A veces se usa la quimioterapia, especialmente para tumores recurrentes. Pueden producirse en el cerebro y la columna. Puede ser necesaria la radioterapia si no pudiera extirparse todo el tumor. Estos tumores pueden diseminarse a otros sitios del cerebro. Otros gliomas se denominan en base a la parte del cuerpo que afectan. A menudo los cordomas se producen cerca de la parte superior o inferior de la columna, fuera de la duramadre, y pueden invadir el canal espinal y la cavidad craneana.

Generalmente los meningiomas crecen lentamente, generalmente no invaden los tejidos circundantes normales y raramente se diseminan a otras partes del SNC o el cuerpo. Los tumores pineales son responsables de alrededor del uno por ciento de los tumores cerebrales. Los tumores pituitarios son responsables de alrededor del 10 por ciento de todos los tumores cerebrales primarios.

Puede estar presente en el nacimiento o desarrollarse con el tiempo. Cerca de la mitad de aquellos pacientes que padecen esclerosis tuberosa desarrollan astrocitomas benignos. Cada persona es diferente.Las neuronas vegetativas son muy variables en su aspecto, de acuerdo con su distinto estado funcional.

The objective of this review is to describe the study technique of Magnetic Resonance Neurography as well as the characteristics of the normal and pathological peripheral nerve.
