Figure 1. A 19-year-old man with Klippel–Trénaunay syndrome (KTS). (a) Frontal 3D spoiled gradient-echo magnetic resonance lymphangiography maximum intensity projection (MIP) image, obtained 45 min after gadodiamide injection, clearly delineates several enlarged lymphatic vessels in the left lower leg with typical nodular appearance (arrows). Note the concomitantly enhanced superficial vein, which shows a lower signal intensity (arrowheads). (b,c) Angled 3D spoiled gradient-echo magnetic resonance lymphangiography MIP images, obtained 45 min after gadodiamide injection, clearly delineate several enlarged lymphatic vessels in the left lower leg with typical nodular appearance (arrows). Note the concomitantly enhanced superficial vein, which shows a lower signal intensity (arrowheads).
