Brain tumour post-treatment imaging and treatment-related complications

ConclusionAlthough radiological evaluation of brain tumours after treatment can be quite challenging, knowledge of the various imaging techniques available can help the radiologist distinguish treatment response from tumour progression and has the potential to save patients from inappropriate alterations in treatment. In addition, knowledge of common post-treatment-related complications that can be identified on imaging can help the radiologist play a key role in preventing significant patient morbidity/mortality.Teaching points•Contrast enhancement does not reliably define tumour extent in many low-grade or infiltrative gliomas.•Focal regions of elevated cerebral blood volume (rCBV) on dynamic susceptibility contrast (DSC) perfusion-weighted imaging are suggestive of tumour growth/recurrence.•Brain tumour treatment response criteria rely on both imaging and clinical parameters.•Chemotherapeutic agents can potentiate many forms of radiation-induced injury.•Ipilimumab-induced hypophysitis results in transient diffuse enlargement of the pituitary gland.
