title: [Radiation-induced intracerebral sarcoma].
abstract: We report a case of radiation-induced sarcoma in a 50 year-old male patient who was treated with total resection and radiation for right temporal lobe PNET. He received a dose of 60-Gy. A sequential magnetic resonance image 32 months after the completion of radiation therapy and 34 months after surgery showed a mass in the right temporal cerebral convexity. The postoperative diagnosis was sarcoma. Two years later the patient was operated because of a new lesion with similar characteristics. The follow up from the PNET diagnosis is 5 years and 10 months and the survival from sarcoma diagnosis is now 3 years and there is no evidence of recurrence. The development of sarcoma subsequent to cranial irradiation is an infrequent event but it should be considered in the differential diagnosis of a lesion that progresses several years after radiation therapy or when a new lesion appear.
