Tumor fibroso solitario extra-intramedular de localización dorsal / Solitary fibrous tumor: A clinical case

Introducción: El tumor fibroso solitario (TFS) es un tumor poco frecuente de origen mesenquimal, que se localiza principalmente en pleura. De extraordinaria infrecuencia es su localización a nivel intraespinal, siendo la región torácica la más frecuente. Presentación del caso: Presentamos el caso de una paciente de 48 años con hipoestesia ascendente progresiva en miembros inferiores y mielopatía de un mes de evolución, que se diagnosticó de un tumor intraespinal en segmento D3-D4. Fue intervenida quirúrgicamente mediante abordaje dorsal posterior y laminoplastia D3-D4, hallándose un tumor intradural con componente intramedular, de 18×12mm, aproximadamente. La resección fue completa y la anatomía patológica resultó el diagnóstico de tumor fibroso solitario. La paciente, tras 7 meses de seguimiento se encuentra asintomática. Discusión: La resección completa tumoral junto con las características histopatológicas son los principales factores pronósticos, teniendo la cirugía un papel protagonista en este tipo de neoplasia. Conclusión: Son muy pocos los casos publicados en la literatura de tumor fibroso solitario con localización intraespinal. Con este artículo aportamos un nuevo caso a la misma

Introduction: Solitary fibrous tumor (TFS) is a rare tumor of mesenchymal origin, located mainly in the pleura. It is extraordinarily infrequent find it at the intraespinal level, being the thoracic region the most frequent. Case presentation: We present the case of a 48-year-old patient with progressive ascending lower limb and myelopathy of one month of evolution, with intraspinal location at the D3-D4 level. It was surgically operated by posterior dorsal approach and D3-D4 laminoplasty, with an intradural tumor with an intramedullary component of approximately 18×12mm. The resection was complete and the pathological anatomy gave the diagnosis of solitary fibrous tumor. The patient is currently asymptomatic. Discussion: Complete tumor resection and histopathological features are the main prognostic factors. Surgery have a main role in this type of neoplasia. Conclusion: There are few case published of solitary fibrous tumor with intraspinal localization. We apport another case to the literature
