[In-flow of contrast into the liver--a rare complication during lymphography (author's transl)]

A lymphogram is described in which Lipiodol was found to have reached the liver from pelvic lymphatics. The common iliac and para-aortic lymph nodes had been invaded by tumour from a squamous carcinoma and this had produced complete lymphatic obstruction of the normal lymph paths. In addition, there was occlusion of the bifurcation of the iliac veins due to tumour, a finding also described by other authors. The causes for the finding of Lipiodol in the liver are discussed. The pathway by which the Lipiodol had reached the liver from the pelvic lymphatics, and the reaction of the liver parenchyma to the contrast medium, are considered.
