Brain metastasis: first sign of colorectal carcinoma.

The purpose of this study was to describe the detection of a brain metastasis as the first sign of colorectal carcinoma, without any liver and/or lung involvement. This finding demonstrates primarily the need for regular central nervous system investigation in diagnosing colorectal cancer and secondly that further, more thorough research into the biomolecular events involved in metastases from colorectal cancer is warranted.
