False positive lymphography in Hodgkin's disease: a histologic-lymphadenographic correlation.

A series of 99 consecutive patients having a staging laparotomy for Hodgkin's disease was reviewed. Negative lymph nodes removed during the laparotomy were correlated with lymphograms reported as positive or suspicious. Four patients had large nodes with a prominent hilar area or irregular cortical fat deposits. In two other patients a cluster of small lymph nodes accounted for the radiologic misinterpretation.
