Technetium-99m-albumin colloid lymphoscintigraphy in postoperative lymphocele.

An important use of lymphoscintigraphy is to evaluate extremity edema. Lymphoscintigraphy has many advantages over contrast lymphangiography in these patients. We report an unusual case of lymphocele of the left upper chest wall which was discovered incidentally during lymphoscintigraphic evaluation of left upper arm edema. This lymphocele was due to prior surgery, but in some patients the etiology is previous trauma or idiopathology.
