Patient: description of disease (onset time, main symptoms, hospital, etc.): December 2, 2010 craniotomy, 26 days after the operation after 30 radiation therapy, chemotherapy for 3 months. On May 30, 2011, I had a drain because there was a sac in my head, and it worked well after that! But the water in the sac grew back in less than a week. On August 17, 2011, I had an MRI and the results were not good. The capsule is much bigger than before and there is a large area of edema. There are also recurrent tumors around the capsule. Radiotherapy: Centurion Chemotherapy: Temozolomide Tadol The results were fair, what is the next step now? Do we need another surgery? Or do I need a lateral ventriculoperitoneal shunt But I am worried if the tumor will metastasize into the abdominal cavity by hand? Causing tumors to appear in the abdominal cavity?
