In medicine, lymphedema is "edema due to obstruction of lymph vessels or disorders of the lymph nodes."[1]
Diagnosis
Lymphedema should be distinguished from edema, myxedema, and lipedema.[2] Lipedema is more likely to spare the dorsum of the foot.
Physical examination
On physical examination, fast recovery of pitting is associated with lower serum albumin levels.[3] Fast recovery within 2-3 seconds, is more sensitive than specific at detecting hypoalbuminemia. Presumably this is related to the viscosity of the interstitial fluid thus hypoalbuminemic interstitial fluid can reform more quickly.[3]
Imaging
Oil contrast lymphography may be used for diagnosis. Whole-body lymphangioscintigraphy may help in the diagnosis.[4] Magnetic resonance imaging may help in the diagnosis.[5]
