Calcifying muscular metastases of colonic origin. Apropos of a case localized in the psoas muscle

: A case is reported of calcifying metastases of colon origin localized to psoas muscle. Emphasis is placed on the effectiveness of CT scan and MR imaging and the rarity of this localization. The presence of intra-lesional calcifications as described in hepatic metastases raises the question of the etiopathogenic mechanism and the predictive value of the detection of a calcified mass during the course of colon adenocarcinoma.
