GLIOMA NERVIO OPTICO PDF

La exploración oftalmológica reveló, mediante resonancia nuclear magnética, la presencia de un glioma de curso silente en el nervio óptico del ojo izquierdo. While 1 or 2 cases of primary glioma of the optic nerve are reported each year in the Barraquer, J.: Mixoma quistico del nervio optico de la papila y retina. El meningioma primario de la vaina del nervio óptico es un tumor raro, . Este signo nos permite diferenciarlo del glioma del nervio óptico.

Otero II ; V. Primary optic nerve sheat meningioma ONSM is a rare tumor, whose diagnosis and therapeutic management have varied in a substantial manner over the last few years. The appearance and development of diagnostic imaging techniques such as High Resolution Computerized Tomography and Nuclear Magnetic Resonance have allowed earlier and more precise diagnoses. The introduction of conventional radiation therapy in the late s, alone or in combination with surgery, and above all the introduction of Fractionated Stereotactic Radiotherapy and Three-Dimensional Conformal Intensity-Modulated Radiotherapy 3DCRT have optiico very efficient alternative therapies with a relatively low toxicity.

In this article we first review the embryological development, anatomy, natural history, and surgical treatment, and then describe the otico of radiotherapy RT in the considered entity, indicating how it can be integrated in the pattern of present day care. We analyse the different radiotherapy techniques, from the most elementary, such as conventional RT, followed by 3DCRT up to the most sophisticated such as Stereotactic Fractionated Radiotherapy, all based on our experience in one case.

En el momento del diagnostico estaba en tratamiento con suplementos de calcio y calcitonina por osteoporosis. Se realizaron las siguientes exploraciones complementarias. Cuando invade el globo ocular puede producir un desprendimiento de retina.

En casos muy avanzados pueden afectar a estructuras vitales y producir muerte del paciente 3. En ocasiones podemos ver calcificaciones del nervio o hiperostosis en los huesos vecinos El papel de la Radioterapia.

Otro hecho destacable es la ausencia, de complicaciones derivadas optlco tratamiento durante todo el periodo de seguimiento. Uno de los pacientes permanece estable, sin evidencia de deterioro visual o enfermedad progresiva.

En ella se trataron 39 pacientes 15 primarios y 24 secundarios. La dosis total administrada fue de 54 Gy en 30 fracciones. La mediana de dosis total fue de 51 Gy. Esto es especialmente evidente cuando administramos dosis totales por debajo de los 54 Gy, con un fraccionamiento convencional que no supere los incrementos de dosis diarios de 2 Gy Patrick A Sibony, Howard T.
