Her lymphoscintigram image at 45 minutes shows reduced flow of radiolabeled tracer to her left axillary nodes (Table 2, patient #5). C and D, 61-year-old woman with a secondary right lower extremity lymphedema (BMI 16; Table 2, patient #8). Her lymphoscintigram image at 45 minutes illustrates absence of right inguinal node uptake of radiolabeled tracer and dermal backflow.
