We report the case of a patient with a single liver metastasis of a mucinous colonic carcinoma that mimics a haemangioma in T2-weighted sequences. Although a very high T2 signal in non-cystic lesions is highly specific for the diagnostic of haemangioma, the use of gadolinium-enhancement MRI is recommended. In patients with a history of neoplasia, the diagnosis of benign liver nodules should be made with caution.
