Intracranial brain metastasis from colorectal cancers (CRC) is a rare occurrence in clinical practice. Moreover, metastasis to the ventricular system is even rarer. Here, we are reporting a case of CRC patient who had 4th ventricle metastasis without parenchymal metastasis. A 52-year-old male patient had a diagnosis of CRC 2 years earlier and received chemotherapy. He reported to an emergency department with abrupt vertigo, nausea and vomiting, and imbalanced walking. The lobulated mass was found in the 4th ventricle in magnetic resonance imaging. He was operated upon after aneurysm was excluded by MR angiography, and adenocarcinoma was found.
