[Obstruction of the sigmoid colon due to an ovarian metastasis of colonic origin]. / Obstruction du côlon sigmoïde par une métastase ovarienne d'origine colique.

ABSTRACT

The authors present a case of left ovarian metastasis from colon carcinoma causing sigmoid obstruction. On US and CT the ovarian mass appears as a primary malignant lesion. The lesion caused a regular sigmoid stenosis which mimicked, on barium enema, a volvulus and screened the primary lesion.
