Meningiomas del agujero magno y primeros segmentos cervicales
Resumen Se presentan 6 pacientes con meningiomas situados en el agujero magno recogidos durante los dos ultimos anos. La clinica inicial que presentaban fue totalmente inespecifica simulando la mayoriade ellos un cuadro de espondilosis cervical. El diagnostico morfologico de la lesion se baso en la TC y RM de fosa posterior y primeros segmentos cervicales. Con estas pruebas se confirmo la presencia de una masa tumoral, de caracter intradural y de contornos bien definidos, con presentacion lateral en 4 casos y anterior en 2.

Radiosurgery of Epilepsy
Since 1982 a series of 11 epileptic patients have been treated with stereotactic radiosurgery. Patients were intracranially recorded with cortical and deep electrodes until the location of the epileptogenic focus was determined. A deep electrode was stereotactically placed at this point to confirm the accuracy of the location. All patients received radiosurgery with a gamma source and a dose of 10 to 20 Gy, except two of them in which a betatron was used. The results were: Total disappearance of the crises and withdrawal of medication: 4 cases (36%). More than 80% reduction of crises: 3 cases (27%). More than 50% reduction of crises: 2 cases (18%). Less than 50% reduction of crises: 2 cases…
