A total of 24 patients with liver metastases of the calcifying type were detected during CT scan imaging for cancer of different primary origin (colorectal, ovarian, mammary, gastric, prostatic, melanoma). These calcifying metastases represented 27% of the 89 liver metastases cases detected, and the incidence of a colorectal origin for these calcifying lesions (20% of cases) appears to be highly significant, their number being relatively larger than reported in previous studies. Identification of liver calcifications of possible diagnostic importance requires a two-stage CT scan investigation, before and after bolus. Paraclinical examinations should be directed selectively towards the digestive tract when the primary tumor is unknown.
