Metastatic brain tumors from colorectal cancers are relatively rate. In previous reports, the incidence, ranged from 1.9 to 3.5 percent of all metastatic brain tumors. We reported 2 cases of metastatic brain tumors from colorectal cancers. Metastasis to the lung and liver were not found in 2 cases at the time of the diagnosis of the single brain metastasis. The CEA levels in the serum were highly elevated in these 2 cases. On a contrast-enhanced CT scan, tumors were equally demonstrated as high density and cystic, with a ring-like mass with surrounding brain edema. Brain metastases of colorectal cancer were discussed with a review of the literature.
