Abstract
Objective

To show the usefulness of magnetic resonance imaging in the anatomic and pathologic characterisation of the sellar region, emphasising the differential diagnosis of uncommon non-adenomatous tumors and pseudotumors studied in our institution.

Conclusion

The sellar region is a complex anatomic space with diverse types of tissues from which a wide spectrum of diseases can arise. Magnetic resonance imaging's high tissue resolution and ability to characterise the patterns of tumor growth and biological behaviour make it the best imaging technique to study this region.

Resumen
Objetivo

El propósito de este artículo es destacar la utilidad de la resonancia magnética en la caracterización anatómica y patológica de la región selar haciendo hincapié en diagnósticos diferenciales de tumores no adenomatosos y pseudotumores poco frecuentes estudiados en nuestra institución.

Conclusión

La región selar es un espacio anatómico complejo, con múltiples tipos de tejidos a partir de los cuales puede surgir un amplio espectro de patologías. La resonancia magnética es el mejor método por imágenes para estudiar esta región debido a su alta resolución tisular, la caracterización de los patrones de crecimiento tumoral y el comportamiento biológico.
