Figure 2. 21-year-old woman with bilateral primary lymphoedema. Angled three-dimensional (3D) spoiled gradient echo magnetic resonance lymphography (MRL) maximum intensity projection (MIP) image, obtained 45 min after Gadoteridol injection, clearly depicts a reticular network of enlarged lymphatic vessels in both lower legs (small arrows). Furthermore, areas of dermal backflow are revealed bilaterally, indicating delayed lymphatic flow with neovascularization due to obstruction (asterisks). Note the concomitantly enhanced veins in both lower legs (arrowheads).
