Haemostatic material (Surgicel^®) mimicking residual tumour: magnetic resonance imaging findings in operated pediatric neuro-oncology cases

Surgical resection is the first line treatment in the majority of pediatric brain tumors. Even in cases when total resection is not possible, a subtotal debulking is used to reduce mass effect and to provide tissue for histological and molecular diagnosis, necessary to guide oncologic therapies, to assess risk stratification and to predict prognosis (1-3).
