This session looks at the use of the various imaging modalities to identify a mass lesion as a metastasis and suggest its organ of origin in order to direct further imaging and clinical management.


By the end of this session you will be able to:
• Distinguish extra-axial from intra-axial tumours
• Know the frequency with which different non central nervous system primary tumours spread to the intracranial compartment
• Recognise the commoner patterns of metastases using the different imaging modalities
• Know how informed reporting can affect clinical management
• Recognise the appearance of metastases on CT and MRI, including the response of the lesion to the administration of intravenous (IV) contrast Metastases should enhance
• Distinguish spread of tumour from the skull vault and skull base into the brain from lesions that are metastases in the dura, leptomeninges or parenchyma
• Recognise carcinomatous encephalitis and be able to distinguish limbic encephalitis especially from oat cell carcinoma with the differential diagnosis being from herpes simplex encephalitis
• Select the most useful imaging modality to accurately assess the likelihood of a mass being a primary tumour versus a metastasis
• Recognise the value of different imaging modalities to display bone versus brain deposits as discovery of even a solitary brain metastasis greatly alters the management and prognosis of the cancer patient
• Predict the possible primary site of origin of a metastasis to guide the clinician down a diagnostic pathway which will contribute to clinical management
• Identify the features of imaging post therapy, including the differential diagnosis of the appearances
