RT Journal Article SR Electronic T1 Renal pseudoenlargement secondary to retroperitoneal liposarcoma JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 640 OP 642 VO 59 IS 6 A1 Whitman, Gary J. A1 Wegryn, Scott A. A1 Lammert, Gary K. YR 1992 UL http://www.ccjm.org/content/59/6/640.abstract AB A case of renal pseudoenlargement caused by a large retroperitoneal mass is reported. An intravenous urogram showed apparent enlargement of the right kidney and a normal left kidney. Computed tomography showed a normal-sized right kidney. The discrepancy was due to magnification produced by marked anterior displacement of the right kidney by a retroperitoneal liposarcoma.
