Recurrent Spinal Cord Cystic Astrocytomas: Treatment with Rhenium-186 Intracavitary Radiation

摘要: Endocavitary irradiation or brachytherapy is frequently used for the treatment of intracranial cystic tumors. This can also be to treat low-grade astrocytoma spinal cord in very specific case symptomatic recurrent cysts, despite repetition classical methods such as surgery CT scan guided taping. We use 186 Rhenium isotope, which able penetrate cyst wall from 1 2 mm. The isotope injected using a scan, checks position top needle during taping and after its opacification with iodine contrast. Follow-up consists MR every 3–6 months. A second injection may performed if keeps growing.
