1/2. Radiation-induced meningioma evaluated with positron emission tomography with fludeoxyglucose F 18.We describe a patient with radiation-induced meningioma 12 years after cranial irradiation for ectopic germinoma. PET scans with fludeoxyglucose F 18 showed a high glucose metabolic rate in the meningioma despite a benign histologic appearance.- - - - - - - - - - ranking = 1keywords = radiation-induced (Clic here for more details about this article) |
2/2. Vasoreconstructive surgery for radiation-induced vasculopathy in childhood.BACKGROUND: Cerebral vasculopathy associated with the appearance of netlike vessels can develop following irradiation therapy for parasellar brain tumors, especially in children. However, little is known regarding the clinical course of this disease or the appropriate therapy for it. case reports: We experienced two surgically-treated patients with radiation-induced vasculopathy and reviewed the previously reported cases. Both of our patients were treated with encephalo-duro-arterio-myo-synangiosis combined with superficial temporal artery to middle cerebral artery (STA-MCA) bypass. Their ischemic symptoms improved following the surgery, associated with a good angiographic neovascularization from the STA-MCA bypass, as well as dural and muscular arteries. CONCLUSION: Our findings and the review of the previous reports suggested that surgical therapy may be beneficial for the patients with radiation-induced vasculopathy with the appearance of netlike vessels.- - - - - - - - - - ranking = 6keywords = radiation-induced (Clic here for more details about this article) |
