The CT appearance of normal retroperitoneal lymph nodes has been described. In many
instances the structures are too small to be identified. Other retroperitoneal structures,
such as collapsed bowel loops, vessels, and other perirenal structures, may simulate
the presence of nodes. CT is of great benefit in disease with bulky tumors, such as
non-Hodgkin's lymphoma, testicular tumors, etc. Its usefulness is much more limited
in disease that may have extensive nodal involvement but no significant enlargement
of the nodes. The accuracy of CT scanning in Hodgkin's disease and in many instances
of genitourinary tumors is questioned, and we submit that further studies are needed
to establish the reliability of this mode of examination.
