title: Brain metastases in patients with pelvic or abdominal malignancy do not prevail in the posterior fossa: a retrospective study.
abstract: Pelvic and gastrointestinal tumors are generally considered to have a predilection to metastasize to the posterior fossa rather than to the supratentorial brain. Review of imaging of 100 patients with brain metastases from pelvic and gastrointestinal primary tumors and of 100 patients with brain metastases from other primary tumors did not reveal a difference in distribution of brain metastases between the two groups of patients. So, there is no evidence that pelvic and gastrointestinal tumors metastasize preferentially to the posterior fossa.
