Tumour-to-tumour metastasis (CNS)

A tumour-to-tumour metastasis, which is also called collision tumour, is a rare metastatic process in which an extracranial metastasis metastasizes to an intracranial (usually benign) pre-existent tumour. The most common recipient of these extracranial metastases are meningiomas; the most common donor tumours are breast and lung cancers.
