y la prevalencia del schwannoma intralaberíntico son desconocidos. Aunque la clínica se confunde con la de otros procesos otológicos más frecuentes, la realización de RM incrementaría el número de casos diagnosticados. En función del paciente, de su sintomatología, de la evolución y de las características tumorales, se decide el tipo de tratamiento Conclusión: El schwannoma intralaberíntico debe formar parte del diagnóstico diferencial en pacientes con síntomas audio-vestibulares unilaterales y solicitar una RM de alta resolución para obtener el diagnóstico definitivo. Presentando un pronóstico excelente, la observación es considerada como la mejor opción terapéutica.2016text (article)https://dialnet.unirioja.es/servlet/oaiart?codigo=5403442(Revista) ISSN 2171-9381Revista ORL, ISSN 2171-9381, null 7, Vol. 1, 2016, pags. 57-62spaLICENCIA DE USO: Los documentos a texto completo incluidos en Dialnet son de acceso libre y propiedad de sus autores y/o editores.
