MARTINEZ-LAGE, J.; SAN PEDRO, J. Ros de; MARTINEZ-PEREZ, M.  and  POZA, M.. Meningiomas after radiation-therapy for benign astrocytomas. Neurocirugía [online]. 2005, vol.16, n.3, pp.266-270. ISSN 1130-1473.

A 4.5 year-old-girl was submitted to subtotal removal of a benign astrocytoma of the left temporal lobe with basal ganglia extension and given radiotherapy. At age 27, she was found to harbor a right posterior frontal meningioma that was totally removed. A recurrence of the right convexity meningioma was again excised after a 4-year interval. The authors report this case to illustrate the possibility of the appearance of radiationinduced meningiomas after an interval of 22 years and briefly discuss 16 previous reports on this occurrence in benign astrocytomas.

Keywords : Radiation-induced meningioma; Radiation- induced neoplasms; Benign astrocytoma; Second neoplasms; Radiotherapy complications.
