Figure 7. Secondary lymphoedema– lymphangectasia. (a) Frontal image showing dilated right thigh lymphatics in a patient with right leg oedema due to right sided pelvic lymphatic obstruction by a large ovarian tumour (not shown). (b) Frontal images showing bilateral calf megalymphatics and (c) partial right thigh lymphangectasia in a patient with bilateral lymphoedema. Note also the dermal backflow around the left knee and collateral vessels in the mid left thigh (arrows). The aetiology was felt to be due to chronic bilateral lower limb cellulitis.
