Radiation-induced brain tumours in nevoid basal cell carcinoma syndrome: implications for treatment and surveillance.

Introduction: We report two cases of radiation-induced intracranial tumours after treatment for medulloblastoma presenting in children with nevoid basal cell carcinoma syndrome.

Discussion: These cases illustrate the need for judicious use of post-operative radiotherapy as secondary tumors are commonly reported. This is particularly important as the initial tumour in this cohort is of the 'less aggressive' desmoplastic subtype.
