ABSTRACT

Se analiza el papel de la radiocirugía en un caso de meduloblastoma multirrecidivado del adulto tras dos intervenciones, radioterapia fraccionada, quimioterapia y dos autotrasplantes. Se resalta la precocidad de la respuesta clínico-patológica al tratamiento radioquirúrgico (AU)


The role of radiosurgery after multimodality treatment of recurrent desmoplastic adult medulloblastoma is analyzed. The ultra-early clinical and pathological response of this tumor to adjunctive radiosurgery is stressed (AU)

ABSTRACT

La radio necrosis y el edema cerebral son complicaciones asociadas a la radiocirugía. Presentamos los casos de tres pacientes tratadas con radiocirugía mediante acelerador lineal, de un meningioma de polo frontal izquierdo, peñasco y para sagital parietooccipital, respectivamente, que desarrollaron, entre dos y ocho meses más tarde, lesiones de tipo radio necrótico con extenso edema peritumoral que resultaron resistentes al tratamiento con esteroides y que se han resuelto con la administración de 40 sesiones de oxígeno hiperbárico. Son pocos los casos publicados hasta ahora en la literatura con tan excelentes resultados, por lo que consideramos un hecho a tener muy en cuenta ante las posibles complicaciones de este tipo que puedan presentarse en el transcurso de la práctica radioquirúrgica antes de recurrir a la cirugía (AU)


Radionecrosis with brain edema is a complication of radiosurgery. Three female patients harbouring a frontal pole, petrous and parasagital parietoocipital meningiomas respectively who had been treated with LINAC radiosurgery are presented. Those patients developed, between two and eight months later, a severe symptomatic radionecrosis with a huge brain edema resistant to the usual steroid therapy. Only after 40 sessions of hyperbaric oxygen, a good remission of the lesions was obtained. There are few cases reported in the literature with such a good outcome. Consequentely, this therapy must be taken into account to treat this type of radiosurgical complication before considering surgery (AU)
