hello. Welcome to HCM.
is the common way by which brain cells react to any kind of injury/ Damage/ surgery. It is also the mode of so-called repair in brain. By, itself, gliosis does not indicate recurrence. Whether in future, the patient will have recurrence depends on the type of tumour, the WHO grading, other co-morbid conditions and completeness of surgery to name a few. The best approach is to be on a routine follow up as suggested by operating neuro-surgeon as he/ she is the best person to guide you for future prospects.
