Contralateral displacement of abdominal viscera by a retroperitoneal liposarcoma: ultrasonic demonstration.
Occasional reports have described contralateral displacement of the kidney, gall bladder, or liver by masses, but no ultrasonographic description of this phenomenon has been published. To our knowledge, this is the first report of contralateral displacement of all three structures by an encapsulated, well-differentiated low-grade liposarcoma. The significance to the ultrasonographer lies in the fact that he may be the first physician, as we were in this case, to have the opportunity to recognize the true anatomical relationships of all three organs and to suggest that this tumor is more likely to be benign or slowly growing rather than a highly infiltrative process.
