Metachronous gliomas following cranial irradiation for mixed germ cell tumors.
BACKGROUND
Cranial irradiation has been widely used as a therapeutic tool for treating various lesions, particularly neoplastic diseases. Even though radiation therapy is usually well-tolerated, it occasionally causes clinically significant long-term toxicity such as radiation necrosis and irradiation-related arteriopathy with stroke.
The development of neoplasms following therapeutic cranial irradiation is also rare, but may cause serious and potentially fatal complications. Various radiation-induced tumors, including meningioma, glioma, and sarcoma have been reported (Child Nerv Syst 24:793-805, 12). However, metachronous intracranial double tumors induced by radiation therapy are extremely rare. In here, we report a case of metachronous different gliomas including astrocytoma and glioblastoma following irradiation therapy after 41 and 46 months, respectively.
