Resumen
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.

Abstract
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.
