Cerebellar brain metastasis from colon cancer

Biopsy-proven colon metastasis in the cerebellar vermis. Transverse axial T2-weighted (A) and FLAIR (B) MRI demonstrates a hypointense mass in cerebellar vermis. There is relatively little associated vasogenic edema. Postcontrast T1-weighted MRI in transverse axial (C) and sagittal (D) planes shows both internal and thin, peripheral enhancement.
