Peritumoral oedema (Swelling around the tumor) is a well known complication of the the surgery performed in brain tumors and coticosteroids like dexamethasone (decadron) are generally the first choice drugs to control the oedema, and the oedema resolves in a few weeks in most cases.
However, in your husband's case, the oedema has not resolved even after being on therapy woth decadron for a long time. Please consult your doctor, and ask for a change in treatment as persistent oedema can lead to an increase in the intracranial tension (pressure inside the brain) and cause problems. Maybe a dose change of decadron or the use of some other alternative agents like hyperosmolar solutions of sugar, urea, mannitol, or glycerol may help.
