Imaging Studies
- Although infrequently required to establish the diagnosis, certain tests may be useful to confirm the diagnosis in complex cases, to determine residual lymphatic function, to establish treatment preferences, and to evaluate therapy.
- Lymphangiography was the criterion standard for evaluating the lymphatic system for many years.
- This technique has been shown to cause an inflammatory reaction of the endothelium of the remaining lymphatic channels, leading to scarring, atrophy, and even luminal obliteration.
- Lymphangiography has been replaced by less invasive techniques and should no longer be performed on patients with lymphedema.
- Lymphoscintigraphy has replaced lymphangiography.
- It does not promote further damage to the delicate lymphatic channels.
- This test can be used to define anatomy and patency, evaluate dynamics of flow and reversal of flow, and determine the severity of obstruction.
- Computed tomography (CT) scans and magnetic resonance imaging (MRI) have been advocated by some authors.
- These tests can delineate nodal architecture at a greatly increased cost, but they have very few advantages over lymphoscintigraphy.
- An indication for CT scan or MRI is suspicion of malignancy, for which these tests offer the most information.
- Doppler ultrasonography is also used by some to evaluate flow in the lymphatic and venous systems.
- The presence of a deep vein thrombosis is in the differential diagnosis of unilateral extremity swelling, and it may also occur concomitantly with lymphedema.
- This is a very cost-effective test in the appropriate clinical situation.
