Obesity-induced lower extremity lymphedema. A body mass index threshold appears to exist between 53 and 59 when lymphatic dysfunction occurs. (Above, left) A woman with a body mass index of 53.3. (Above, right) A woman with a body mass index of 78.3. (Below, left) Lymphoscintigram from the patient shown above, left with a body mass index of 53.3. Note normal transit of technetium to inguinal nodes 20 minutes after injection. Arrows indicate inguinal nodes, black arrowheads show tortuous lymphatic channels and dermal backflow, and white arrowheads mark the feet where the radiolabeled tracer was injected. (Below, right). Lymphoscintigram from the superobese patient shown above, right (body mass index of 78.3). Note the delayed transit of tracer to inguinal nodes 3 hours after injection, tortuous collateral lymphatic channels, and dermal backflow consistent with lymphedema.
