Lymphangiogram is a test very similar to a CT scan, except the contrast dye is injected into the lymphatic vessels.

In this post we’ve included links to information about how the test is performed. It is not a commonly performed test, but some in the LGDA community have had it done. Of course, these articles about the test make no mention of lymphangiomatosis or Gorham’s disease, but they do provide a good overview of what is involved in having the test done.
