The brain metastases by neuroanatomical site.
This figure is applicable in the diagnostic context; if the neuroanatomical site is known, it helps answer the question “How likely is a metastasis from a primary tumour that arose from ‘X’?”.

The brain metastases by primary site.
This figure is applicable in the pathobiologic context; if the primary site is known, it helps answer the question “How likely is a metastasis to the neuroanatomical site ‘Y’?”.
