[Malignant-appearing retroperitoneal lymphography findings in Whipple's disease--a source of possible misdiagnosis].

Whipple's disease may mimic clinically primary intestinal lymphoma. In addition, lymphographic findings in the paraaortic lymph nodes in Whipple's disease simulate malignant lymphoma. These severe tumor-like lymphographic changes are described in three cases of Whipple's disease. The data highlight the risk of misinterpreting of Whipple's disease as malignant lymphoma on the basis of clinical data and lymphographic findings.
