Solitary and early brain metastases from colon carcinoma are unusual.
This possibility must be kept in mind, in patients with cerebral metas
tasis of unknown adenocarcinoma. These patients could benefit from col
onoscopy and CEA studies with the aim of achieving more early diagnosi
s and surgical resection. The case of a 48-year-oid woman with brain m
etastasis diagnosed 4 months before the primary tumor, a colon cancer,
is reported.
