Lymphographic and echographic findings in angioimmunoblastic lymphadenopathy.

Four patients with angioimmunoblastic lymphadenopathy with dysproteinemia (AILD) had lymphograms that did not show a consistent radiographic pattern. Instead, a spectrum of radiologic changes ranging from a moderate increase in lymph node size with slight "foaminess" to total nonopacification was observed. One patient with this disorder had gray-scale echograms that showed enlarged anechoic lymph nodes. The findings in this small group of patients with AILD are indistinguishable from the radiologic and echographic changes seen in malignant lymphoma.
