Lymphedema of the lower limbs is a well-known chronic condition. The cause of lymphedema can be either primary or secondary. Lymphoscintigraphy is a simple and reliable method for evaluation of lymphatic function. We illustrate the different lymph drainage patterns in 4 cases of lower limb edema, with either primary or secondary causes. In all cases, planar images were obtained after bipedal administration of 99mTc antimony sulfur colloid.
