This is just prior to the shunt surgery, 7 months after radiation.

Gray areas in the tumor show where the blood circulation is impaired because of tumor cell death and consequently not taking up the dye that highlights the tumor.

It is uncertain whether the significant increase in size is due to further tumor growth, or to edema* due to radiation insult/injury. If it is edema, it should subside on it's own after a period of time - although that may be a year or more.

* (edema: swelling caused by an abnormal accumulation of fluid in body tissues)
