Stage 4 glioblastoma MRI

MRI uses magnetic fields and radio waves to create detailed images of the brain. Contrast dye may help the radiologist see areas where the blood–brain barrier has changed. A bright or enlarging area can reflect tumour, swelling, treatment effect, bleeding, or a mixture of changes. Radiologists compare current and earlier scans and describe location, size, surrounding swelling, and pressure on nearby brain structures. The phrase stage 4 is not commonly used in the same way for glioblastoma as it is for many other cancers.

Your neuro-oncology team may combine MRI findings with tissue diagnosis, neurological examination, and your daily function. Surgery may obtain tissue or remove as much visible tumour as safely possible. Radiotherapy and chemotherapy may then be discussed, with the schedule shaped by health and recovery. Ask whether a new change could be treatment effect and whether further imaging or specialist review is needed. Clinical trials may be an option for some people.

Seek emergency help for a first seizure, repeated seizures, sudden weakness, new difficulty speaking, severe confusion, loss of consciousness, or a sudden severe headache with vomiting. Contact the treating team promptly for worsening balance, vision changes, increasing drowsiness, or a persistent new symptom.

What does the MRI show compared with my earlier scan? Could this be tumour, swelling, or treatment effect? Is tissue confirmation available? What symptoms require immediate help?
